S Possible bit allocations
Since all the CVM1/CV-series special auxiliary relays are allocated to the system,
they cannot be used for applications not related to the system.
The range of each memory area differs according to the PC type. See “Appendix L
PC Memory Map” (page 278 of the APPENDICES) for more details.
When making a data memory (DM) specification, specify the bit number (00 to 15)
following the word number.

The touch switch notification operations are as follows:

In the case of (3) and (4), the notification operation has no influence on the other

Notify bits and lamp bits for touch switches can be allocated to the areas of the
