Modbus Registers

The Modbus version of Sensepoint XRL allows interaction with the gas

detector using Modbus/RTU over an RS-485 physical layer. The

Modbus interface provides a means to monitor and interrogate the

detector with the addition of being able to reset alarms remotely. The

Modbus registers for Sensepoint XRL are given in the following table.
