Product Introduction
The TP867 is not a standalone communication module. It is the base plate that holds the CI867 or CI867K01 Modbus TCP interface in an ABB AC 800M rack. The actual Ethernet ports, protocol stack, and network behavior come from the CI867/CI867K01 module installed on it. If you are replacing a failed communication channel, you usually need both a working base plate and a compatible CI867/ module.
This matters during maintenance because a damaged base plate can cause poor backplane contact, intermittent communication loss, or module detection errors. The TP867’s 60 mm width matches the family footprint, and the assembly supports hot-swap when used with . For AC 800M systems that rely on Modbus TCP for third-party PLC integration, field instruments, or remote I/O, keeping a verified TP867 + set in spares can shorten outage time.
QA/QC Transparency SOP
- Intake & Origin Verification: Confirm model TP867 and order code 3BSE03664R1/3BSE043664R1 as marked. Photograph labels, revision codes, and backplane contacts.
- Mechanical Inspection: Check for bent pins, cracked housing, damaged retaining clips, or corrosion on the backplane interface. Verify that the / module seats firmly without excessive force.
- Backplane Continuity Check: Test continuity between base plate contacts and module interface points. Confirm there are no open circuits or shorted pins.
- Functional Verification: Install a known-good module. Power the rack and verify that the controller detects the module, Ethernet link LEDs behave normally, and Modbus TCP communication is stable.
- Final QC & Packaging: Record test results, module compatibility, and condition grade. Package with anti-static protection and clear labeling to prevent base plate/module mismatch.
Field Engineer Gotchas
TP867 is not a module. Ordering only the base plate will not restore Modbus TCP communication if the / module itself is faulty. Always confirm whether the failure is in the base plate, the module, the Ethernet cable, or the controller configuration.
vs . The K01 variant explicitly supports hot-swap. If your system requires online replacement, verify that the installed module is and that the base plate revision is compatible.
Backplane seating errors. A loosely seated base plate or module can cause intermittent faults that look like network issues. After installation, verify mechanical retention and recheck Ethernet link status.
Revision mismatches. ABB base plates and communication modules may have hardware revisions. Do not assume that any 60 mm base plate is interchangeable. Match the order code and confirm compatibility with the AC 800M rack.
Ethernet channel differences. Channel 1 supports 10/100 Mbit/s, while Channel 2 is limited to 10 Mbit/s on . If a network switch port is forced to 100 Mbit/s on Channel 2, the link may fail.

Application Scenarios
AC 800M Modbus TCP integration. The + assembly is commonly used when an AC 800M controller must communicate with third-party PLCs, RTUs, or Modbus TCP devices.
Redundant or multi-network architectures. In systems with separate control and monitoring networks, the dual-channel interface can help isolate traffic, provided switch settings match each channel’s speed capability.
Spare-part provisioning for legacy racks. For plants maintaining older AC 800M installations, a tested base plate reduces the risk of extended downtime when a backplane fault is suspected.
Anonymized field note: A process unit reported intermittent Modbus TCP drops on an AC 800M rack. The module showed no physical damage, but reseating the module did not clear the fault. Inspection revealed corrosion on the base plate contacts. Replacing the base plate and cleaning the rack slot restored stable communication.
FAQ
Is a communication module?
No. It is the base plate. The Modbus TCP function comes from the or module mounted on it.
Can I use with modules other than ?
No. It is intended for the / Modbus TCP interface family. Do not install unrelated AC 800M modules on it.
Does it support hot-swap?
Hot-swap is supported when used with . Confirm the exact module type before relying on online replacement.
What Ethernet speeds are supported?
Channel 1 supports 10/100 Mbit/s; Channel 2 supports 10 Mbit/s on .
Is 3BSE043664R1 still available?
It is commonly found through surplus and industrial automation suppliers, but stock condition varies. Request revision details and test records before purchase.
Should I replace the base plate every time a fails?
Not necessarily. Replace the only if there is physical damage, contact corrosion, or persistent backplane communication errors.
