Hi all
this is more a point of "I would like to Know"
I have been developing my Modbus interface and have had many hair pulling moments.
my latest is not understanding the update times of brains UserLed's
attached is a bit of code that detects if the Modbus link has been lost and E.Stops if it has
the DRO 1042 and 1043 update immediatly and using a DRO for logic 0 or 1 seems to work
They were in many attempts UserLed's
I tried for ages to use UserLed's expecting once set they could be read as a binary flag
but they would be in state "1" on one line and on the next would be state "0" and visa versa
can anyone tell me the rules on UserLed's
many thanks
