Slave IP Address
Type in the four octets of the IP address of the slaves being addressed.
• If you configure the last octet as 000 the MES1A/B will use the Slave
Address/Unit ID of the slave as part of the IP address. This allows a
Modbus/RTU master (connected through the MES1A/B) to access up to
255 remote Modbus TCP slaves.
• If you configure the last octet for a number between 1 and 254, all slave
polls in this group will be sent to the same IP address.
