1-1-1 CPM2B Features
The CPM2B PLCs are compact Board PLCs that can be incorporated easily
into control equipment. The PLCs are equipped with a variety of advanced
features including synchronized pulse control, interrupt inputs, high-speed
counters, pulse outputs, and a clock function.
• The compact Board design is ideal for incorporation into control equip-
ment.
• The CPU Board itself can handle a wide range of machine control appli-
cations, so it is ideal for use as a built-in control unit in control equipment.
• The CPM2B is equipped with a full complement of communications func-
tions to provide communications with personal computers, other OMRON
PLCs, and OMRON Programmable Terminals. These communications
capabilities allow the user to design a low-cost distributed production sys-
tem.
Basic Functions
CPU Board I/O The CPM2B CPU Board itself is equipped with 32 or 40 I/O points in I/O termi-
nals or I/O connectors. There are 2 types of outputs available (relay outputs
and sinking transistor outputs). The power supply for the CPM2B CPU Board
is either 12 V DC or 24 V DC only.
Expansion I/O Boards Up to two 64-point Expansion I/O Boards can be connected to the CPU Board
to increase the PLC’s I/O capacity to a maximum of 168 I/O points. There are
also four types of 32-point Expansion I/O Boards available: two with relay out-
puts and the other with sinking transistor outputs. Up to three 32-point Expan-
sion I/O Boards can be connected to the CPU Board.
Share Programming
Devices
The CX-Programmer (Ver.1.2 or later) or Programming Console can be used
for programming and monitoring the CPM2B. Programming can also be per-
formed from the SYSMAC Support Software (SSS).
The CPU Board has 32 or 40 I/O points and Expan
sion I/O Boards can be added to provide a total I/O
capacity of up to 168 I/O points.
Peripheral Port
Programming Devices are compatible with other
models of OMRON PLCs. This port can also be
used for Host Link or no-protocol communications.
RS-232C Port
This port can be used for a Host Link,
no-protocol, 1:1 PLC Link, or 1:1 NT
Link communications.
