MODBUS SLAVE ADDRESS
Range: 1 to 254 in steps of 1
Default: 254
This setting specifies the Modbus slave address . Each device must have a unique
address from 1 to 254. Address 0 is the broadcast address to which all Modbus slave
devices listen. Addresses do not have to be sequential, but no two devices can have the
same address or conflicts resulting in errors will occur. Generally, each device added to
the link should use the next higher address starting at 1.
Please refer to the
3 Series Communications Guide
for details on how to set up the Modbus
communications protocol.
