A.3.2 Structure - Digital inputs status and digital outputs status with the function codes
0x01 and 0x02
The following are available via MODBUS:
●
"Digital Inputs Status"
● "Digital Outputs Status"
Input status and output status of the SENTRON PAC Power Monitoring Device
You can use the function codes 0x05 and 0x0F on the digital outputs in addition to the
function codes 0x01 and 0x02.
