Communications Settings
(DM 6646 and DM 6651)
The settings in DM 6645 and DM 6650 determine the main communications
parameters, as shown in the following diagram.
DM 6645: RS-232C port
DM 6650: Peripheral port
Communications mode
0: Host Link
1: No-protocol
2: One-to-one data link slave*
3: One-to-one data link master*
4: NT Link in 1:1 mode*
Link words for 1:1 data link*
0: LR 00 to LR 63
1: LR 00 to LR 31
2: LR 00 to LR 15
CTS control settings
0: Disabled
1: Enabled
Port settings
0: Standard communication conditions
1: According to setting in DM 6646, DM 6651
Default (0000): Host Link using standard parameters, no CTS control
Note
*These settings can be made for the RS-232C port (DM 6645), but
not for the peripheral port (DM 6650).
When pin 5 of the CPU Unit's DIP Switch is OFF and the settings in DM 6646
(or DM 6651) are enabled in DM 6645 (or DM 6650), these settings determine
the transmission frame format and baud rate, as shown in the following dia-
gram.
DM 6646: RS-232C port
DM 6651: Peripheral port
Transmission Frame Format (See table below.)
Baud rate (See table below.)
Default: Standard communication conditions.
