Communication, Counter and Pulse
SECTION 4
4-1 PLC-setup Communication
4-1-1 RS-232C Port Communications Settings
The following settings are effective after transfer to the PLC.
If pin 2 of the 3G3MV-P10CDT Unit’s DIP switch is ON, communications
through the 3G3MV-P10CDT’s RS-232C port are governed by the default
settings (all 0) regardless of the settings in DM 6645 through DM 6649.
Word(s) Bit(s) Function
00 to 03 Port settings
0: Standard (1 start bit, 7 data bits, even parity, 2 stop bits, 9,600 bps), Host Link unit
number: 0
1: Settings in DM 6646
(Any other setting will cause a non-fatal error and AR 1302 will turn ON.)
04 to 07 CTS control setting
0: Disable CTS control; 1: Enable CTS control
(Any other setting will cause a non-fatal error and AR 1302 will turn ON.)
08 to 11 Link words for 1:1 data link
0: LR 00 to LR 15 (Any other settings are ineffective.)
DM 6645
12 to 15 Communications mode
0: Host Link; 1: No-protocol; 2: 1:1 PLC Link Slave; 3: 1:1 PLC Link Master; 4: NT Link
(Any other setting causes a non-fatal error and turns ON AR 1302.)
00 to 07 Baud rate
00: 1,200 bps; 01: 2,400 bps; 02: 4,800 bps; 03: 9,600 bps; 04: 19,200 bps
DM 6646
08 to 15 Frame format
Start bits Data bits Stop bits Parity
00: 1 bit 7 bits 1 bit Even
01: 1 bit 7 bits 1 bit Odd
02: 1 bit 7 bits 1 bit None
03: 1 bit 7 bits 2 bits Even
04: 1 bit 7 bits 2 bits Odd
05: 1 bit 7 bits 2 bits None
06: 1 bit 8 bits 1 bit Even
07: 1 bit 8 bits 1 bit Odd
08: 1 bit 8 bits 1 bit None
09: 1 bit 8 bits 2 bits Even
10: 1 bit 8 bits 2 bits Odd
11: 1 bit 8 bits 2 bits None
(Any other setting specifies standard settings (1 start bit, 7 data bits; even parity, 2 stop
bits, 9,600 bps), causes a non-fatal error, and turns ON AR 1302.)
DM 6647 00 to 15 Transmission delay (0000 to 9999 BCD sets a delay of 0 to 99,990 ms.)
(Any other setting specifies a delay of 0 ms, causes a non-fatal error, and turns ON
AR 1302.)
00 to 07 Node number (Host Link)
00 to 31 (BCD)
(Any other setting specifies a node number of 00, causes a non-fatal error, and turns
ON AR 1302.)
DM 6648
08 to 11 Start code selection for no-protocol communications
0: Disables start code; 1: Enables start code in DM 6649
(Any other setting disables the start code, causes a non-fatal error, and turns ON AR 1302.)
