4. Product Introduction
The ABB 07MK92 (GJR5253300R1161) is a serial communication processor module designed for use with ABB Advant Controller 31 (AC31) and Advant OCS automation systems. It provides four serial interfaces — two configurable as RS-232, RS-422, or RS-485 and two fixed RS-232 ports — to link PLCs, field devices, HMIs, and external equipment via user-defined protocols.
This module runs on 24 V DC, includes Flash application memory, and features configurable LED diagnostics. It connects to Advant basic units via network interface elements and is programmed and tested using ABB 907 MK92 software on a PC, offering flexible integration for legacy automation communications.
5. Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No LEDs powered | 24 V DC supply missing or reversed | ✅ High | Measure 24 V at module terminals | Confirm supply polarity and fuses |
| Serial link not active | Wrong port config / baud mismatch | ✅ High | Verify COM3/COM4 settings match remote device | Update protocol and port settings in app |
| Module doesn’t respond to PC tool | Wrong COM port or cable issue | ⚠️ Medium | Test COM3 connectivity and cable continuity | Try known good cable/adapter |
| Unexpected error LED | Flash memory app fault | ⚠️ Medium | Observe LED code pattern | Re-download application via 907 MK92 |
| Erratic data on RS-485 | Termination/shield issues | ⚠️ Medium | Check termination, shield continuity | Add termination resistor, ground shield correctly |
Practical note: Most communication issues trace back to port configuration, termination, or cabling, not hardware failure. Always verify physical connections and protocol settings before module replacement.
6. Frequently Asked Questions (FAQ)
Q1: What system does this module plug into?
A: It integrates with ABB Advant Controller 31 (AC31) and Advant OCS systems as a serial communication processor module.
Q2: How many serial ports does it have?
A: Four total: 2 configurable as RS-232/RS-422/RS-485 (COM3/COM4) and 2 fixed RS-232 (COM5/COM6).
Q3: Do I need special software to program it?
A: Yes — use ABB 907 MK92 PC software to write and test user communication applications stored in Flash EPROM.
Q4: Can this module handle Modbus or Profibus?
A: Protocol support is user-defined in application code and can implement common industrial serial protocols such as Modbus or Profibus if coded accordingly.
Q5: What power does this module require?
A: 24 V DC, typical draw around 2.5 W, with LEDs for supply, run, and error indication.
Q6: Why might this be priced below factory list?
A: This part is legacy/out of active production and offered mainly as New Surplus or tested stock, not from current OEM manufacturing. Verified condition and testing SOP are essential for uptime assurance.
