All my various motor control bits and setpoints are mapped to holding registers in a Schneider PLC. I can read/write the setpoints fine. But I can only read the bits. Attempting to write to them causes an error.
Here’s a typical address
ns=1;s=[Acid Dosing PLC]HR201.8
And the error generated
Could anyone help me diagnose the error? Is it something I’ve messed up in Ignition or is it possible the Schneider doesn’t support bit writing in holding registers.
