After completion of test stop step 2, marker 217.1 is set and the forced
checking procedure for the inputs is started. The forced checking procedure is
performed in the following sequence.

Note
If an EMERGENCY STOP is triggered during the forced checking procedure
of the input and outputs, automatic acknowledgement is interrupted and the
test step is terminated.
If an error occurred while checking the checkback input and EMERGENCY
STOP is actuated, acknowledgement is only possible after the error has been
removed (diagnostics) of the checkback input by the RESET button.
