    Hello everyone I'm new to omron plc . I have a system which consists 

    1. Omron Plc CP2E

    2. Two stepper motors and their drivers. 

    3. 4 Inputs-  one stepper start push button, second stepper go back push button, third stepper 1 home sensor, fourth stepper 2 home sensor

    4. 4 Outputs- stepper 1 step(-) Q 100.00, stepper 1 dir(-) Q100. 02, stepper 2 step(-) Q100. 01, stepper 2 dir(-) Q100. 03

    Seuence is like that:-

    Initially both stepper motors are at their home sensor. 

    When start push button is pressed both stepper move 110 mm distance and then stop. 

    Now when go back push button is pressed both stepper motors should go back to their home sensors and should stop at reaching their hone sensors. 

    This is the sequence. Can someone please send me the program by writing in cx - programmer or upload the photos of ladder program and settings also. Please

    It shows SPECIAL UNIT ERROR ERROR NUMBER 41.

    And there is one more thing in this system there is one special card A1SJ71AT21B WHOSE run, receive, send led never lit but the system works fine . Whenver plc is turned off and then turned on it always shows error in cpu and then after resetting the cpu it works normal. But even the send receive and rund led does not lit in A1SJ71AT21B card as you can see in the above photos I posted.

    I read both parameter and programs , but there was no information in I/0 assignment. You should take a look at step number from 466-579. It is a program of A1s68ad card which is already installed in the rack .

    Hi

    Direct addressing from the GOT to the point table is the way to go.

    Yeah i have checked the transmitter with some other temperature controller it gives the correct readings . I want to ask that when the transmitter is connected to A1S68AD CARD why does it show -2400 value .

    Hello. I have a system in which an A1S68AD card is used, that card has been damaged . I replace that damaged card with the new A1S68AD card with same wiring and same setting of dip switch. But at channel number 3 there is a RTD connected which gives 4-20 mA signal. But in Plc at channel number 3 the data register is showing -2400 fixed value all the time and in actual the temperature is varying. But PLC SHOWS FIXED VALUE OF -2400. PLEASE HELP ME OUT.
