GE Fanuc IC695HSC304-DA – 4-Channel High Speed Counter Module | PACSystems RX3i
Engineering Background
The IC695HSC304-DA is a dedicated high-speed counter (HSC) module designed for GE Fanuc’s PACSystems RX3i platform. It addresses the need for precise, high-frequency pulse counting in motion control, packaging, and process automation applications where the standard CPU scan cycle is too slow to capture fast encoder or sensor signals reliably.
Product Positioning
Targeted at procurement engineers and system integrators requiring deterministic pulse capture up to 1 MHz per channel, this module offloads counting tasks from the RX3i CPU, ensuring zero missed counts even under heavy PLC program loads. The “-DA” suffix denotes the differential input variant, offering superior noise immunity for industrial environments.

Proven Application Environments
- Packaging Machinery: Accurate web speed and cut-length measurement using quadrature encoders on servo axes.
- Conveyor & Material Handling: Position tracking and part counting on high-speed lines without CPU scan-rate limitations.
- CNC & Motion Control: Spindle speed feedback and axis position verification in multi-axis RX3i-based motion systems.
- Flow Measurement: Turbine and gear-type flow meter pulse accumulation for custody-transfer accuracy.
- Press & Stamping: Stroke counting and cam-position monitoring with Z-index reset on each revolution.
Engineering Advantages
- Scan-Independent Counting: Hardware counters operate asynchronously from the PLC scan, eliminating missed pulses at high frequencies.
- Differential Inputs (DA Variant): RS-422 differential signaling rejects common-mode noise, critical in electrically noisy industrial cabinets.
- 32-Bit Counter Depth: Supports up to 4,294,967,295 counts before rollover — suitable for long-run production without reset.
- Flexible Encoder Modes: Single configurable module supports quadrature ×1/×2/×4, pulse/direction, and up/down modes per channel.
- Compare Outputs: On-board preset compare outputs enable direct actuator triggering without CPU ladder logic latency.
- Hot-Swap Capable: RX3i backplane supports module replacement under power (with appropriate system configuration).
System Architecture & Signal Flow
The IC695HSC304-DA occupies a single slot on the RX3i Universal Backplane. Encoder or pulse-train signals connect via the module’s front-panel terminal block or connector. Each channel’s hardware counter increments/decrements independently of the CPU scan. Count values, status bits, and compare outputs are mapped to the RX3i I/O reference table and are accessible from any PACSystems CPU (IC695CPU310, IC695CPU320, IC695CPE305, etc.) via standard %I/%Q/%R/%AI/%AQ references. Configuration is performed in Proficy Machine Edition (PME) using the HSC module’s hardware configuration dialog.

Technical FAQ
- Q: Is the IC695HSC304-DA compatible with the RX3i CPE330 CPU?
- A: Yes. The module is compatible with all RX3i Universal Backplane CPUs including CPE305, CPE310, CPE330, and CPE400 series, subject to PME firmware version support.
- Q: What is the difference between IC695HSC304 and IC695HSC304-DA?
- A: The “-DA” suffix designates differential analog inputs (RS-422), providing better noise immunity versus the single-ended TTL variant. Confirm your encoder output type before ordering.
- Q: Can I use this module with a Series 90-30 backplane?
- A: No. The IC695HSC304-DA is designed exclusively for the RX3i (IC695 series) Universal Backplane and is not backward-compatible with Series 90-30 (IC693) hardware.
- Q: How do I configure the module in Proficy Machine Edition?
- A: In PME, navigate to the hardware configuration tree, add the IC695HSC304-DA to the target slot, and configure each channel’s mode (quadrature/pulse-direction/up-down), count direction, preset values, and compare output assignments in the module’s parameter dialog.
- Q: What encoder voltage levels are supported?
- A: The differential inputs are compatible with RS-422 signal levels (±2 V differential). Ensure your encoder driver meets RS-422 specifications for reliable operation at 1 MHz.
