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.
The range of respective area varies with the type of PC. Refer to Appendix L PC
Memory Map (page 291).
Procedure 1. Use the support tool to allocate the PT status control area (PC to PT) to the PC

ter-string memory table by using the support tool.
To display numerals, use “numeral display” and specify the numeral memory
table by using the support tool.
3. Set the copy source data to the memory table when creating the screen data
by using the support tool.
Use “table edit”.

number, and copy source memory table number to the “copy memory table”
setting word in the PT status control area.
