6 fast counters (3 with max. 100 kHz; 3 with max. 30 kHz), with parameterizable enable and reset inputs, can be used simultaneously as up and down counters with 2 separate inputs or for connecting incremental encoders
Expansion by additional communication interfaces, e.g. RS485 or RS232
Expansion by analog or digital signals directly on the CPU via signal board (with retention of CPU mounting dimensions)
Expansion by a wide range of analog and digital input and output signals via signal modules
Optional memory expansion (SIMATIC Memory Card)
PID controller with auto-tuning functionality
Integral real-time clock
Interrupt inputs:
For extremely fast response to rising or falling edges of process signals
Removable terminals on all modules
Simulator (optional): For simulating the integrated inputs and for testing the user program
