Can a Modbus protocol be used to communicate between a Micrologic and a TSX PLC?

Yes, Modbus communication is possible between a Micrologic and a TSX PLC.  For an NT, NW or compact NS 800 to 3200 plug-in circuit breaker, the data tables are divided into 4 managers (3 for a fixed circuit breaker).

The four addresses (or the 4 slaves with linked addresses) are:
  • @ xx for the circuit breaker manager
  • @ xx +50 for the "chassis" manager
  • @ xx +100 for the "protection" manager
  • @ xx +200 for the "measurement" manager
Example:  A circuit breaker configured with address 21 has the circuit breaker manager at address 21 and the measurement manager at address 221, etc.  For communication with a PLC, the module used must be capable of managing the addresses up to 247.
