Omron (CQM1-CPU45-EV1) PLC communication and control

hi,
we have an Omron(CQM1-CPU45-EV1) PLC with RS 232C communication connected to instuments for control and monitoring of an aplication.
Unfortunately our old pc broke down and now we have to set up thisPLC with a new labview interface.
I'm not an experieinced Labview user i would need you help (tutorial) how to communicate the Omron PLC with the labview and how to acquire data and control the application.The task is somehow urgent so i would appreciate advice at your earliest convenience.

PLC Communications with Labview

How do I view and record data from my plc to labview, currently we are using autmation directs DL205 with the 260 processor

If the DL 205 communicates through the Modbus protocol, you could use the Modbus library. This library consists of a bunch of VIs which can be used for Modbus communication. Think of them as advanced Serial read/write VIs. However, if you are looking into monitoring, datalogging and controlling the registers, then I would recommend the LabVIEW Datalogging and Supervisory Control Module. Using shared variables, you can then easily bind, control and talk to the registers and most of the work is taken away from you.
If the DL 205 doesn't communicate throught the Modbus protocol, then you would need an OPC server (like the NI Industrial Automation OPC Servers) and the LabVIEW DSC Module. You can then communicate from the LabVIEW DSC Module with the OPC server.

How to implement Modbus Ethernet communication in Lookout, if we want to simulate the PC as PLC ?

Problem Description :
Dear Sir,
We are doing a project where we are using Lookout with
Front end Modicon PLC. The communication is by
Ethernet, using Modbus.
Since the installation is at a distant place, we wanted
to use another PC (running Lookout) to simulate the
PLC. For this, we tried to communicate
a: the server Lookout PC running Modbus Ethernet mode of
Modbus object as Master
b: with another PC (for simulating the PLC) running
Modbus Slave
We did not get any communication. (we have given the
details of what we have done, at the end of this email)
We also tried connecting the above 2 PC's as
a: the server Lookout PC running Modbus Serial mode of
Modbus object as Master
b: with another PC (for simulating the PLC) running
Modbus Slave object
Again we did not get any communication.
If instead of PC (b) we connect the Modbus simulator to
PC (a), there is no problem in communicating
Please let us know how to go about establishing the
communication between 2 PC's using Modbus serial,
and Modbus Ethernet. A detailed step by step procedure
would help us a lot.
Thanking you
Warm Regards
Raja Mahbubani
Procedure of our trial with ethernet.
This is what we have done in detail.
On PC A:
We created an object (Pot) and connected it to
the modbus data member of the modbus object say 40001. In the
properties of the modbus object we selected modbus ethernet mode
of communication and in the IP address field we wrote the IP
address of the machine B to which we are trying to communicate
i.e. 152.63.50.2.
On PC B: we tried the following two methods
Trial 1 : We created a modbus slave object and
inserted an expression for the same data memeber to which the
object was connected hoping to get the value of the pot of machine
A on machine B.
Trial 2 : We created a modbus object on machine B and we wrote
the IP address of machine A and inserted an expression for the
same datamemeber to which the object was connected hoping to get
the value of the pot of machine A on machine B.

The ModbusSlave which comes with Lookout currently supports only Serial communication. So, you cannot use Ethernet between your two PCs. At least not with Modbus Master-Slave setup (if you must speak Ethernet between the two PCs, IPASCII object lets you do that, but then you'll need to implement your own protocol).
Since all you want to do is simulate a Modbus PLC on a PC, you can use the Serial mode of communication for now. And later on just modify the Object in your Server Lookout to use the Ethernet mode.
For setting up a Serial Modbus Slave, use a null-modem cable between the two PCs (lines 2 and 3 are swapped). On your PC 'B,' create the Modbus Slave object with the right COM port for that PC. And on your PC 'A' create the regular Modbus Object as if you w
ere connecting to the Modbus Simulator box. The only difference here is the cable. The simulator box uses a straight-through cable whereas the Slave needs a null-modem cable.
Hope this helps.

Everything works well, from the LPD OPC Server to creating TAGS..to using the HMI wizard on the front panel,...but there is no communication with my hardware. An NI Application Engineer came by yesterday and we concluded that this was a hardware ware communication problem. I talked with an Automation Engineer in Austin yesterday and he told me to try RSLinx and see if I could get it to communicate with the hardware. I like that HMI wizard, it is pretty cool! I am pasting a copy of an email I sent to Allen Bradley so you can see a little bit more information about my hardware. thanks for your help again Khalid.
{{{I am having much difficulty in communicating to my PLC 2 communication port or through my RS-232 port on my 1771-KG card. I am using a serial (null modem) cable on com port 1 on my PC.

Can you please give me the pinouts that I need to communicate with the processor port on the PLC and or the 1771-KG card? Please contact me as soon as possible for I really need to get this to communicate so I can get started on this HMI upgrade. We are using PanelMates as HMI?s, but they are 13 years old and are failing frequently as well as being obsolete.

Omron cp1h plc communicate with labview

I have some trouble with the communication of omron CP1H PLC and labview 8.20 which is the versionc can be free used only for one month.
During this test,I download visaruntime4.2 version. I don't know wheather this visaruntime version is suitable for labview 8.20.
In my test ,I fit the baud rate :9600,date bites :7,parity:even,stop bites:2.0
when I write @00RR0000000141*\r to the examle of (basic write and read).vi,then can read a string.but when I write @00RR00000001 and let this string pass throug a fcs.vi made @00RR00000001 become @00RR0000000141*\r,then I can't read anything.I am puzzled.
And when I imitate the program of the example ,I find that this program can't opration.
what is wrong with my test?
Thank you for your regards!!!!!!!!

You should keep your questions to the same topic in the same thread. You show up on the forum as an NI employee based on the blue bars so I would expect you would know the ettiquette of the forums a bit better than the average new user.

Siemens S7 300 PLC and Labview Communication

Hi,
I am attempting to communicate between Labview 7 and a Siemens S7 300 (CPU 314) PLC. I would prefer the communication to be over Ethernet or RS 232. Could you help me out with this implementation and let me know what additional hardware/software I may require for doing this.
Thanks,

I still havent figured out where the OPC server comes in and whether it is an option or a necessity.
Using OPC is an option.
Siemens has an the add-on ($$) library/FB that includes code for enabling Modbus communication with S7 300 CPUs. I've never used it, but info is here.

With its MODBUS function block (FB) and the CP343-1 and CP443-1 SIMATIC S7 communications processors, Siemens can supply a proven solution for the integration of SIMATIC automation systems into other system landscapes. This function block enables data to be exchanged easily between MODBUS-compatible devices from different manufacturers and SIMATIC S7 stations from S7-300 and S7-400 systems.

First of all, Thank You very much for Your answer.
I'm using the TS Adapter that make the conversion from MPI to the serial bus.
I have made yet control panels to supervisor systems with Omron PLCs and I correctly use the DataSocket with the DSC module: with Omron PLCs I've never had any problems of communications. The problems is now with Siemens. For the communication between control panel and PLC I have to use the internal modem of my computer and the OPC is S7_MPI of IA opc Server.I wondering if this OPC is ok for modem communications (inside there is a form to insert the phone number of the remote station) or if every kind of modem are compatible with S7-300 modem it has inside.I've noted that my computer modem don't do the phone number when i run the front panel!In running mode, if I take a look to the Block Diagram and I click the "Highlight Execution" button I don't see any animation on the code generated by the HMI Wizard to connect the only one tag to the DataSocket URL.
Have You any other suggestions to solve the problem?

What communications protocols does LabView support?

A customer of mine is using LabView. He has asked me if I can communicate to it using a PLC. Either GE Fanuc or Allen-Bradley. I need to know what methods of communication that LabView has available to talk to these PLC's.

The short answer is: whatever protocol you want to talk...
I have developed applications talking to AB stuff, modbus (which will cover most PLCs) and even TI's old proprietry PLC protocol. There are lots of tools for making the connection in lots of ways.
What are they specifically needing--or do they know yet?

It's better or necessary open and close communication with instrument every loop?

I must communicate with my instrument, but I must change its value, for example temperature, every loop. See the Figure to understand:
I think that it is better if I open communication with my instrument out of while loop so I many operation: if I put Open VISA in While loop I open VISA session every loop, instead I think it is not intelligent. Can I open VISA SESSION out of the while loop or it is an error for EXCELLENT LABVIEW VI and I must open and close VISA SESSION every times I must talk (and set) with instrument? What is the better way?
Message Edited by Michelle1892773 on 02-22-2010 02:00 PM

Something like this?
I do have to say, i don't know what is happening in the false case of yours, but if nothing happens with the 100 that is wired to the shift register, once you enter the true case, the value in the shift register will always be great than "i". You might as well do what I have done then. However, if something does happen with that number in your false case, then keep it the way you have it.
That being said, why is the condition there to see if it has looped 100 times before doing the visa write??

6500a e710 a-f - Scanner Communication Error Windows 8.1

We have been experiencing issues with scanning whilst connected via USB, using the HP Scan software. The software returns an error message saying scanner communication cannot be established, half way through scanning. Then HPScan.exe fails to load again. The printer just says “scanning cancelled” on its display.
This is only effecting one model of PC and that is a HP 8300 Ultra-Slim PC.
We are running Windows 8.1 64 bit from an image install. However, I have tested this with a fresh Windows 8.1 retail installation and get the same problem.
We have tried various actions to fix this:
- Various accounts, admin accounts, domain admin accounts, local accounts etc.
- Uninstall and reinstall. Basic and Full driver packages including the latest versions
- Removed all other HP software from PC including registry keys
- Used built in Windows 8 scan software with basic driver
- All USB ports tested including 2.0, 3.0 and powered / non-powered
- Replaced cables
- Re-isntalled USB bus drivers for 8300
- Followed the print/scan doctor which shows a driver error - scandriver unable to communicate with product
- Run HPScan in compatibility mode for 7/XP
- Updated firmware on printer
- Installed latest Windows Updates
- Checked WIA service and dependencies are running
- Semi and Full factory resets on Printer
- Shell hardware detection service set to manual
- We have replaced the printer for an affected user - same issue
- Also replaced PC for an affected user - same issue.
- Updated PC BIOS
I have tested connecting the printer to the router with a network cable and then installing printer as a networked device rather than USB and then the hpscan.exe works. So this is only an issue with USB (though it wouldnt be practical to try and talk 200+ users through networking their printer).
As you can see, we have tried almost everything. Interestingly we havent been able to replicate this issue in one of our main offices - despite collecting the same PC and Printer from an estate and bringing it back to an office.
We have also sent out a working PC and Printer combo to an affected estate office and it has not worked there.
Our Estate Offices connected via an ADSL Router and "My Documents" are re-directed to a network location. Could a failure in accessing this network location cause the problems? I have tested connectivity to network store from PC and it accesses the files fine.
Any solutions would be greatly received, I have spoken to HP After Sales support but not received an working solution yet.

Greetings, @Scammell29
I have read through your post and have very ideas left for you, as you've tried quite the load of troubleshooting!
I am thinking the issue could be power related, so try a power reset and plug the printer in directly to the wall outlet. Avoid power bars, surge protectors, etc. Just a direct plug in to the wall to test the power. Afterwards, see if you still receive the communication error.
If the issue continues, next try a disk cleanup, the instructions are included in this guide: A 'No Computer Detected' or 'Connection Error' Message Displays during Scanning for HP Officejet 650...
If the error still persists, perform a Clean Boot and restart the PC and then disable the Firewall and Anti-Virus scanners.
Please let me know the results!
Good luck

Serial communication does not work in an executable.

I have created a vi that communicates with a serial device. It works fine on the computer that it was creatd on. I then created an application and then built an installer to put it on another machine. The second machine does not have LV 2009 on it. Once installed on the machine the vi does not work. When it runs on the computer with LV 2009 the the com port control is a pull down, and it lists all comports on the computer and then you select the one you want to connect with. The computer that the vi is installed on does not list the available com ports. This leads me to believe that there is no serial comms support in the installable version. What do I do now?? I noticed that you can add "Additional Installers" when you build the installer and one of them is NI-Serial 3.4. I try to add this and a message said that it had to get, so I didn't use it thinking it was more than I needed and that standard com port driver would be included. Am I wrong here or am I missing something else?? All help is greatly appreciated.

Hi at all!!
I'm new in NI forum.
I have one similar problem. My VI communicate with external device on serial port. The VI work very well, but when I create executable (.exe) file with Labview application builder (on Labview 2010) the .exe don't use serial port!!! The executable run perfectly (nothing error or warning by the application builder), but the serial data on selected COM port isn't send!!! Also on the PC where I developed the VI!!!
What do you mean by your last sentence? Are you trying to say that you can't run your executable even on the same computer on which you developed the application? If so, was LabVIEW open when you tried to run it? Try quitting LabVIEW; if you had previously run your VI and didn't close the serial port, LabVIEW might have kept it open, which would prevent the executable from accessing it. If the executable won't run on the development machine it's unlikely to be resolved by installing VISA since you need that installed for the VI to work properly in the development environment. Do you have any error handling in your code that would indicate if an error occurred after trying to write to the serial port (an indicator on the front panel, or a call to Simple Error Handler)?

Problem with serial communication PLEASE HELP

Hello everybody !
I'd like to ask You for some feedback on my wierdo problem that I got with my program.
I have built a device that detects changes in magnetic field. It is used for detecting vehicles passing it on a highway. Generally the main components communicate with each other by RS-485 protocol, but I would like to connect the device to a PC. To do so I am using a RS-232 protocol (I have a RS485=RS232 hardware converter).
Now, I made the program (even two), which generally works, BUT some wierd things are going on sometimes; it happens that I have a problem to get a communication (after that, resetting the device by un-powering it helps, sometimes I have to restart the PC as well) but overall it happens quite not so often. The project itself is for passing one of my subject on the university - so I have to run the whole thing over there, here comes another problem : the program did not work on all of the bunch of PC's that are there. Same thing happens on my notebook. The effect of 'non working' is : I am recieving same data packet that is beeing sent... BTW : notebook does not have a RS232 port and I am using a USB-RS232 calbe converter (to count it out from the reason of problems I have checked it on my main PC and it works almost fine - almost because ocasionally I am getting the same sympthomps as I mentioned before ).
Other problem is, when it works, that I am loosing communication for couple of hundreds of miliseconds and then it comes back to normal (i can see it on the osciloscope).
I alredy looked for some answears here and there, and I found some suggestions about using 'buffer cleaning method', unfortunatelly I kinda do not know how to do it, and might that help anyways ?
I also thought about using VISA drivers, but I am having trouble with it as well - the damn thing just does not work.
My very bling guess is that everyting that I am expierencing is about using the communication protocol and seting it right. I am attaching both of the programs, PLEASE anyone pretty pretty help I totally ran out of ideas and knowledge and day after day I am turning it on and off on my PC and notebook hoping some miracle will occour ...
Many many thanks in advance !
Best regards
Tom
P.S. the program is very unfinished (man things are just put in), the main thing I am struggling now is getting, and setting the communication protocol right.

The biggest problem I see is in the sequence:
Write out a string.
Wait 50 mSec.
Ask how many bytes have been received.
Read that many bytes.
Can you guarantee that the data can make a round trip in 50 mSec?
You should know that the SERIAL PORT WRITE completes NOT when the data has been sent out the port, but when it has been BUFFERED for sending. In other words it returns and starts the timer BEFORE it is actually sent.
Also, given that there are 232 -> 485 --> USB conversions involved in both directions, I would bet that you are sometimes not allowing enough time for the data to get back.
If you can control the protocol of what gets sent back, I would change your receiving logic. I think you should check for a carriage return or some other delimiter, and not react until you get that character (or until a reasonable timeout expires).
In other words, try synchronizing the two ends. Something like:
N = Get # bytes at port
Read N bytes from port (flush any characters waiting).
Write out command string.
TimeLimit = NOW + 1000 mSec (or whatever)
S = ''; (Working string)
repeat
N = #Bytes at Port
If N > 0
S = S + Read N Bytes
Found = Search String for Delimiter
until Found or (Now > TimeLimit)
If Found, parse string S
You are also re-initializing the port (SERIAL PORT INIT) every time thru the outer loop - that's unnecessary.

MAX communication hangs after Standby Mode(with GPIB PCMCIA)

I have a IBM Laptop with MAX 2.2 and a GPIB PCMCIA Card installed. After booting the computer I can communicate with GPIB instruments without problems. After I get the Laptop out of a Standby Mode, MAX can not make any connection to GPIB devices; when I scan for Instruments it hangs as well.
The troubleshooting wizard tells me: one or more GPIB interfaces failed.
Does anyone have the same problems or solutions ?

On the NI-488.2 2.0 download page it is mentioned that that driver does not support standby mode. No such mention is made on the download page for NI-488.2 version 1.7 (which I need to use for my PCMCIA-GPIB interface), although the 1.7 release shows very much the same problem: After stand-by, communication with the GPIB port is no longer possible.
The Visual Basic example tool for preventing stand-by may help those users who are familiar with VB, but it does not help me.
Frankly - what I'd like to see is an improved NI-488.2 version that does support stand-by. Does NI consider providing such an upgrade/patch?
