Doing my first Control Microsystems SCADAPack job and have to communicate with Square D Motor Logic Plus solid state overload relays. Not sure which SCADAPack ladder instruction (MSTR?) to use and how to address the overload?? HELLLLLPPPPPP.

We are using them to communicate with WAGO I/o via Modbus RTU. The info for talking to slave modules is in the examples subdirectory when the program is installed. This may give you the info you need. Hope it helps.

It appears to be the MSTR instruction,but nobody can tell me what "slave" registers (in the 40000 range, I presume) to identify in the MSTR instruction.
