The Auxiliary Area of the CVM1 and CV-series PCs is allocated to system func-
tions, and it cannot be used for purposes other than system use.
The range of each memory area differs according to the PC. Refer to Appendix D
PC Memory Maps on page 435.
When a DM Area or EM Area address is specified, add a bit number (00 to 15) to
the end of the word address.
Lamps read the contents of a bit at the host and execute processing in accor-
dance with the bit status.
However, the bit is only read in the following case:
When a lamp is used on the currently displayed screen
Lamps have no output function.

were registered on the screen with the Support Tool. However, the way in
which they overlap can be changed with the Support Tool.
