Entering the Slave Address
The slave address is a setting used in Modbus
®
communications. It is a number that ranges from 1 to 65535,
excluding 252 to 255 and 64764. If the Modbus
®
request message contains the matching address, the
device will respond to the request. In network arrangements, the device must have a unique slave address.
For more information about Modbus
®
communications, refer to the protocol manual section. If Modbus
®
communications are not used, leave the slave address at the factory setting (1).
