Passivation And Operator Acknowledgment Of The Measuring System; After Start-Up Of The F-System; After Communication Errors - TR-Electronic AD 582 Serie Gesamt-Bedienungsanleitung

5.4 Passivation and Operator acknowledgment of the measuring system

5.4.1 After start-up of the F-System

After a start-up of the F-System, the communication between F-CPU and measuring
system via the PROFIsafe protocol must first be established. A passivation of the
measuring system occurs during this time.
During use of the substitute values (0), the variables QBAD, PASS_OUT, QBAD_I_xx
and QBAD_O_xx = 1.
The operator acknowledgment of the measuring system, i.e. the output of cyclical data
at the fail-safe outputs, automatically occurs, from the viewpoint of the F-Host,
independently of the setting at the ACK_NEC variable, at the earliest from the 2nd
cycle of the F-Runtime Group after start-up of the F-System. Depending on the cycle
time of the F-Runtime Group and the PROFINET, the operator acknowledgment can
only occur after a few cycles of the F-Runtime Group.
If the establishment of communication between F-CPU and measuring system takes
longer than the monitoring time set in HW Config in the Object Properties for
the F-Periphery, no automatic operator acknowledgment occurs.
In this case a positive edge of variable ACK_REI of the F-Periphery-DB is required,
which is linked to the input of the digital input module --> I 16.0, symbol name:
"RESET".

5.4.2 After communication errors

If the F-System detects an error in the safety-oriented communication between the
F-CPU and measuring system via the PROFIsafe protocol, a passivation of the
measuring system occurs.
During use of the substitute values (0), the variables QBAD, PASS_OUT, QBAD_I_xx
and QBAD_O_xx = 1.
The operator acknowledgment of the measuring system, i.e. the output of cyclical data
at the fail-safe outputs, only occurs if:
● no further communication errors are present, and the F-System has set the
variable ACK_REQ = 1
● an operator acknowledgment with positive edge of variable ACK_REI of the
F-Periphery-DB has occurred, which is linked to the input of the digital input
module --> I 16.0, symbol name: "RESET"
