Since the special auxiliary relays of the CV series PCs are allocated to the system,
they cannot be used for purposes other than the system use.
Set so that there is no overlap between the PT status control area and PT status
notify area. Otherwise the system may operate unpredictably.
When NT link (1:N) is set, the PT status control area must be set for each con-
nected PT.
