  1. Hello,      I make a project where I should control temperature for thermoplastic extruder. I read for this type of process a two position controller is enough but I want to use a PID controller. I have values for P,I,D,Tf and I applied Z-transform and I have a numeric controller which is implemented through structured list.  I want to control heating element with this PID but my problem is I don't have an analogue output module just a digital output module(OD 212) and now my question is : How I can( if it is possible) to control duty of PWM with output from pid?  (I have a CJ2M processor)
  2. Controlling heater element with PWM

    I have also md211 module. I have this documentation : https://assets.omron.eu/downloads/manual/en/v3/w486_cj2m-md21_pulse_i_o_module_users_manual_en.pdf. I made a program like in picture but in cio 2961 , 2963 I don't see anything! Or where I can see this pwm signal?
  3. Hello,      I want to make an application to control a heater element . I have a thermocouple(k) , I read value from it with ad04u module and with od212 module I want to control the heater element with PWM. Now that's my problem , I don't know how to configure in cx-programmer to put on output from od212 pwm signal. I read in documentation about Pwm but is a poor explication about this problem. (I use CJ2M processor). What else conditions must to check for I can work with pwm signal?
  4. Hello      I have a cj2m processor and md211 module and I want to read position from rotary encoders who are put on the stepper motors. I use high speed counters to count the number of(I made settings like in documentation) but every time I read velocity.   In first two picture I have 3 blocks for PRV function , I set port specifier [#0, #1 and #3] because on this ports I command 3 axis. Please help me!
