Description
The HE700GEN200C (commonly cataloged as part of the HE700GEN200 series) is a specialized Dual-Channel Genius (uGENI) VME Interface Module manufactured by Horner APG for integration within GE Fanuc automation architectures. Designed to bridge VME-based control systems with Genius I/O networks, this module acts as a high-performance communications controller capable of replacing or operating alongside standard Genius Bus Controllers (GBC).

Operating Guidelines and Usage Methods
Proper integration and handling of the VME interface module require strict adherence to electronic safety and industrial networking standards.
- ESD Precautions: Always utilize a certified grounded electrostatic discharge (ESD) wrist strap when handling the module to protect sensitive internal logic circuits and transceivers from static damage.
- Rack Installation: Firmly seat the module into the designated slot within a GE Fanuc VME integrator or Series 90-70 backplane rack, ensuring edge connectors and board guides align correctly before securing retention hardware.
- Network Termination: Ensure the Genius bus is properly terminated at each end using appropriate matching resistors (typically 120 ohms unless specified otherwise by cable impedance ratings) to maintain data integrity across serial loops.
Power-On and Power-Off Sequence
Adhering to correct energization protocols prevents bus communication dropouts and protects rack backplane components.
- Power-On Sequence:
- Verify that the HE700GEN200C module is securely seated in its VME rack slot and field communication cables are firmly terminated to the front-panel screw connectors.
- Switch on the primary rack power supply feeding the system enclosure.
- Monitor system software and module status indicators to verify normal initialization, bus synchronization, and communication polling.
- Power-Off Sequence:
- Take the associated Genius network drops offline or place the PLC CPU into stop/configure mode via programming software if required.
- Power down the main electrical feeds supplying the system rack.
- Allow circuits to fully de-energize before unseating or servicing the module.
Product Instructions
The HE700GEN200C manages asynchronous data exchange between the VME host CPU and remote Genius network devices. Module configuration relies on a combination of onboard hardware DIP switches for hardware address setting and software parameterization via the VME controller environment. Keep cabinet ventilation clean to prevent thermal buildup around high-density bus components.
Frequently Asked Questions (Q&A)
- Q: What system utilizes the HE700GEN200C module?
- A: It is deployed within GE Fanuc Series 90-70 and VME-based industrial control architectures to manage Genius network communications.
- Q: What is the difference between single and dual-channel variants in this family?
- A: The HE700GEN100 is a single-channel interface, whereas the HE700GEN200 / HE700GEN200C is a dual-channel module supporting expanded network routing.
- Q: What should I check if network communication drops on the Genius bus?
- A: Verify physical wiring and termination resistor values at both ends of the serial daisy-chain, check front-panel terminal connections, and confirm proper switch configuration.
