Description
COP_MSTR_MAIN must be cyclically executed in the program.
This generates the SYNC object for the connected slave
modules. The network is monitored at the same time. If a slave
fails, the number of the node is entered in the array RESULT.
Thus max. 8 errors can be stored. They are entered in the order
of their occurrence. The error memory can be deleted again via
the function input RESET_GUARDING.
