Siemens SINUMERIK MC User Manual

Procedure
Proceed as follows to implement a user acknowledgment for global reintegration:
1. Insert operation "ACK_GL" in that F-runtime group, whose F-I/O should be globally
acknowledged by the user acknowledgment.
2. In operation "ACK_GL", assign input "ACK_GLOB" to the input of the acknowledgment
button.
3. If necessary, carry out the optional steps:
Setting Procedure
Evaluation of the acknowl‐
edgment request
You can evaluate the F-I/O DB tag "ACK_REQ" in the standard user
program or on an operation and monitoring system, to interrogate as
to whether a user acknowledgment is required.
● ACK_REQ = 0: No acknowledgment request
● ACK_REQ = 1: Acknowledgment request for reintegration (this is
set by the F-system after the fault has been resolved)
Controlling a signal light or
output of a signal
In the case of a fault, you can control a signal light and/or output
messages/signals in the standard user program, by evaluating the
following:
● F-I/O DB tags:
– QBAD
– DIAG
● Diagnostics buffer of the F-PLC
Automatic or manual reinte‐
gration for F-I/O/channel
faults
You can parameterize the F-I/O DB tag "ACK_NEC" if, after an F-I/O/
channel fault, automatic reintegration should take place without user
acknowledgment.
● ACK_NEC = 1 (start value): User acknowledgment required
● ACK_NEC = 0: Automatic reintegration
A user acknowledgment is always required after a communication
error.
Parameterizing tags ACK_NEC = 0 is only permitted, if, from a safety-relevant perspective
automatic reintegration is permissible for the process involved. (S010)
6.3.7 Acknowledging messages related to safety functions integrated in the drive
You program PROFIsafe acknowledgment in the safety program of the F-PLC by setting the
"Internal Event ACK" signal - separately for each drive object - via the PROFIsafe telegram
(S_STW1/S_STW2 bit 7).
Safety messages cannot be acknowledged collectively by the F-PLC, but instead have to be
individually acknowledged for each drive object. A falling edge of the "Internal Event ACK"
signal resets the status "Internal Event" in the particular drive, and thus acknowledges the fault.
