Key Features
- 1-channel counter module: TM Count 1x24V with 1 channel for 24 V incremental encoder or pulse encoder.
- I/O capacity: Provides 3 DI and 2 DQ.
- Selection and installation: Suitable for BU type A0 and supports automatic encoding with mechanical coding element type B.
- Engineering and integration: Configurable in STEP 7 TIA Portal from version STEP 7 V15 SP1 or higher, and in STEP 7 from V5.6 and higher.
- Diagnostics and functions: Supports diagnostic alarm, hardware interrupt, monitoring of the supply voltage, wire break, short-circuit, and A/B transition error at incremental encoder.
Applications
- 24 V encoder counting: Counting and position detection for a 24 V incremental encoder or pulse encoder.
- Digital signal handling: Use of 3 DI and 2 DQ for gate start/stop, capture, synchronization, probe, and comparison-value switching.
