Product Introduction
ABB YPP110A 3ASD573001A1 is a communication interface module for the ABB AC500 PLC platform. It is used to connect the PLC controller to field devices, drives, and supervisory systems through industrial bus networks.
The module typically supports protocols such as PROFIBUS DP, CANopen, and Modbus RTU/TCP, depending on configuration. It is installed in the AC500 CPU communication slot or left-side expansion slot and works with Automation Builder / Control Builder Plus for configuration.
Because third-party listings sometimes describe YPP110A as a generic I/O board, excitation controller, or drive processor, the exact function should always be confirmed against the module nameplate and host PLC documentation.
Key Technical Specifications
| Parameter | Value |
|---|---|
| Full Order Code | YPP110A / 3ASD573001A1 (nameplate prevails) |

| Mounting | AC500 CPU communication slot / left-side expansion slot |
| Supply Voltage | System-dependent, typically from AC500 backplane |
| Supply Status | Legacy / New Surplus |
Exact port count, protocol set, and firmware should be confirmed from the installed module label and AC500 manual.
Quality Control Process (Dynamic)
- Visual inspection: Check front labels, communication ports, terminal blocks, LEDs, and PCB for oxidation, pin damage, or mechanical stress.
- Firmware verification: Record firmware version, protocol setting, and bus address before dispatch.
- Power-up test: Install the module in a compatible AC500 rack, apply control power, and verify LED status.
- Communication test: Verify bus link recognition and node address behavior using Automation Builder / Control Builder Plus.
- Final packing: Record protocol and firmware details, protect communication ports, and ship in anti-static packaging.
Replacement Pitfall Guide (Dynamic)
❗ Protocol mismatch. YPP110A may support multiple bus protocols, but the active protocol depends on configuration. Replacing it without confirming the original setup may cause communication loss.
❗ Wrong product classification. Some surplus pages describe YPP110A as a generic I/O module, excitation controller, or drive processor. It should be treated as an AC500 communication interface module unless the nameplate proves otherwise.
❗ Firmware/configuration dependency. Bus address, baud rate, termination, and node ID must match the original module. Incorrect settings can trigger bus faults.
❗ Slot dependency. Installing the module in the wrong AC500 slot can prevent recognition or cause I/O mapping errors.
Keep these in mind and you’ll cut 90% of rework time.
Compatibility Matrix & Benchmarks
| Original Model | Replacement / Successor Model | Compatibility Level | Migration Notes |
|---|---|---|---|
| YPP110A (3ASD573001A1) | YPP110A (3ASD573001A1) | Direct | Same order code; confirm firmware, protocol, and slot. |
| YPP110A (3ASD573001A1) | Other AC500 communication modules | Needs Adaptation | Different modules may support different protocols or slot rules. |
| YPP110A (3ASD573001A1) | AC800M / Advant OCS modules | Not Interchangeable | Different ABB platforms and backplane architectures. |
| YPP110A (3ASD573001A1) | Generic RS-485 converters | Not Interchangeable | Not a direct serial-to-bus replacement. |
Benchmark notes:
- AC500 communication interface module supporting PROFIBUS DP, CANopen, and Modbus families.
- Replacement requires matching order code, firmware, protocol configuration, and PLC slot position.
Send a photo of the existing module label, PLC model, slot position, and configured protocol, and we can confirm exact compatibility before dispatch.
