Status Functions
The status functions available via Modbus are listed below. The registers are accessed using Modbus func-
tion 1. Status labeled with an “L” after the Access types are latching type status. A latching status provides a
“since the last read” type status 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 status will reflect the current state.
