Programming the fail-safe control

In this example, the safety program in the F-CPU is executed in the fail-
safe FB1 function block. In order to clearly show the functions, a simple
program sequence was selected. Please refer to the appropriate function
examples and the manuals for Distributed Safety when complex safety
logic functions are involved as well as a list of the limitations/constraints
when writing the safety program.
Description
Make the following settings in the
menu bar under Options/
Edit_Safety program/ F_Run-time
groups:
– F_CALL: FC1
– F_PROGRAM: FB1
– IDB_F_PROGRAM: DB1
– CALL in: OB35
– Max. cycle time: 200 ms
– Call time: 100 ms
Then generate the safety program
and download to the module.
