The firmware of the module offers four different operating modes.
Pulse counter
S
Continuous counting with maximum counting frequencies of 10 kHz
Period duration measurement
S
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)
Timer
S
8 separate switch- - on times from 10 msec to 278 min
Positioning
S
4 axes with a max. of 2
2 kHz
The desired operating mode is selected via the configuration user interface.
Note
The following applies when the CM35 is used to acquire frequencies.
For lower frequencies: ²period duration measurement² operating mode is
S
recommended (the period duration can be converted to a frequency).
For higher frequencies: ²pulse counting² operating mode is recom-
S
mended.
Depending on use on the SIMATIC S7 or decentralized on the SIMATIC S5,
configuration of the module is performed with the ²SIMATIC Manager² or
with ²COM PROFIBUS.²
