Enabling axis--specific SI functions
This means that the safety functionality in these systems is not activated and they
behave neutrally.
Correct operation of the general NC functionality is guaranteed (start and protec-
tion of the SPL program does not have a disturbing effect). However, the safety
functionality implemented in the application (i.e. not within the context of the simu-
lation) is not corrected. Influencing the part program sequence by querying safety
system variables or querying the above--mentioned enable machine data is not
changed.
Simulation, machine integration
For these systems (Windows--based with simulated PLC), the complete safety
functionality (axis motion monitoring), PROFIsafe and F_SENDDP/F_RECVDP
coupling should function just the same as in a real system.
The safety functionality can be parameterized and programmed just the same as in
a real control system. The communication mechanisms on the PLC side ensure
that the PROFIsafe and F_SENDDP/F_RECVDP protocols are maintained. Exter-
nal software components can read--in or read--out net data in/out of the PROFIsafe
module adapter.
