(Other settings will cause a non-fatal error, the default settings (03) will be used,
and AR 1302 will turn ON.)
DM 6647 00 to 15 Transmission delay (Host Link)
0000 to 9999 (BCD): Set in units of 10 ms, e.g., setting of 0001 equals 10 ms
(Other settings will cause a non-fatal error, the default setting (0000) will be used,
and AR 1302 will turn ON.)
DM 6648 00 to 07 00 to 31 (BCD): Node number (Host Link)
(Other settings will cause a non-fatal error, the default setting (00) will be used, and
AR 1302 will turn ON.)
08 to 11 Start code enable (RS-232C)
0: Disable; 1: Use start code in DM 6649.
12 to 15 End code enable (RS-232C)
0: Disable (number of bytes received)
1: Use end code in DM 6649.
2: CR, LF
(Other settings will cause a non-fatal error, the default setting (0) will be used, and
AR 1302 will turn ON.)
DM 6649
00 to 07 Start code (00 to FF)
(No-protocol, effective when bits 8 to 11 of DM 6648 are set to 1.)
08 to 15
No. of bytes of data received
(No-protocol, effective when bits 12 to 15 of DM 6648 are set to 0.)
00: 256 bytes
01 to FF: 1 to 255 bytes
End code (00 to FF)
(No-protocol, effective when bits 12 to 15 of DM 6648 are set to 1.)
Word Bit
DM 6650 00 to 03 Port settings
0: Standard (1 start bit, 7-bit data, 2 stop bits, even parity, 9,600 bps; Host Link
1: Settings in DM 6651
(Other settings will cause a non-fatal error, the default setting (0) will be used, and
AR 1302 will turn ON.)
04 to 11 Not used
12 to 15 Communications mode
0: Host Link or peripheral bus; 1: No-protocol
(Other settings will cause a non-fatal error, the Host Link setting will be used, and
AR 1302 will turn ON.)
