6.2.5 Data Flow Between MVI56E-MCM Module and ControlLogix
Processor
The following topics describe the flow of data between the ControlLogix
processor,MVI56E-MCM module, and nodes on the Modbus network. Each port
on the module can be configured to emulate a Modbus Master device or a
Modbus Slave device, independently from the configuration of the other port.
Only the module database is shared between ports. The sections below discuss
the operation of each mode.
