Features:
- Counts one high-speed encoder or pulse channel across a full 32-bit range.
- Provides two threshold comparisons with two protected local outputs.
- Supports event interrupts for zero, limits, overflow and underflow conditions.
This part is the IF 961-CT1 counter interface with submodule identification 03H.
It converts encoder position or pulse accumulation into time-critical M7 application data.
Encoder voltage class, filter, direction, gates and preset values must be taken from the original hardware configuration.

- Packaging axes can monitor incremental encoder travel while using comparisons for registration events.
- Flow or production counters accumulate high-rate pulses beyond the range of standard digital inputs.
- Test rigs use gated periodic counting to measure frequency or movement during a defined sampling window.
- Software and hardware gates determine when counting is enabled.
- Two comparison thresholds can independently control the local output functions.
- Interrupts report zero crossing, comparison events, overflow and underflow to the M7 program.
- Diagnostics cover parameter faults and loss of an expected interrupt condition.
- The 5 V differential interface includes sensor-line monitoring for the encoder tracks.
- Both output channels include electronic protection against a short circuit.
- Differential 5 V signals can be counted at frequencies up to 500 kHz.
- The 24 V input path supports counting rates up to 200 kHz.
- Signed and unsigned 32-bit formats accommodate both directional position and large total values.
