Compact PLC Series CPM2C
System Configuration
Configuration
The individual Units of the CPM2C system are plugged in to one
another and secured using 2 locking sliders. The system must be
mounted on DIN rail.
Communication interfaces
The CPM2C has one peripheral and one RS−232C interface on a
miniature peripheral socket. They can both be accessed via the
CPM2C−CN111 adapter cable.
For other adapter cables, see page 61.
Both ports can be used simultaneously.

Expansion of the CPM2C
Up to five Expansion Units can be connected to CPM2C CPU Units,
and up to three Expansion Units to CPM2C−S100C/S110C Units. Only
a total of four of the CPM2C−MAD11 and CPM2C−TS_ Expansion Units
can be connected.
Interrupt input
Two or four of the normal transistor inputs can also be configured as
interrupt inputs. Various interrupt modes are available.
Pulse outputs
Only CPM2C CPU Units with transistor outputs provide a pulse output
function. These pulse outputs are to be subtracted from the number of
available standard outputs.

High–speed counter inputs
If the high−speed counter function is required, three of the normal
transistor inputs are occupied. The high−speed counter input can be
used to connect an encoder with phases A, B and Z, for example.
– Differential phase mode
The maximum input frequency is 5 kHz.
Each upward and each downward edge is counted, i.e. at 5 kHz,
20,000 pulses per second are counted.
The Z phase can be used as a reset signal.
– Pulse/direction mode
The maximum counting frequency is 20 kHz.
