  1. Sorry my mistake, I did like you advised for a start, but then I started to suspect everything and that's why I added these linear functions. The Idea was that the MI:s are then used once in a program, I could also try overight the MI's but I couldn't. When I sent the program to you I changed the MI-numbers back to original, but forgot to delete the linear function's. So this wasn't the solution for me, I hope there is some misstake as simple as that in my project, but I cannot figure it out. I cannot understand, because It should be simple to get value from my expansion modules to a my HMI. Maybe this is still some kind of version problem. The PLC/HMI is unused and not so old, but my expansion modules might be very old, IO-ATC8 is V3.00, but at EX-A1 and V1040 doesn't have any version numbers. But then again V1040 it seems to communicate with V1040. Only the reading is allways maximum.
  2. Sorry, it wasn't a right file but this is, thank you for your time. http://forum.unitronics.com/index.php?/files/file/45-juho-salminen/
  3. Version v2

  4. Can you open my project file from here http://forum.unitronics.com/index.php?/files/file/44-io-atc8/

  7. And yes the communication light goes on in both EX-A1 modules, the Run light goes on at the io-atc8. And I recently tried to test PT4-module but its run light only flashed.
  8. This might be the problem, I don't have EX-A2X module, does it have any restrictions with io-atc8. I mean if I have older io-atc8 module and new EX-A2X, should they be combatible or is there any restrictions related to io-atc8 versions and EX-A2X.
  9. Okay, I started to suspect everything, -So I placed io-snapin module in the back of my V1040 PLC and tested one analog voltage input with 1,5 voltage battery and it worked like it should. -Then I changed my io-atc modules first two analog inputs to voltage mode with two jumpers and connected the 1,5V battery in its terminals and no success. -After this I tried to change EX-A1 module to a another one and nothing changed -Then I changed PLC to a Vision 120, and still couldn't get anything else than maximum, from the channels. So do you have any suggestions how can I troubleshoot the io-atc module
  10. Thank you for your answers, I don't have any K-type cable's only one K-type sensor. My main goal is test everything in my workshop and then go to assembly it in the final destination, where i will connect the thermocouples. I am assuming that with these short wires I should get ambient temperature, not the channels maximum reading that I now do have. The one channel that I told is giving value 11460 is floating, so the value changes a little bit. Here is one post from moderator Joe T, according to this the shorted channel should give ambient temperature, the post is from this thread: http://forum.unitronics.com/index.php?/topic/1908-io-atc8-problem/?hl=thermocouple " The IO-ATC8 card is not isolated, and noise from the system can cause very odd behavior. The first thing to do is disconnect all the thermocouples from the card and replace each one with a short jumper (I use a cut off paperclip) across the thermocouple terminals. You should read ambient temperature on every channel. If you don't, there is something wrong with the hardware or the configuration. If you do read ambient, re-connect the thermocouples one at a time until the problem shows itself. "
  11. "You have to set DIP switches inside into right position." If you mean by dip-switches a jumpers that are mentioned in manual, so yes I have checked these jumpers they are all at B. "You have to add IO-ATC8 to PLC Hardware Configuration and configure Inputs as TC K. Then connect TC with a right polarity to IO-ATC8 terminals." The configuration should be as you mentioned. Now I have short wires connected to sensor terminals, but i have had also thermocouple connected and i tried to change polarity but it didn't have any effect. With short wires, shouldn't it show a module inner temperature. Any other ideas?
  12. Hello I have a problem with thermocouple sensors, I get value of 32767 for seven of my inputs and 11460 for one of my input. Do you have any Ideas of what can i do about it? How can I have proper temp values for my PLC? I'm intending to get temperature trends and numeric variables for my HMI. What I have allready done: - disconnected all my sensors and have a short wires connected in every channel - changed the io-atc8 module's internal jumpers to B selection - changed hw-configuration for all input channels to K-type and variables from MI100-107 PLC: Visilogic 1040 Modules: EX-A1 - expansion adapter IO-ATC8 - 8-channel analog input module Sensors: Thermocouple K-type
