Set top address of flag area

File address: OCT (octal), word

File number/flag: HEX (hexadecimal), byte

Set the top address of the flag area (24 bytes) in order to monitor the communication condition and PC operation condition on the parameter address 007764 to 007767(8).

Flag area uses 24 bytes regardless number of connecting stations.

007764(8)	Lower
007765(8)	Upper
007766(8)
007766(8)	File number
007767(8)		00(H): Do not output flag


		80(H): Output flag

-In case of setting ｺ 0740 (file address 000740(8)), "output flag" in parameter address 007764 to 007767(8). (Example for page 11-10)

(Word display)

Write "000740(8)" in parameter addresses 007764 to 007765(8).
