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.
