The HE693PBM101 functions as a PROFIBUS DP network master for the GE Fanuc Series 90-30 PLC platform. It supports up to 64 slave devices and is intended exclusively for PROFIBUS DP communication; it does not support PROFIBUS FMS or PA.
Product Introduction
The GE Fanuc HE693PBM101 is a PROFIBUS DP Master communication module developed by Horner APG for the Series 90-30 PLC platform. It enables the PLC to exchange cyclic data with remote I/O, drives, valves, transmitters, and other PROFIBUS DP slave devices through a high-speed industrial network.
The module plugs into a local Series 90-30 rack slot and provides a dedicated PROFIBUS DP interface together with an RS-232 service port for configuration and diagnostics. It remains a common replacement part in existing legacy automation systems where PROFIBUS infrastructure is still deployed.

Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance | Quick Check Method | Recommendation |
|---|---|---|---|---|
| PROFIBUS LED OFF | No backplane power | ✅ High | Verify 5 VDC rack supply | Check PLC power supply before replacing module |
| PROFIBUS network offline | Cable or termination fault | ✅ High | Measure bus termination and inspect connectors | Verify both network terminators |
| Slave devices unavailable | Incorrect GSD configuration | ✅ High | Compare hardware configuration with engineering software | Reload correct GSD files |
| Module remains in STOP | CPU firmware incompatible | ✅ High | Verify CPU350+ with Firmware V8.0 or later | Upgrade CPU firmware if required |
| Communication intermittent | Duplicate PROFIBUS address | ✅ Medium | Scan network addresses | Assign unique station addresses |
| RS-232 service unavailable | Configuration software mismatch | ✅ Medium | Verify VersaPro or CIMPLICITY version | Use supported software release |
| PLC fault after replacement | Wrong module configuration | ✅ High | Compare hardware configuration with original system | Download original configuration before commissioning |
Field Note: The HE693PBM101 rarely fails electrically. Most communication issues are caused by incorrect GSD files, duplicate node addresses, damaged PROFIBUS cabling, or missing bus termination. Before replacing the module, inspect the network with a PROFIBUS analyzer and verify the engineering configuration.
Frequently Asked Questions (FAQ)
Q1. What does the HE693PBM101 do?
It operates as a PROFIBUS DP Master, allowing a Series 90-30 PLC to communicate with remote I/O stations, variable-frequency drives, transmitters, valve controllers, and other PROFIBUS DP slave devices. It supports up to 64 slaves.
Q2. Does it support PROFIBUS PA or FMS?
No. The HE693PBM101 supports PROFIBUS DP only. It does not provide PROFIBUS PA or PROFIBUS FMS functionality.
Q3. Which PLC CPUs are compatible?
The module requires a Series 90-30 CPU350 or higher with firmware version 8.0 or newer. Earlier CPUs and firmware revisions are not supported.
Q4. Can I hot-swap this module?
No. The is not designed for hot swapping. Remove rack power and follow lockout/tagout procedures before installing or removing the module.
Q5. Why can’t the module communicate with all slaves after replacement?
The most common causes are:
- Incorrect GSD files
- Duplicate station addresses
- Incorrect baud rate
- Missing or incorrect PROFIBUS termination
- Hardware configuration not downloaded to the PLC
These issues are more common than hardware failure.
Q6. Is the still manufactured?
No. The is a legacy product for the Series 90-30 platform. Most available units today are supplied as New Surplus or professionally refurbished inventory.
Q7. What tests should a supplier perform before shipment?
A qualified supplier should perform:
- Visual inspection for physical damage
- Backplane power verification
- PROFIBUS communication test
- RS-232 diagnostic port verification
- Functional testing in a Series 90-30 PLC rack
- Anti-static packaging with serialized QC documentation
These checks help confirm that the module is ready for installation in an existing PROFIBUS DP control system.
