Dears,
I'm working with Premium Hot/Standby PLC to communicate with Sub-systems via Serial Modbus. I use READ_VAL & WRITE_VAL function blocks to exchange the data with those sub-systems. the problem here that I can only exchange %m & %mw data types which equivalent to 00XX & 40XX registers, do any body know how can I exchange Registers 10XX & 30XX? I've worked in a similar project before but with M340 Processor and I was able to read/write registers 10XX & 30XX by using %I & %IW data types but it doesn't work now with premium Hot/Standby processor. Any idea?
