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.
Procedure 1. Use the support tool to allocate the PT status notify area (PT → PC) to the PC

meral memory table to the PC memory.

PT status notify area when the numeral setting strobe flag in the PT status
notify area comes ON (1).
4. Read the allocated word for the numeral memory table number read in step 3.
