Acknowledging the diagnostic message
After acknowledging the diagnostic message, the current state at the input is immediately
transmitted to the controller.
If required, implement a startup inhibit in the application program following error acknowl
-
edgment.
6.2.5
Cross-circuit detection
Cross-circuits with other inputs are only detected if cross-circuit monitoring is enabled.
If all inputs are parameterized without cross-circuit monitoring, the clock outputs provide DC
voltage without clock pulses. As soon as cross-circuit monitoring has been parameterized
for at least one input pair, pulses are output at clock outputs OUT_T1 and OUT_T2.
For inputs that are parameterized with cross-circuit monitoring, the assignment is as follows:
– Inputs for channel 1 (INx_CH1) are assigned to clock output OUT_T1.
– Inputs for channel 2 (INx_CH2) are assigned to clock output OUT_T2.
The cross-circuit error results in the transmission of the safe state in the process data image
of the affected inputs.
Please observe the error detection time.

“Error detection time” on page 23
