writing the scan list to the non-volatile
memory.
If there is an error in the slave scan
list, disable the slave function, reset
the allocations, and then enable the
slave function. Or, reset the slave
scan list with the CX-Integrator. If
there is an error in the master scan
list, clear the scan list, and then regis-
ter the scan list again. Or, reset the
master scan list with the CX-Integra-
tor.
