Description
Product Introduction
The Horner HE693PBM101 is a specialized Profibus DP Master communication module designed to install directly into the rack backplane of a GE Fanuc Series 90-30 PLC. Developed by Horner APG as a third-party enhancement for GE Fanuc systems, this module enables Series 90-30 CPUs to orchestrate high-speed data exchanges across vast Profibus DP field networks.
Instead of running hundreds of discrete wires from motor drives, remote I/O blocks, and valve manifolds back to the main cabinet, the HE693PBM101 aggregates all remote node data onto a single shielded twisted-pair cable. It handles heavy cyclic network scanning independently, relieving the main CPU from communication overhead and preserving fast logic scan times.

Application Scenarios & The “Trench” Experience
It’s 10:30 PM on a Tuesday at a bottling facility. A major packaging line halts because the main Series 90-30 PLC loses contact with five remote motor drives and three valve blocks simultaneously. The CPU isn’t faulted, but the network master card’s “BUS FAULT” LED is glowing solid red due to an internal RS-485 transceiver failure. Without communication to the field drives, the entire line sits dead, racking up thousands of dollars an hour in lost throughput.
Primary Industrial Applications
- Automotive Stamping & Assembly – Welding & Valve Island Control – Coordinates rapid I/O handshakes with robotic end-effectors over Profibus.
- Food & Beverage Packaging – High-Speed Conveyor Lines – Interfaces variable frequency drives (VFDs) and photo-eye arrays with a central Series 90-30 CPU.
- Water & Wastewater Treatment – Distributed Pump Stations – Gathers flow and pressure telemetries across spread-out pump house nodes.
- Pharmaceutical Manufacturing – Cleanroom HVAC & Batching – Reads distributed temperature/humidity sensors while maintaining strict loop isolation.
Field Case Study
A chemical processing plant in Indiana experienced a total communication blackout on its reactor batching rack when the legacy HE693PBM101 card suffered a electrical surge. The OEM quoted a full PLC migration to a modern PAC controller platform, requiring 3 weeks of downtime and panel rewiring. Instead, the plant engineer ordered a pre-tested surplus HE693PBM101. The team plugged in the replacement card, downloaded the original network configuration file via the serial config port, and restored full plant production in under two hours.

Transparency SOP: Quality Assurance & Testing
We test third-party GE Fanuc modules on live Series 90-30 racks. Here is our QA procedure:
- Physical Component Inspection: Checking card-edge connectors, front panel 9-pin Sub-D ports, and onboard components for heat discoloration, cracked solder joints, or corrosion.
- Backplane Boot Verification: Inserting the card into a live Series 90-30 rack (e.g., IC693CHS391) to confirm CPU recognition, internal 5V regulator health, and initial LED self-tests.
- Profibus Network Traffic Loop Test: Connecting the module to a live Profibus DP network loop with active slave nodes (VFDs/I/O blocks) at 12 Mbps to verify zero packet corruption or dropping.
- Config Port Auditing: Establishing a serial connection with Horner configuration software (e.g., Cscape / Profibus Configurator) to verify configuration upload/download functionality.
- Static Packaging & Shipping: Clearing diagnostic fault tables, wrapping the card in an anti-static ESD shielding sleeve, and packing it inside a custom foam-lined box.
The Veteran’s Tech Trap Guide (Crucial Value-Add)
⚠️ Trap 1: Check Your Bus Termination Resistors First!
Before replacing a suspected dead HE693PBM101 module, inspect the physical Profibus DB9 connectors at both ends of the cable segment. The switches on the DB9 plugs MUST be set to “ON” at the physical first and last devices on the line, and “OFF” on all intermediate nodes. A flipped termination switch causes signal reflections that mimic a dead master card.
❗ Trap 2: Backup the GSD Files and Network Configuration.
The stores an internal Profibus network map (GSD files, slave node addresses, I/O memory allocation). Replacing the hardware alone will not bring the network up—you must re-download the network .cfg file to the new module using the Horner Profibus Configuration software via the front port.
⚠️ Trap 3: Respect Backplane Current Limits.
The draws 400 mA directly from the Series 90-30 backplane 5 VDC rail. If you are adding this module to a dense rack containing multiple high-draw specialty cards, verify that your rack power supply (e.g., IC693PWR321) has enough overhead, or the power supply will enter over-current shutdown.
❗ Trap 4: Never Insert or Remove Cards Under Power.
The GE Fanuc Series 90-30 rack backplane is NOT hot-swappable. Pulling or inserting the while the rack power supply is energized can cause an electrical arc across the gold edge pins, damaging both the card and the backplane. Always turn off rack power before swapping cards.
Frequently Asked Questions (FAQ for Conversion)
Q: Is the Horner module hot-swappable?
A: No. The GE Fanuc Series 90-30 architecture does not support hot-swapping option cards. Always de-energize the PLC rack power supply before removing or installing the card to prevent backplane or module damage.
Q: Can I use this module to connect a Series 90-30 PLC to a Profibus network as a Slave?
A: No. The is strictly a Profibus DP Master controller. If you need the Series 90-30 PLC to act as a slave node on another master’s network, you need the Horner HE693PBS101 (Profibus Slave) module.
Q: What configuration software is required for the ?
A: Network setup requires Horner’s dedicated Profibus Configuration Software (or Cscape depending on firmware version) along with the GSD files for all connected field slave devices.
Q: Why buy new surplus or refurbished Horner modules over a complete system upgrade?
A: Replacing an entire PLC platform involves drawing new wiring schematics, re-writing PLC logic, and scheduling long plant outages. A pre-tested surplus card provides a drop-in repair that gets your facility running immediately at a fraction of the cost.
Q: What warranty comes with this module?
A: Every Horner card shipped includes a full 12-month functional replacement warranty. If the card experiences hardware or communication failures during normal operation within one year, we replace it immediately.
