Section 5-1
As the number of the numeral table is written, the PT status numeral setting
strobe flag is simultaneously set ON (1). After this is notified to the PC, this flag
reverts to OFF (0). Checking the status of this flag will provide a simple method
of checking if a number has been input from the NT600S.
Note that this function is not available with the character-string memory table.
PT status (refer to page 197)
The NT600S operation status and other information are written with the ON or
OFF of the bits as shown below.

Since the special auxiliary relays of the CVM1/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 notify area must be set for each con-
nected PT.
