Hi DI 880 Card as such doesnt have loop monitoring functionality.
Loop supervised DI functionality can be accomplished by configuring AI880/AI880A for the function Loop supervised digital input.
When used as Loop Supervised, the I/O module can handle input signals with defined levels for open circuit, logic low state, logic high state, and short circuit.
When using the function, Loop Supervised DI, the for parameter settings and field loop arrangement (resistor network) please refer the manual
3BSE020924-510 A and seaction AI880/AI880A High Integrity Analog Input Module where resistor values are mentioned.
