National Instruments makes several PID controllers. I have one that is no
longer offered (P/N 320563-01), but I haven't gotten it tuned up yet.

Running two Eurotherm 3216 temperature controllers using the driver available from Labview

Hi All,
I am trying to control two Eurotherm 3216 temperature controllers using the driver provided by NI at http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=7F14CDCB24923797E04400144F1EF8.... Specifically, I am using the "Temperature Control Monitoring" example.
I have been able to operate a single temperature controller using this code. However, I need to operate two controllers, and I havent been able to modify the code appropriately to do it.
I initially tried just repoducing the entire code and running it but that provides me with an error. However, if I run the code while using "highlight execution" it works just as I need it to...except to slowly for my purpose.
If anyone has any insight as to how I may run both controllers, I would really appreciate it.
Thanks

Here something’s to try.
1)      Make sure both controllers have RS485 comms modules installed
2)      Connect both controllers in Daisy Chain configuration using the EIA485 instructions from Page 16 of the Manual you mentioned.
3)      Ensure both the KD458 and the 3216 controllers have identical Comms configurations. ie Baud Rate, Parity etc
4)      Verify your setup: In the "Temperature Control Monitoring" example” change the Unit Address, Baud Rate, Parity and Break Length to match the 1st controllers values. Verify that you can communicate with the 1st controller.
5)      Using the Same "Temperature Control Monitoring" example”, NOT a second copy, change the Unit Address, Baud Rate, Parity and Break Length to match the 2nd controllers values. Verify that you can communicate with the 2nd controller.
Comms problems are difficult to fault find so be methodical and you will succeed.

Chromalox 6040 and 6050 temperature controller with RS485

Hi,
I have a Chromalox heater and the Tempererature controllers (6040 and 6050). Both controllers has the RS485 hook-up. I would like to know how to communicate with these devices. The devices themselves can function as an stand alone units with PID controller installed. These devices can be used with automatic or manual control. I would like to set it on automatic and control it from Labview. I am currenlty using the Fieldpoints modules with Labview 2009. I have several questions: 1. can I wire the RS485 2-wire connector directly to the field point module? 2. if I need an RS 485 converter, I will use the RS485 to USB. Would I then just use the RS232 visa? 3. there are two connection on the controller for the RS485, I am not sure how to wire that together as twisted wire. I have looked at the forum on the subjects and find bits and pieces of info.. I would like more directions.
Thank you,

Sorry, I believe I convoluted the issue here at hand. Let me retract my earlier statement and say this. Your FieldPoint module has the RS232 port on it, where you can write serial commands out to the device (I mentioned using Optomux earlier, while this is possible, upon second thought it is unnecessary). You can then have the RS485 port write out to your temperature controllers. Is this what you are trying to accomplish? You should be able to wire the connections directly to the FieldPoint module. Sorry for convoluting the issue earlier. Does this answer your question more closely? You mentioned using an RS485 to USB converter, where does that come into play? I understood that you wanted to go from the FieldPoint RS485 port to an RS485 port onthe temperature controller?

Temperature measurement alongside other data measurement

Hi all,
I'm using Labview to automate a drop delivery process. I am installing temperature controllers and want to first bring the temperature up to a certain range, then start the drop process, and also display the temperature the entire time the drop process is running. My idea was to start the temperature controllers in Labview, wait until the output temp reaches within a certain range, then start the rest of the process but in the meantime keep displaying the temperature.
The best way I've found to do this so far is to make a stacked sequence. In the first frame, I start the temperature controllers, use a timed loop that "continues" until the temperature reaches a certain range, then cause it to go to the next frame. The next frame has another timed loop so the temperature can keep being read, and the drop delivery code. The problem with this is I have two output boxes for the temperature and I'd like just one.
So I guess I have two questions - I'm sure someone could think of a better way to do this, or if my way described seems feasible, if there's a way to have an output from two separate loops in two separate frames in a stacked structure display as the same output in the interface.
Hopefully I explained that okay! I appreciate any and all advice!
Laura

Laura,
Welcome to the forums and the Developer Zone! Your idea of using the stacked sequence will certainly get the task done as you have described it. The downside of the stacked sequence is that it is impossible to repeat a previous sequence state or otherwise alter the execution sequence programmatically and editting the structure to insert new states (in the middle not the ends per se) can be a bit painful. A more versatile option is the "state machine" architecture. It offers much of the sequence control features of the stacked sequence but gives you more versatility in ordering your states. Check out this community page to see some examples. https://decibel.ni.com/content/docs/DOC-8410
You might also check out the JKI String Based State Machine architecture. They have a drag and drop template for a real solid state machine setup and some tutorial videos on their site for using it.
Good luck

How to use shared variables to address multiple Watlow controllers on the same COM port

Hello,
I am trying to use LabVIEW 2010 to control 4 Watlow temperature controllers on one COM port. 3 are Model 96 and 1 is an EZ zone controller. Each controller has a unique modbus address, and I am trying to read from and write to individual registers (such as closed loop setpoint) using shared variables. I am getting return data when reading (although the data appears to be invalid), but am unable to change the value in the register by writing. How can I be sure that the Modbus server is sending commands to the correct controller?
Chuck
Solved!
Go to Solution.

Peter,
Thanks for the reply. I have actually solved that problem. I realized that the Modbus server address has to be the same as the controller's Modbus address.
I have, however, run into another problem. Perhaps you could help me with that. I have a system with 4 Watlow controllers, 3 are series 96 controllers, one is PID only and 2 are ramping. The 4th controller is an EZ zone. I am using RS485 for communications and the controllers are all wired in parallel for communications and power.
I have set up 2 Modbus servers for 2 of the controllers.
This is the first I have ever worked with Modbus based communications. I have successfully programmed using the Modbus read/write VIs, and am wanting to move to shared variables. My questions right now revolve around addressing, Modbus I/O servers and COM ports. Specifically, at this point, I know the addresses need to match up between the server and the slave device (Watlow controller in my case), how many servers can I create and use on one COM port? If the number is limited, is there a way I can specify an address that I want the server to talk to? Will the broadcast mode work to request data values from the controllers?
I'd appreciate any information you can help me with, or if you could point me to some sort of concise 'How-To' for Modbus communication.
Thanks.

Failure of LabVIEW DSC 8.0.1 to yield values of Modbus RTU holding registers

So, I know what I'm doing--or used to. Have done this before in LV 6 and 7. Previously used Lookout OPC drivers and the "Tag Engine".
Recently with 8.0.1, I first set up the Industrial Automation OPC servers (AKA Lookout) to communicate with the holding registers (40,001-49,999) of my modbus rtu Watlow 96 and MLS316 temperature controllers. Subsequently, with the Server Explorer all of my 133 parameters on our 2 rs485 serial ports are communicating bidirectionally.
So now Duh, why can I not bind a shared variable to register, say 40,334, and eliminate the OPC? The data is always reported as bad. Neither can I link shared variables to these addresses through the OPC I/O server.
Am I missing something? Are there any examples of code available where individual modbus holding registers are communicated with bidirectionally?

Well, this may seem rather silly but I viewed the video demo that NI has on binding modbus registers to shared variables before I even made my attempt.
Now, differing from the demo video, I am using modbus RTU on a serial port. Also differing from the video, when I create my shared variables, they are not placed in the same lvlib as the modbus server just created--LabVIEW prompts for a new library to be created.
Could the NI product service staff please test with a serial modbus RTU device (a real living creature and not just a simulation please) the bidirectional communications and prove functionality with the Shared Variable Monitor of your product? I suggest that you attempt communicating with holding registers 40,001 through 49,837.
By the way, my com is set up correctly for I can view and or change all of the desired modbus RTU registers using the OPC Lookout Protocol Drivers through the Server Explorer.
Please do not send me any more links to videos that test with simulations. A real solution is required.

Why can't I get a PID to tune without having an offset from setpoint?

I am using the basic PID algorithm supplied in the PID toolkit and after calculating the terms as described in the manual, my system controls quite well. However, there is about a 2-3 degree offset below setpoint on my heater.
I am just starting to use the toolkit and have it controlling a small heater on a piece of tubing, with a thermocouple on the inside wall.
I have turned up the proportional gain and gotten the offset to get smaller, as well as increasing the integral action. Ultimately the system has such high gains that it becomes unstable and begins oscillating wildly.
I have tried to leave the system alone for a long period of time and the integral term never seems t
o push the temperature the last little bit to the setpoint.
Is there anybody familiar with the toolkit and PID algorithms who could make suggestions about what I might try to get something a little better?
I am using Fieldpoint TC-120 modules to read the temperature and controlling the heater with a PWM-520 module. I have the duty cycle of the PWM module set to 1000 ms, and am running the PID loop at 500 ms. (maybe that is affecting my control)
Thank you for your help

Hi,
I have encountered the same phenomenon.
Increasing the derivative action seems to dynamize the system so it will
reach the setpoint.
It is still strange to me, since all temperature controllers I use don't
need any derivative action.

How do I control furnace temps (ramp and soak)? What hardware do I need?

Please help me~~~~
I use Labview version 8.2 and Compact Field Point. I currently have a small Lindberg/Blue furnace (120V, 6.8A, 8KW) that has a mounted Lindberg/Blue UP150 programmable controller. The temperature control is not currently connected to my PC (and that's a pain).
I would like to replace the present furnace controller with labview control through Compact Field Point. I need to create a ramp and soak program in labview. My
program must be able to:
Soak at 300C for 30 min
ramp to 650C
soak at 650C for 15 min
ramp to 700C
soak at 700C for 10 min
cool to 300C
repeat the above steps as many times as desired.
I am familar with labview but have never controlled any furnace temps. I have figured out that I will need the PID control toolkit. But I'm totally stumped about the hardware I will need. I have searched everywhere but can't find an explanation. I have Compact Field Point and the furnace. What hardware goes inbetween? Just what hardware does the PID toolkit (PID VI's) send a signal to? It seems to me the PID would read a thermocouple and then send a signal to some sort of current regulator that sends a varying current to the furnace. Am I way off? How do I set this up. Can anyone recommend a good book or web site that explains how to set up furnace control using labview?
I really appreciate your help. I'm at the end of my road without it. Thanks alot.

If you can, use a solid state relay as this will be the most reliable and noise free solution to switching. Switching 8kW loads with a relay can lead to arcing of the contacts after a while (and other issues), this is bad news for computers. For an 8kW device you will need to mount the device on some form of heatsink / dissapation surface. Solid state relays normally use an opto-isolated coupling which can usually be powered in the range 3 to 24v. This is connected to the control output of your selected controller.
For control of this sort I personally I prefer a dedicated controller, I use a PC for data logging, program management and monitoring. This is for reliability more than anything else, an NI controller won't come with integrated display and controls to set the device and the foot print in the panel is considerably larger. They also take an age to boot in comparison. You should also consider that you could get an electrical engineer to fit a standard controller with suitable solid state relay etc. and that will help you meet any health and safety requirements easily and quickly! Don't forget than any modifications will need to meet local regulatory requirements such as CE and thus circuit diagrams must normally be produced etc.
If I have the choice of selecting a controller, I like the Eurotherm range of temperature controllers, they are available with varying options just like the controller mentioned in the thread. There are drivers available in this forum and the NI web site for the devices.
http://www.eurotherm.com/
There is also OPC support and the diagnostic software available from Eurotherm is good.
But if a device has a specific manufacturers controller on it I might select one from the same family. Often I look around the plant / factory and see what models are in use. Using a model / type that already in use makes it easy for support in the factory and reduces support calls!
Hope these thoughts help out.

Scripting an interactive labview VI

I have a large top-level VI that controls and performs data collection for many different devices and over different interfaces. I currently do all of the control interactively through the front panel UI. I would like to have my VI be able to run off a script... not an external scripting language, but something like the Setpoint Profile VI's that come with the PID control toolset.
So obviously, implementing the Setpoint Profile VI's for my temperature controllers is pretty trivial. My problem is that I have many other devices which aren't necessarily controlled the same way. For example, for PID temperature control, you would just continually set the setpoint at a given interval, but for RS232-controlled pump, you would onl
y want to send a signal to stop or start it. I would like to have the scripting be a feature of the existing interactive VI (so I can toggle between automated and manual modes with a switch), and hopefully not have to have completely separate code.
So bascially I am wondering if anyone has a good strategies or examples for doing such a thing. Here are some issues I can think of:
- is it better to have one huge script that has the settings for all devices, or should I have separate scripts and synchronize them?
- I was considering scripting the UI itself, kind of like a "ghost user" using property nodes, but recent discussions on this board tell me this is not very efficient.
- are my expectations realistic?
thanks in advance for any advice.

Hi,
I think that you should implement a similar idea to the SetPoint Profile VI. One of the inputs to this VI is an array of clusters where each cluster has the time-value pair (setpoint). One approach would be to change the cluster to contain time and values for each device you are trying to automate. For example, you would have time, value for the temperature control, value for the pump and so on. Since the value for the pump would be on and off, you would want to have three values: ON, OFF and IGNORE(do nothing to pump at this time). Having an array of cluster with each cluster containing time and values for all your devices will allow you to synchronize the flow of your application since the time value will be common for all the devices.
Good luck
with the application. I hope this helps.
Sincerely,
Feroz

How to use the pid vis with a two-state output

Hello
Could someone tell me how to regulate the temperature of a room with
a two-state heater (on/off), using the pid vi's.

In <[email protected]> [email protected] (Helmut Hullen) writes:

^^^^^^ ^^^^^^^ ^^^^^^^
Frankly, I tend to agree. However, if you _need_ PID control and _if_
your two-state heater is solid-state switched, there are other
options. For example, commerical PID temperature controllers with
zero-voltage switching (ZVS) operate by generating a slow enabling
pulse, then achieving proportional control by varying the duty cycle of
this enabling pulse. For instanance, if your enabling pulse is running
at 10-Hz, with 50% duty cycle,
then your heating element will be on for
50% of the time every 0.1 second.
You can use a programmable timer (National includes two on their MIO
cards) to program the 5 or 10 Hz output and its duty cycle. You might
have LabView execute the PID subVI once every two or three seconds to
adjust the duty cycle on the programmable timer so as to minimize the
feedback error=(tempSetPoint-currentTemp).
Why are you wanting to use LabView for PID temperature control in the
first place? There are some very good PID temperature controllers
(programmable through a serial port) with built-in solid-state ZVSs
and readouts for $900 that you can buy. They'll fit right into
a control panel, display and all. Sure beats messing with a
programmable timer card and its outputs, plus you get a digital panel
readout to boot.
