General

The CPM2C Micro PLC is suitable as a controller for simple

stand−alone machines, as well as a simple networked controller. One

innovation is the new synchronisation instruction, which makes it

possible to generate output pulse trains as a function of an input pulse

frequency, e.g. to emulate the synchronisation of 2 axes through a

variable gear ratio. Furthermore, PID control and pulse width

modulation can also be realised easily by preconfigured instructions.

PLC programs from the CPM1/CPM1A and the CPM2A can be used

with the CPM2C. Programming is carried out using the

CX−Programming software.

Features of the CPM2C series:

− Small size, space−saving narrow design

− Removable terminal block or connector

− Real−time clock and backup battery (dependent on type)

− One 20 kHz counter and two 10 kHz pulse outputs

− Peripheral and RS−232C ports in one connector

− Active RS−232C port (RXD/TXD instruction)

− Synchronisation, PID control, and pulse width modulation

instructions

The very small size and DIN rack mounting allow the CPM2C to be

installed in small control cabinets, which can be integrated directly into

machines and therefore save a great deal of space.
