Watlow EZ-Zone (R) LabVIEW Driver

I'm using the Watlow EZ-Zone LabVIEW Driver Example.vi to read the temperature of my Watlow controller with the "Parameter" set to 4001. Does anyone know how to find the Parameter to "SET" the temperature from the massive list "EZ-ZONE ALL Modbus register list in Excel" located on Watlow's website http://www.watlow.com/literature/manuals.cfm?prodmktcat=3&famid=15 ?

Hi mcnearymw,
I will be glad to help you with any LabVIEW issues you're having, but this issue seems to be related to Watlow's documentation. It is possible that someone else on the forums is familiar with using Watlow devices in LabVIEW and can give you some advice. You may want to contact Watlow about this issue.
Good luck with everything!

Looking for LabView driver for Watlow 96 Series Temp. Controller.

In need of LabView driver to control a Watlow 96 Series Temperature Controller. The controller has a RS232 output, so I'm preferably looking for a serial port driver. Thanks in advance.

Nevermind....I found some very useful information in Brian Vibert's postings. Do a search for Watlow 96 Series.

Watlow EZ-Zone PM ENET RS-485

I am having trouble talking to Watlow EZ-Zone PM controllers with labview.
I cannot get the ENET to RS-485 to show up in Max. I discovered that this is due to 64 bit windows? However I can talk to the ENET to RS-485 using VISA Resource Name: ASRL::xxx.xxx.xxx.xx::1::INSTR where xxx.xxx.xxx.xx is the IP of the ENET to RS-485.
I also tried using the Watlow driver however if I put the above resource name in for the PC Comms Port in the example included with the driver and try to initialize the port, I get the following error:
Error 1 occurred at an unidentified location
Possible reason(s):
LabVIEW: An input parameter is invalid. For example if the input is a path, the path might contain a character not allowed by the OS such as ? or @.
=========================
NI-488: Command requires GPIB Controller to be Controller-In-Charge.
I assume this is beacuse the ASRL::xxx.xxx.xxx.xx::1::INSTR is not a valid input to the Watlow driver.
Please let me know if you have any solutions. Thanks!
System:
Windows 7 64bit
labview 2011 32bit
Max 5.5.0f0
ENET to RS-485
Solved!
Go to Solution.

So I borrowed a USB to RS-485 from another project and got it working with the Watlow controllers. I also used Free Serial Analyzer to "sniff" the serial commands sent/received over the serial port. Here is what I found out:
Seems like the .DLL sets up the serial port with the following parameters:
Baud Rate=38400
WordLength=8
StopBits=1 stop bit
Parity=No parity
EofChar=0x0
ErrorChar=0x0
BreakChar=0x0
EventChar=0x0
XonChar=0x11
XoffChar=0x13
ControlHandShake=1
FlowReplace=64
XonLimit=2048
XoffLimit=512
ReadIntervalTimeout=4294967295
ReadTotalTimeoutMultiplier=0
ReadTotalTimeoutConstant=0
WriteTotalTimeoutMultiplier=0
WriteTotalTimeoutConstant=0
Then the .dll continuously sends a purge command:
Purge mask=TXCLEAR: Write requests
Followed by a write command:
55 FF 01 03 00 00 00 E4
This must be some kind of connection check?
When I try to read a value from the controller, in this case the controller at address 1, parameter 4001, instance 2, the DLL writes this:
55 FF 05 10 00 00 06 E8 01 03 01 04 01 01 E3 99
It then reads:
55 FF 06 00 10 00 0B 88 02 03 01 04 01 01 08 C2 09 D3 75 AA 85
Which is a float on the order of -100 (the value is bouncing around).
I tired sending the read value hex to the controller with VISA however, I never got a response.
Any ideas on how to re-engineer this driver/get it to work with VISA?

An instrument driver is a collection of functions that implement the commands necessary to perform the instrument�s operations. In short, someone read the instrument user manual and implemented some of the functionality in a program for the end user. Instrument drivers are not necessary to use your instrument. They are merely time savers to help you develop your project so you do not need to study the manual before writing a program.
There are example VI's in LV on Instrument Connectivity. If you go to the Help menu >> Examples.. >> I/O, you will see a couple and Examples.. >> Fundamentals for File and String manipulation. I would suggest tweaking them to suit your application. Also the specific command that your instrument responds to can be found from it's manual.

Looking for labview driver to control Tennesy Chamber

Looking for Labview driver to control Tennesy Jr Environmental Chamber
(Watlow series 942 controller) LV6.0
Email [email protected] if you can help out.
Thanks,
David.

The first place to look for stuff like this is the vendor's web page--in this case www.watlow.com. How did I know this? I guessed. You can typically guess 90% of company websites...
In a couple minutes I was able to find your controller and a document on how to communicate with it. If you email me I can send it to you (it's too big to post...).
Next, reading the document (which by the way contains a good basic primer on serial communications)I saw that one of the protocols you can use for communicating with the 942 is Modbus RTU. I can also send you a set of modbus drivers.
Hope this helps in thermal testing your chips...

Where can i find a Labview driver for the "8990a PEAK POWER ANALYZER" it's not on NI's site.

where can i find a Labview driver for the "8990a PEAK POWER ANALYZER" it's not on NI's site.
if there is no driver maybe you can tell me the closest instrument that comes to this one from the list at,
http://search.ni.com/query.html?lk=1&col=alldocs&nh=500&rf=3&ql=&pw=595&qp=%2BContentType%3AInstrumentDriver+%2BIDNetManufacturer%3A%22Hewlett-Packard%22&qt=peak+power+analyzer&layout=IDNet
so i could modify and use the driver

Hello,
It looks like Agilent/HP makes the 8990A, but I was not able to find a driver for it that we or Agilent has written for this device.
Since I am not familiar with the 8990A, I cannot recommend which drivers might be similar, but you are pointed in the right direction. Agilent themselves might know more about which models use similar command sets so that you can modify a driver easily.
Hope this helps.

Is there any LabVIEW driver for the Agilent 53147A counter/power meter?

I am trying to find a LabVIEW driver for the Agilent 53147A counter/power meter, but I cannot find it. Is there any?

NI does not have a driver and a quick check with Agilent shows that they don't have a driver either.
You can go to http://www.ni.com/devzone/idnet/ and request a driver. You will also find links on how to create your own driver. Your other option is to use the Instrument I/O Assistant.
p.s. In the future, you should use the Instrument control board for posting questions. this board is for NI counter/timer products.

RS232 Labview driver for SR830 lockin Amplifier

Hi,
I want to install Labview driver for Stanford Research SR830 lockin amplifier for RS232 port. NI has drivers for GPIB but I could not find any for RS 232 comm port.
Please let me know how can I find driver for RS232 port.
Regards,
Nitin

Dear Jason S,
I also want to communicate with sr 830 with the RS232 interface. You said I had to rewrite the whole thing. What does that really mean? Rewrite the driver? If so, what language will it be?
JasonS' wrote:
Hello Nitshu-
As you mentioned, this driver only supports GPIB, and not RS-232. This driver was originally created in 1994, so it was not created using VISA. This means that to convert this driver you would need to essentially rewrite the entire thing. There are not currently any plans to update this driver to support RS-232, but you could easily communicate with it by adding a GPIB Interface to your system.
Let us know if you have any specific questions we can help answer.

Thank you for answering my question

Can Labview 7.0 control an instrument without the labview driver?

hellow,i have an instrument which do not have the labview driver,its output signal is RS232,so can i use labview7.0 to read the signal? thanks!

You sure can. There is a popular program to check on serial hardware, the loopback.vi. It sends out a signal and reads in a signal. You can modify the vi to send a signal to whatever you need to or receive a signal from whatever you want to. So if you just have an output signal to read in you can modify it to just read in that output signal into a graph or anything you'd like. So you could just get rid of "serial port write.vi" or that entire sequence if you wanted to. I hope that helps.
