5.2

Modbus Operation

When the PLX51-PBM has been setup for Modbus communication it will exchange
data with a remote Modbus device. Depending on the Primary Interface selection, the
PLX51-PBM will either function as a Modbus Master or Modbus Slave.

NOTE: When configured as a Modbus Slave the Modbus Master device will need to read and write all
required data from the configured Modbus address ranges. When configured as a Modbus Master the

PLX51-PBM will automatically update the required Modbus registers in the configured remote target.

5.2.1

PROFIBUS DP - Master

Once the PLX51-PBM and Modbus device have been correctly configured, the
PLX51-PBM will start exchanging data with PROFIBUS slave devices. The user will
need to set the PROFIBUS Operating mode from the relevant Modbus Mapping
Register.

Master and Slave Device Status

The Master Control command is set in Holding (HR) registers starting at the

Master

Control Register
