MODBUS Command Reference

modbusadd id Serial m (add a MODBUS serial slave)

Adds a MODBUS Serial Slave

id = 1 to 247 MODBUS ID

m = a or A ASCII transmission mode

m = r or R RTU transmission mode

Notes:

The MODBUS slave gateway will use the serial port settings configured using the port command

for all serial slaves.

For MODBUS RTU configuration to function properly d = 8 must be entered for the port

command. (This configuration is in accordance with the MODBUS specification)

modbusadd will return “Invalid IP address (Sx)” followed by an “OK” if modbusadd is configured

with parameters missing or incorrect parameters. Ensure that the modbussadd parameters

match those from the above list.

All MODBUS serial slave devices connected to a serial bus configuration such as RS485 must use

the same transmission mode. (This configuration is in accordance with the MODBUS specification)

cmd modbusadd 1 192.168.100.122 add TCP slave with ID 1 and IP 192.168.100.122
