4-4-1 Host Link Communications

When creating a 1:1 PC Link with a CPM2A/CPM2C PC, use a Programming
Device to make the following settings to the PC Setup (DM 6645) in the Master
and Slave.
Function
For information on the 1:1 PC Link settings of another OMRON PC, refer to that
PC's Operation Manual.
This section describes the RS-232C connection.
The RS-232C cable used for 1:1 PC Links is a cross connection cable. When
there is no CTS control on the RS-232C port, the connection is made as shown
in the following diagram. With the CPM2C, the CPM2C-CN111 and CS1W-
CN118 connecting cables are used.
RS-232C port
Signal Pin No.
Host Link communications were developed by OMRON for the purpose of con-
necting PCs and one or more host computers by RS-232C cable, and controlling
PC communications from a host computer. Normally the host computer issues a
command to a PC, and the PC automatically sends back a response. Thus the
communications are carried out without the PCs being actively involved. The
PCs also have the ability to initiate data transmissions when direct involvement
is necessary.
In general, there are two means for implementing Host Link communications.
One is based on C-mode commands, and the other on FINS (CV-mode) com-
