Introduction
4-1-1 Overview
The CPM1/CPM1A can execute a variety of communications through its periph-
eral port via an RS-232C Adapter or an RS-422 Adapter.
Host Link Communications
The CPM1/CPM1A PCs are compatible with the Host Link System, which allows
up to 32 PCs to be controlled from a host computer. An RS-232C Adapter is used
for 1:1 communications and an RS-422 Adapter and B500-AL004 Link Adapter
are used for 1:N communications.
A CPM1/CPM1A equipped with an RS-232C Adapter can also communicate
with a OMRON Programmable Terminal using host link commands.
Refer to
4-2-1 CPM1/CPM1A Host Link Communications
in this manual and
1-2-2 Host Link Communications
in the
CPM1 Operation Manual
or
1-2-2 Host
Link Communications
in the
CPM1A Operation Manual
for more details.
One-to-one PC Link
A data link can be created with a data area in another CPM1, CPM1A, CPM2A,
CPM2C, CQM1, C200HX/HG/HE, or C200HS PC. An RS-232C Adapter is used
to make the 1:1 connection.
Refer to
4-2-3 CPM1/CPM1A 1:1 PC Link Communications
in this manual and
1-2-3 One-to-one PC Communications Links
in the
CPM1 Operation Manual
or
1-2-3 One-to-one PC Communications Links
in the
CPM1A Operation Manual
for more details.
One-to-one NT Link
Using the 1:1 NT Link, the CPM1/CPM1A PC can connected to the OMRON
Programmable Terminal (NT Link Interface) through an RS-232C Adapter.
Refer to
4-2-2 CPM1/CPM1A 1:1 NT Link Communications
in this manual and
1-2-4 One-to-one NT Link Communications
in the
CPM1 Operation Manual
or
NT Link Communications
in the
CPM1A Operation Manual
for more details.
The following types of communications can be executed through the ports of the
CPM2A/CPM2C.
•
Host Link communications with a host computer
•
RS-232C communications with a computer or other device
•
One-to-one PC Link communications with another PC
•
One-to-one NT Link communications with OMRON Programmable Terminals
This section explains the required PC Setup and methods for using these types
of communications.
SRM1(-V2) Communications
The following types of communications can be executed through the ports of the
SRM1(-V2).
•
Host Link communications with a host computer
•
RS-232C communications with a computer or other device
•
One-to-one PC Link communications with another PC
•
One-to-one NT Link communications with OMRON Programmable Terminals
Note
One-to-one NT Link communications are not possible with the SRM1-C01,
which is equipped with only a peripheral port. The SRM1-C01 may be connected
to a PT through an RS-232C Adapter in Host Link mode.
4-1-2 Wiring Ports
Refer to the
CPM1 Operation Manual, CPM1A Operation Manual,
CPM2A Op-
eration Manual,
CPM2C Operation Manual
, or
SRM1 Master Control Units Op-
eration Manual
for information on wiring the communications ports.
