Alarm Functions
The alarm functions available via Modbus are listed below. The registers are accessed using Modbus
function 1. All the alarms are latching and provide a “since the last read” output where a set condition will
hold it’s state until a read of that particular register was made by the master device. Once a read is made,
the alarm will reflect the current state.
