Function
Value
Description
Six high-speed counters
up to 100 kHz
For pulse and incremental encoders
Frequency measurement
0.04 Hz - 400 kHz
Period duration measurement
2.5 μs
- 25 s
Velocity measurement
Dependent on measurement interval and signal evaluation
Unit can be defined by user
Pulse width modulation (PWM
output)
max. 4 (up to 100
kHz)
Output of a signal with defined period duration and variable
on-load factor at DQ
Pulse Train Output (PTO output)
max. 4 (up to 100
kHz)
Output of position information, e. g. for activation of stepper
motor drives or simulation of an incremental encoder
Frequency output
up to 100 kHz
Precise assignment of a frequency value with high frequen-

Benefits
Compared with the other SIMATIC S7-1500 CPUs, the compact CPUs offer added value in a
small space:
●
They combine CPU with front display and inputs/outputs in one enclosure
●
compact size with high performance
●
important technology functions such as counting, measuring and positioning are
integrated
●
cost effective compared to modular systems with CPU and modules
●
space saving design
●
can be expanded by SIMATIC S7-1500 input and output modules
