Product Overview 1

1-2 CM35 Counter Module
(4) J31069-D0416-U001-A5-7618
1.1 Overview
The CM35 is a multi--channel counter module which can be used to imple-
ment various tasks in the following operating modes.
SPulse counter
SPeriod duration measurement
STimer
SPositioning With 4 axes
The selected operating mode applies to all channels of the CM35. The func-
tion parameters can be set separately for each channel.
The counter module has eight floating digital inputs and outputs which are
used for the inputs and outputs of the counting channels. The signals are led
out via two sub D sockets on the front.
When not used for the operating mode, the outputs can be used as desired by
the user program as process I/O.
The module can be used for position encoding and positioning as well as in
the following systems.
-- Proportioning systems
-- Filling systems
-- Packaging systems
-- Sorting systems
-- Systems with defined time intervals
The counter module can be used centrally on the SIMATIC S7--300 and as
distributed I/O on the modular ET 200M I/O device on the SIMATIC S7 and
SIMATIC S5. The conventional configuration procedures of STEP 7 or
COM PROFIBUS (for SIMATIC S5) are used for the configuration.

The CM35 is equipped with the following front plug connectors for connec-
tion of the process I/O.
S25--pin sub D socket for connection of the input signals (digital inputs)
The inputs are individually isolated from one another and can be used
with a 5 V or 24 V signal level.
S15--pin sub D socket with digital outputs and the connection for the exter-
nal supply voltage for the digital outputs
The outputs are isolated against the module logic, but are not isolated
among one another. They are powered with a supply voltage of 24 V DC.
The red SF LED on the front indicates that the module is not ready for opera-
tion. This LED goes off when a valid parameterization was transferred to the
module after a warm restart or hot restart and the BASP/OD signal is no lon-
ger active.
The CM35 does not support diagnostic alarms and the STEP 7 diagnostic
information.

1.4 Software
The firmware of the module offers four different operating modes.
SPulse counter
Continuous counting with maximum counting frequencies of 10 kHz
SPeriod duration measurement
Measurement of period durations between 1 msec and 2.6 sec with a reso-
lution of 1% on all 8 channels (reference frequencies: 100 kHz, 50 kHz,
25 kHz)
STimer
8 separate switch--on times from 10 msec to 278 min
SPositioning
4 axes with a max. of 231 increments up to a top frequency of
2kHz
The desired operating mode is selected via the configuration user interface.
Note
The following applies when the CM35 is used to acquire frequencies.
SFor lower frequencies: ²period duration measurement²operating mode is
recommended (the period duration can be converted to a frequency).
SFor higher frequencies: ²pulse counting²operating mode is recom-
mended.
Depending on use on the SIMATIC S7 or decentralized on the SIMATIC S5,
configuration of the module is performed with the ²SIMATIC Manager²or
with ²COM PROFIBUS.²
