  1. CX-Configurator - Profibus DP-V0

    Once again. I'm still facing problem with Pofibus communication between PLC and Comnet-DP module. I'm trying to connect Bosch valve station equiped with Comnet-DP communication module with Omron CJ2M and RPM21 (profibus master) I've made proper configuration in master settings (most important was baud rate but Bosch module adjust baud according to master) Then I've set slave configuration as you can see below: According to:   Other settings were unable to modify or just were left unchhanged. Omron is detecting connected slave but returns diagnostics that says that something is wrong in parameter settings. Same message I can read from Bosch module LEDs. Any experiance in profibus diagnosis, advices what to do? I've checked all settings configurations I have no idea what to do.        
  2. Hey guys,   I have worked on the FTView ME platform many of times.  I am now working on a FTView SE (Local Station) application, and I am having trouble connecting an Offline .ACD file to my program so that I can design.   If someone could help me with this it would be greatly appreciated.   Thanks in advance!
  3. So, hello all. I'm new in Omron PLC. Using: CP1L-EM controll + CP1W-TS102 (x3) Problem: I need to regulate the valve with motor drive. You can meet the same in heating system for control the temperature of water. Logic is simple,  - low temperature? - open valve step-by-step - high temperature? - close the value step-by-step I always use PWM regulation, but in Omron PWM only for encoder (srsly, i don't need 10k impulses during short period of time, i need just several impulses during the time) So, i decided to use TPO. The input calue for TPO is output value from PIDAT. (W451 manual, description of TPO function, example) What's the problem?  1. I need to make difference time between impulses.  Look here: I have 55 C temperature of the water, but i need 80 C, so i need impules for 8-10 sec duration, but when the temper close to 75-79 degress i need the impuls 1-2 sec duration. And, as i read, TPO cant do this, right? Just constant duration in 1 TPO instruction, or use several TPO instruction. Other situation, i have 80 degree Celsius, but i need 50 C, so i need to close the valve.  But i have only 1 TPO! So i need to check the difference beetwen SP (set point of temperature) and PV (process value) and if it hegative - go to PIDAT #1, which connected with TPO #1 and close the valve (SP-PV need to be around 0) If i have positive value (SP-PV) i need to go to PIDAT #2 wich connected with TPO #2.....  Srsly? I cant make the measure between -100 .... 100 for 1 TPO function and use 2 digital output?  I know that 0...10v regulation is better, but i have that i have =)   Sincerely, p001p
  4. Control Valve

    Hi, Please I am new to PLCs & SCADA. I will appreciate if someone can explain what it means by The inlet valve will be actuated by the SCADA  system via two 24V DC digital outputs. Why is it using two 24V DC digital output. Is this because it is a solenoid two way valve?   Thanks
  5. Triconex work station

    Dear Friends I have new job in next week , this job required logic modified for Triconex work station , they have some problem with some logic loops , I worked before with Simatic S7 V5.5 & Rockwell automation RSlogix5000 & RSlogix500 , FTV & Wincc I needs your help to know more about Triconex work station & Tristation 1131 , did I can get the software  then I can get some training before starting my job  Waiting your kindly help   Best Regards Ali
  6. Help Programming a Beckhoff PLC

    I have a very simple problem that I need help with.  I have some programming experience but I am brand new to PLCs and structured text.  I am using TwinCat 3 to program a Beckhoff CX9020.  My goal is to read the temperature from my thermocouple and open or close a valve based on the temperature.  I have successfully connected the PLC to the TwinCat software and I am able to see the value of the thermocouple increase and decrease when I touch it with my fingers.  I need to link that value to a variable in my code so I can have the valve act on it.  I don't know how to properly address the inputs and outputs.  Thank you!
  7. SIEMENS S7 STATION

    Dear All, I am very new to S7 PLC programming (S7 Simatic Manager v5.5) and I wanted to know how to back-up a system consisting of multiple PLC Stations (S7-1200, S7-300, etc). I am able to upload station to PG but that will save only per station. How about saving the whole system? I am not sure if i am using the right terminology. As you can see, I was given a zip file for the S7 project and it contains the whole system. I am trying to see how the commissioning engineer was able to do it (don't ask why I am not asking him instead). How can I then use this project file to download the program to the PLC/system once I decide to restore. I am at loss and have been searching for references over the internet. Uploading and downloading per station is no problem. I cannot seem to know how to do it on multiple stations system. I hope I have made some clear question or somehow you have managed to understand it.  TIA.
  8. Hello, I am having troubles configuring my Data Station Plus to be able to read my Vacon VFD registers over a Profibus network. The network is configured from an Omron PLC. I have communication but i do not know how to map the tags on Crimson to be able to read what the drives are doing. I am most likely thinking my offset on the tags that i have set are the main problem. Any input/ suggestion would be great thanks Specs on System: -Omron PLC CJ2M w/profibus PRM21 -Omron HMI NS-12 -3 Vacon NX VFD's -Data Station Plus w/profibus module
