1-1 CPM2C Features and Functions
1-1-1 CPM2C Features
The two communications ports (peripheral and
RS-232C) can be used simultaneously.
The peripheral port supports Programming Devices,
Host Link, and no-protocol communications.
The RS-232C port supports Host Link, no-protocol
(serial), 1:1 Link, and 1:1 NT Link communications.

Devices
The CPM2C PCs incorporate a variety of features in a compact Unit, including
synchronized pulse control, interrupt inputs, pulse outputs, and a clock function.
The CPM2C CPU Unit is a stand-alone Unit that can handle a broad range of
machine control applications and it is small enough to be incorporated as the
control unit in almost any free-standing machine.
The full complement of communications functions provide communications with
personal computers, other OMRON PCs, and OMRON Programmable Termi-
nals. These communications capabilities allow the user to design a low-cost dis-
tributed production system.
The CPM2C PCs are one-piece PCs with 10 or 20 I/O points in I/O terminals or a
connector port. in the built-in connectors. There are 3 types of outputs available
(relay outputs, sinking transistor outputs, and sourcing transistor outputs). All
CPM2C PCs require a 24-VDC power supply.
Up to 5 Expansion I/O Units can be connected to the CPU Unit to increase the
PC's I/O capacity to a maximum of 140 I/O points. There are 2 types of Expan-
sion I/O Units available: one with 24 I/O points and the other with 10 I/O points.
The maximum I/O capacity of 140 I/O points is achieved by connecting five
24-point Expansion I/O Units to a CPU Unit with 20 built-in I/O points.
The same Programming Devices, such as Programming Consoles and Support
Software, can be used for the C200H, C200HS, C200HX/HG/HE, CQM1,
CPM1, CPM1A, CPM2A, and SRM1(-V2) PCs, so existing ladder program re-
sources can be used effectively.
CPU Units with 10 I/O points (relay or transistor
outputs) or 20 I/O points (transistor outputs only)
are available. Expansion I/O Units can be con-
nected to increase capacity to 140 I/O points.
