M880 Monitoring Channels' Logic

Structure byte 10

Read/Write

This value tells the M880 how to determine an exception.
This can be read or set using the table below.
Value
1     = Any 1 of the specified measurements causes an exception
2     = Any 2 of the specified measurements causes an exception
3     = Any 3 of the specified measurements causes an exception
128 = The SUM of the specified measurements causes an exception
129 = The AVERAGE of the specified measurements causes an exception

Internally the M5xx sets the maximum number of permissible parameters for the system’s mode of operation,
i.e. single phase, three phase three wire, three phase four wire or single phase three wire,so entering a value that's not applicable to the system will result in a default being used.
