Connecting to a Node
C200HX/HG/HE PCs Use the PC Setup (DM Area) of the PC to set the communications parameters
for the port to be used (peripheral port or RS-232C port.)
Note When DIP switch pin 5 on the CPU Unit is set to ON, the communications param-
eters are set as follows, regardless of the PC Setup:
Communications:
Node No.:
Start bits:
Data bits:
Stop bits:
Parity:
Baud rate:
Transmission delay: None
Setting Standard Communications Parameters
RS-232C port: DM6645
Communications mode
Set to (0: Host Link)
Not related when Host Link is set
CTS control (Yes/No)
Communications parameters
0: Standard communications parameters
1: According to DM 6646
Initial status: 0000 (Standard communications at 9,600 bps.)
Bits 8 to 11 are valid for only the master node with 1:1 link.
Bits 0 to 7 and 12 to 15 are valid only when DIP switch pin 5 on the CPU Unit is set
to OFF.
The standard communications parameters are as follows:
Start bits: 1 bit
Data bits: 7 bits
Stop bits: 2 bits
Parity: Even
Baud rate: 9,600 bps
Always set the mode to be used.
If the above communications parameters are acceptable, specify 00 in the lower
two digits.
Setting Communications Parameters
The Controller Link Support Software can communicate with PC only when DIP
switch pin 5 on the CPU Unit is set to OFF and DM 6645 is set to use DM 6646
settings.
RS-232C port: DM 6646
