2.3.5 Digital Outputs (DO-8203)
The following circuitry variants are examples, and do not relate exclusively to the depicted
inputs/outputs.
Note
The module is monitoring autonomously the communication to the master control element. With communi-
cation failure (> 150 ms) the parameterized failure behavior (terminate or keep) becomes active.
Further information see section 6.2.3, Behavior of the Process Outputs upon Startup and Failure.
