Monitoring time in the fail-safe DP standard slave/IO standard device/PA field
device.
A valid, current safety telegram must arrive from the F-CPU within the monitoring
time. This ensures that failures and errors are detected and the appropriate reac-
tions triggered to keep the safety system in a safe state or to transfer it to a safe
state.
If this option is activated, you have the capability of assigning the F-I/O DB-
number manually. Otherwise it is assigned by the F system.
Here you assign a number for the F-I/O DB.
The adjustable value range depends upon the value range for DBs set in the
Safety Administration Editor (area "Settings > Assign numbers for F-system
blocks"), or is automatically managed by the F-system.
The name of the F-I/O DB is displayed here.
The start address is part of the F-I/O DB-name of this telegram. If you change the
start address, the F-I/O DB-number will also be changed.
The F-I/O DBs are located at the following point in the project navigation: "Con-
troller (e.g. CNC_1 > PLC 1) > Program blocks > System blocks > STEP 7 Safety
> F-I/O DBs"
