DM 6629 00 to 03 PV coordinate system for pulse output 0
0: Relative coordinates; 1: Absolute coordinates
04 to 07 PV coordinate system for pulse output 1
0: Relative coordinates; 1: Absolute coordinates
08 to 15 Not used.
DM 6630 to 00 to 15 Not used.
DM 6641
High-speed Counter Settings (DM 6642 to DM 6644)
The following settings are effective after transfer to the PLC 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, 00 to 15 Not used.
DM 6644
RS-232C Port Communications Settings
The following settings are effective after transfer to the PLC.
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 PLC 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 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.)
