Table C-5. Parameters
MULTIPLE DISCRETE
INPUT BLOCKS
The MDI block makes available for the FF network eight discrete variables of
the I/O subsystem through its eight output parameters OUT_D1/8 Status
indication in the OUT_Dx output parameters depends on the I/O subsystem
and the transducer block, that is manufacturer specific.
For example, if there is individual detection of sensor failure, it can be
indicated in the status of related OUT_Dx parameter. A problem in the
interface to the I/O subsystem can be indicated in the status of all OUT_Dx as
BAD – Device Failure.
