Tasks
FC CAM_INIT initializes the following data in the channel DB:
● The control signals
● The checkback signals
● The trigger, done and error bits of the jobs
● The function switches and their done and error bits
● Job management and the internal buffers for FB CAM_CTRL
Call
The function must be executed after a startup, i.e., after the power supply to the module or
CPU is switched on. You should therefore insert it, for example, in the restart OB (OB100)
and the removal/insertion OB (OB83) or call it in the initialization phase of your user
program. This ensures that your user program does not access obsolete data after a CPU or
module restart.
Call parameters
