I currently have a 230A that I am trying to get to work with the TTL serial output from an arduino based PLC. unfortunately I can't seem to get the checksum to work whatsoever.
in the user manual there is a reference to pre made libraries and examples for arduino based applications. however I can't seem to find any such examples on the website.
is there actually a prebuilt library? or any examples that I could reference.
also is the multi unit capability enable for rs232 operation?
