The jumber setting for CH4-5 was wrong at first and after changing it, I am getting the same error again. How can I solve this?(Please refer to Picture). 2-When I am online in the program, the analog PIW addresses do not react when the external 0-10 V or 4-20 mA values change, it always shows 0. However, I see the manipulated value at the FB output. Attachment 789.PNG (284 Downloads)

And how are they parameterized? 2. How do you check the PIW address? Try to use a Move instruction, to move it to a MW or DB.DW. What does it show? Best regards, Wizard
