Product Introduction
When you’re building out an AC 800M rack, the baseplate is the unsung hero that actually makes the expansion modules work. The ABB TP867 is a dedicated termination panel designed to serve as the mechanical and electrical foundation for high-end ABB communication modules. It provides the crucial CEX-bus backplane connectivity that allows modules like the CI867 Modbus TCP interface to talk to the PM867 CPU without requiring you to wire a separate communication cable for every single card.
Bottom line — this passive baseplate is what keeps your cabinet build clean and reliable. By routing the 24 VDC supply and CEX-bus signals internally, the ABB TP867 eliminates a massive amount of point-to-point wiring, reducing the chance of human error during commissioning. It’s a 60 mm wide, DIN-rail mounted piece of hardware, but it is absolutely mandatory if you want to plug a CI867 into your system. (And trust me, trying to rig up a CI867 without the proper TP867 baseplate is a great way to fry a $2,000 comms module).
QA/QC Transparency SOP
- Intake & Origin Verification: We verify the ABB TP867 against OEM lot records (3BSE043664R1) and inspect the CEX-bus connectors for bent pins or thermal damage. Since it’s a passive plate, we focus heavily on mechanical integrity.
- Live Functional Testing: The TP867 is seated in a dedicated AC 800M test rack with a PM867 CPU and a CI867 module. We verify that the CEX-bus handshake completes and that the 24 VDC routing passes through to the top module correctly.
- Electrical Parameter Tests: Using a calibrated multimeter, we perform a continuity check on all backplane pins to rule out internal trace breaks. Insulation resistance is verified to ensure no shorts exist between the 24 VDC and signal lines.
- Firmware/Config Verification: N/A. The ABB is a passive hardware component with no firmware. We do, however, verify the physical revision matches the requested part number.
- Final QC & Anti-Static Packaging: A QA signature is applied after passing all mechanical and electrical tests. The baseplate is sealed in an anti-static bag and packed securely to protect the delicate CEX-bus connector during transit.
Field Engineer Gotchas
- Confusing Baseplates with Active Modules: The is a passive baseplate. It does not process Modbus TCP or any other protocol. Blunt warning: If you order a expecting it to give you Ethernet ports, you’re going to have a bad day. You still need the CI867 module to plug into it.
- CEX-Bus Pin Damage: The connector on the back of the is highly sensitive. If you force the module on at an angle, you will bend the CEX-bus pins. Always ensure the DIN-rail is perfectly aligned before sliding the module down.
- Wiring/Terminal Incompatibility: The routes 24 VDC from the PM867 CPU. Do not inject external 24 VDC into the terminals unless explicitly specified in the AC 800M hardware manual. Backfeeding can destroy the CPU’s internal power supply.
- DIN-Rail Grounding: The relies on the DIN-rail for chassis grounding. If you mount it on a plastic DIN-rail or a rusty metal one, you will introduce noise into the CEX-bus. Always use the standard ABB DIN-rail and ensure the grounding clip is making solid metal-to-metal contact.

Application Scenarios
- Oil & Gas DCS Networks: High-availability controllers require stable CEX-bus communications for CI-series modules. The ensures that Modbus TCP or PROFIBUS expansion cards maintain deterministic communication with the PM867 CPU in harsh electrical environments.
- Pulp & Paper Machine Controls: Clean, standardized DIN-rail builds are critical when managing multiple machines. The simplifies cabinet layouts by eliminating external jumper wires between the CPU and communication modules.
- Power Generation Turbine Controls: Stable mounting and precise 24 VDC routing are mandatory for balance-of-plant controls. The provides the reliable mechanical fitment needed to prevent vibration-related intermittents in turbine halls.
FAQ
No. The is specifically designed for the high-end PM867/PM867A CPUs. The PM866 uses a different baseplate (typically the TP830 series). Always verify CPU compatibility in the AC 800M hardware manual before ordering.
No. The routes the nominal 24 VDC supply directly from the CPU via the CEX-bus. No additional external power source is required for the baseplate itself.
The is compatible with the , CI868, CI871, CI873, and CI874 modules. If you are using a different CI-series module, check the ABB documentation to ensure you have the correct baseplate.
Is this a drop-in replacement for older baseplates?
Yes, as long as you are replacing a (3BSE043664R1). It is a direct mechanical and electrical replacement. Just ensure your DIN-rail spacing is correct (60 mm width).
Probably not. Baseplates rarely fail. Check the LEDs first, verify the Ethernet cabling, and ensure the CPU is configured correctly in Control Builder. Only suspect the if you have physical damage to the CEX-bus connector.
Do you test the CEX-bus continuity before shipping?
Yes. Every undergoes a continuity test on all backplane pins and a live functional test with a and module. You will receive a QA report with your shipment confirming it passed.
