Digital Inputs/Outputs (Job No. 101)
Four digital inputs and four digital outputs of the FM 453 can be used specifi-
cally to a given application.
The conventions and parameterization for this purpose are defined in the ma-
chine data MD34 to MD36.
The signals are processed in the FM cycle.
The signal status of the digital inputs and outputs can be recognized by read-
back (job no. 101).
Table 9-13 shows you the functions assigned to each digital I/O.
