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

Benefits
Compared with the other SIMATIC S7-1500 CPUs, the compact CPUs offer added value in a
small space:
• The CPU with 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
