Technology Functions Of The Compact Cpus - Siemens SIMATIC S7-1500/ET 200MP System Manual

System overview
4.8 Technology functions
Benefits
The integrated controller PID Control of the SIMATIC S7-1500 CPUs offer you the following
advantages:
• High-quality end product due to optimum control performance
• High flexibility in the drying oven (see example)
• Time savings thanks to automatic control parameter optimization for optimum control
performance and simple commissioning

Period duration measurement
Velocity measurement
Pulse width modulation (PWM
output)
Pulse Train Output (PTO output)
Frequency output
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
