Once a Modbus port is activated by the Modbus selector command, the 2301D-ST will accept an external network master device. This allows a Modbus compatible device to monitor and perform all 2301D-ST mode parameters and commands to use a 2301D-ST port it must be configured properly.

Monitor Only 

The Modbus communication port, as defaulted from the factory, is not programmed. Although this port is not programmed it continue to update all information to all registers. This allows the 2301D-ST to be monitored but not controlled from an external device. By simply connecting a monitoring device, configured to communicate through Modbus, and to the 2301D-ST’s defaulted protocol settings (parity, stop bits, etc.), this device can be used to monitor all the 2301D-ST’s controlling parameters, modes, etc. without effecting control. To use a 2301D-ST port it must be configured properly.
