DI expected states in table format:
Test stop state: Expectation Mode 1 / Mode 2 / Mode 3 / Mode 4
5: -/1/1/-
7: -/0/0/-
9: -/0/1/-
11: -/0/1/-
13: -/1/1/-
Example:
Fault F01773 (P1) is signaled with fault value = 0001_0127 and fault F30773 (P2) is signaled with fault value
0000_0127.
This means that in state 7 (Z = 7) the state of the external readback signal was not set correctly (Y = 2) after DO-0 (X
= 1) was switched to ON/ON.
Fault value 0001_0127 indicates that 0 was expected (W = 0) and 1 (V = 1) was read back from the hardware.
Fault value 0000_0127 on the processor 2 indicates that the states were as expected.
In the case of fault F30773, W and V are always identical; a value of 0 always means that 0 was expected at the
readback input but was not present on processor 1.
Remedy: Check the wiring of the fail-safe digital output (F-DO) and restart the test stop.
Note:
- the fault is withdrawn if the test stop is successfully completed.
- in the event of multiple test stop faults, the first one that occurred is shown. Once the test stop has been restarted
the next queued test stop fault will be signaled (if there is one).
F-DO: Failsafe Digital Output
A01774 SI Motion P1 (CU): Test stop for fail-safe digital outputs required
Message class: Safety monitoring channel has identified an error (10)
Reaction: NONE
Acknowledge: NONE
Cause: The time set in p10003 for the forced checking procedure (test stop) for the fail-safe digital outputs has been
exceeded. A new forced checking procedure is required.
After the next time the forced checking procedure is selected, the message is withdrawn and the monitoring time is
reset.
Note:
- this message does not result in a safety stop response.
- the test must be performed within a defined, maximum time interval (p10003, maximum of 8760 hours) in order to
comply with the requirements as laid down in the standards for timely fault detection and the conditions to calculate
the failure rates of safety functions (PFH value). Operation beyond this maximum time period is permissible if it can
be ensured that the forced checking procedure is performed before persons enter the hazardous area and who are
depending on the safety functions correctly functioning.

Remedy: Carry out the forced checking procedure for the digital outputs.
The signal source to select the forced checking procedure is set via binector input p10007.

A01788 SI: Automatic test stop waits for STO deselection via motion monitoring functions
Message class: Safety monitoring channel has identified an error (10)
Reaction: NONE
Acknowledge: NONE
Cause: The automatic test stop (forced checking procedure) was not able to be carried out after powering up.
Possible causes:
- the STO function is selected via safe motion monitoring functions.
- a safety message is present, that resulted in a STO.
Note:
STO: Safe Torque Off
