PC Setup To use a 1:1 link, the only settings necessary are the communications mode and
the link words. Set the communications mode for one of the PCs to the 1:1 mas-
ter and the other to the 1:1 slave, and then set the link words in the PC desig-
nated as the master. Bits 08 to 11 are valid only for the master for link one-to-one.

DM 6645: RS-232C port
Link words for one-to-one link

2: LR 00 to LR 16
Port settings
00: Standard communication parameters
Communications Procedure If the settings for the master and the slave are made correctly, then the one-to-
one link will be automatically started up simply by turning on the power supply to
both the C200HSs and operation will be independent of the C200HS operating
modes.
Application Example This example shows a program for verifying the conditions for executing a one-
to-one link using the RS-232C ports. Before executing the program, set the fol-
lowing PC Setup parameters.
Master: DM 6645: 3200 (one-to-one link master; Area used: LR 00 to LR 15)
Slave: DM 6645: 2000 (one-to-one link slave)
The defaults are assumed for all other PC Setup parameters. The words used
for the one-to-one link are as shown below.
