Passivation and Operator acknowledgment of the measuring system
9.4.1
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 PROFIBUS-DP, 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".
9.4.2
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" .
