MD21220 $MC_MULTFEED_ASSIGN_FASTIN = <byte address>
<byte address>
Note
Multiple assignments
Multiple assignments of inputs are not considered to be incorrect parameterization.
Multiple assignments of outputs are considered to be incorrect parameterization, are checked
during run-up and indicated by an alarm.
Example: Hardware assignment of external I/Os
Two input bytes and one output byte are parameterized for the reading/writing of digital I/Os
of a PROFIBUS module.
Number of active NC I/O bytes
