Overview
Technical properties
- Counter module for ET 200SP
- Interfaces:
- 24 V encoder signals A, B and N from P, M or push-pull-switching encoders and sensors
- 24 V encoder supply output, short-circuit proof
- 3 digital inputs for controlling the count operation, for saving or for setting the count value
- 2 digital outputs for fast reactions regardless of the counter status or measured value
- Counting frequency 200 kHz (800 kHz with quadruple evaluation)
- Counting range: +/- 31 bits
- Measurement function
- Parameterizable hardware interrupts
- Parameterizable input filters for suppressing interferences at sensor and digital inputs
Supported types of encoders/signals
- 24 V incremental encoder with and without signal N
- 24 V pulse encoder with direction signal
- 24 V pulse encoder without direction signal
- 24 V pulse encoder for pulse up and down respectively
Supported system functions
- Isochronous mode
- Firmware update
- Identification data I&M
Application
In particular, the TM Count 1x24V counter module detects high-speed signals with high frequencies and returns the counter reading and the current speed to the control. The counter control ensures a precise counter result and rapid response in the system via integrated digital input and output signals. Comprehensive parameterization options provide optimum adaptation to the task at hand and reduce control load.
In particular, the TM Count 1x24V counter module is suitable for position detection for HTL incremental encoders for use with Motion Control technology objects of the SIMATIC S7-1500 Advanced Controller.
Design
Suitable BaseUnits
The standard BaseUnits Type A0 of ET 200SP are available for connection. The individual signals of the counter module are connected to the appropriate terminals.
A light BaseUnit opens a new load group. The supply voltage must be fed in via this BaseUnit. The first BaseUnit next to the interface module must always be a light BaseUnit.
A dark BaseUnit forwards the supply voltage of the adjacent light BaseUnit on the left via self-assembling voltage buses. A new infeed is therefore only required on the next light BaseUnit to the right.
All variants that correspond to BaseUnit type A0 can be used as BaseUnits.
System-integrated shield connection
For the space-saving and EMC-optimized connection of cable shields, a shield connection is available that is quick and easy to mount. This consists of one shield connection element that can be plugged onto the BaseUnit and one shield terminal for each module. The low-impedance connection to functional ground (DIN rail) is carried out by the user and requires no additional wiring.
