High-speed Counter Settings (DM 6642 to DM 6644)
The following settings are effective after transfer to the PC the next time operation is started.
DM 6642 00 to 03 High-speed counter mode (Effective only when bits 08 to 15 are not set to 00.)
0: Differential phase mode (5 kHz)
1: Pulse + direction input mode (20 kHz)
2: Up/down input mode (20 kHz)
4: Increment mode (20 kHz)
04 to 07 High-speed counter reset mode (Effective only when bits 08 to 15 are set to 01.)
0: Z phase and software reset; 1: Software reset only
08 to 15 High-speed counter/Synchronized pulse control for IR 00000 to IR 00002
00: Don’t use either function.
01: Use as high-speed counters.
02: Use for synchronized pulse control (10 to 500 Hz).
03: Use for synchronized pulse control (20 Hz to 1 kHz).
04: Use for synchronized pulse control (300 Hz to 20 kHz).
DM 6643,
DM 6644 00 to 15 Not used.
RS-232C Port Communications Settings
The following settings are effective after transfer to the PC.
If CPU Board communications switch SW202 is ON, communications through the RS-232C port are governed by the
default settings (all 0) regardless of the settings in DM 6645 through DM 6649.
DM 6645 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 PC Link
0: LR 00 to LR 15 (Any other settings are ineffective.)
12 to 15 Communications mode
0: Host Link; 1: No-protocol; 2: 1:1 PC Link Slave; 3: 1:1 PC Link Master; 4: NT Link
(Any other setting causes a non-fatal error and turns ON AR 1302.)
DM 6646 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
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),
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.)
