Not sure if this is the right place to post this, but it's almost certainly related to the "one off" "feature" of modbus / Siemens. I'm writing to a Logo PLC version 8.3 via our scada system, I'm then reading those values with a CMR2040, unfortunately, for me at least, the System writes in word format , i.e. 16 bits, while the Logo is Byte size, I know a 16bit is 2 bytes and a DWord is 4 bytes, If I write to a single word it alters three registers in the CMR, depending on the value, one of them might be the correct value until it increases. Is there a way around this, I've not mapped any registers, as I was hoping to use default values. It could be a CMR issue reading from the wrong starting point. ------------------------------------------------------------------------------------------ |
