Replace Serial Masters with Ethernet Master(s), Slave IDs
are Fixed
Some legacy Modbus slave devices have fixed IDs that cannot be changed. In order to integrate the
devices into a Modbus TCP network, a multiport MGate model (MB3280, MB3270, or MB3480)
can be used to assign virtual slave IDs. For more information about virtual slave IDs, please refer to
Chapter 9.
Keep Serial Master and Add Ethernet Master(s)
In this scenario, the serial control system is a direct, low-latency system. The serial master must not
be replaced, but Ethernet masters will need to have access to the serial slaves for monitoring or
supervision.
