High-speed counters
Properties
The technology functions of the compact CPU have the following technical properties:
● 32 high-speed digital inputs (up to 100 kHz), isolated
– 6 high-speed counters (High Speed Counter/HSC), which can all be used as A/B/N
● Interfaces
– 24 V encoder signals of sourcing or push-pull encoders and sensors
– 24 V encoder supply output, short-circuit-proof
– Up to 2 additional digital inputs per high-speed counter for possible HSC DI functions
(Sync, Capture, Gate)
– 1 digital output per high-speed counter for fast reaction to the count
● Counting range: 32 bits
● Diagnostics and hardware interrupts can be configured
● Supported encoder/signal types
– 24 V incremental encoder
(with 2 tracks A and B, phase-shifted by 90°, up to 6 incremental encoders also with
zero track N)
– 24 V pulse encoder with direction signal
– 24 V pulse encoder without direction signal
– 24 V pulse encoder each for forward pulse & reverse pulse
The high-speed counters support reconfiguration in RUN. You can find additional information
in section Parameter data records of the high-speed counters (Page 162).
