Description
Product Introduction
The Anybus ABX-PDPS-COPS is a industrial-grade protocol coupler manufactured by HMS Networks. It functions as an active data bridge between two distinct industrial fieldbus networks: PROFIBUS DP and CANopen. By operating simultaneously as a PROFIBUS DP Slave and a CANopen Slave, it allows seamless cyclic process data transfer between two independent master controllers—such as a Siemens S7 PLC on PROFIBUS and a Schneider Electric or Beckhoff PLC on CANopen.
Instead of writing custom gateway code or adding complex communication processors to existing PLC racks, the ABX-PDPS-COPS offloads all protocol conversion directly inside its hardware engine. It buffers I/O data into fast internal memory tables, allowing cyclic I/O exchanges up to 244 bytes in each direction without impacting network scan times or controller CPU cycles.

Application Scenarios & The “Trench” Experience
Few things stress a controls team like integrating two plant sections built by different European machine OEMs. Imagine a packaging skid built around a CANopen motion network that needs to tie into the main plant floor managed by a Siemens S7-1500 on PROFIBUS DP. Neither OEM wants to modify their master program or risk voiding machine warranties. Dropping an ABX-PDPS-COPS between the networks acts as a clean neutral buffer zone. Both PLCs see the gateway as a simple, standard I/O device, exchanging data registers cleanly without touching either master’s core execution loop.
- OEM Machine Integration – Bridging CANopen-based servo drive clusters into a main PROFIBUS process automation network.
- Factory Inter-Line Communication – Interfacing legacy German or Italian processing equipment directly to central plant DCS systems.
- Material Handling & Robotics – Passing handshake signals and piece-count data between CANopen skid controllers and PROFIBUS supervisory PLCs.
- Water & Wastewater Treatment – Interfacing CANopen valve manifolds and analytical instrumentation loops directly into PROFIBUS control architectures.
ABX-PDPS-COPS
Transparency SOP: Quality Assurance & Testing
We don’t just ship boxes; we test them on actual Siemens and CANopen test benches. Every surplus or refurbished ABX-PDPS-COPS undergoes a strict 5-stage verification process before shipping:
- Inbound Physical Inspection: Inspection of metal chassis, DIN latch mechanism, terminal connectors, and verification of serial labels and hardware revisions.
- Live Rig Bench Test: Powered up with 24V DC to verify internal power rail stability and monitor boot-up LED diagnostics.
- CANopen Network Handshake: Connected to a CANopen master node. Node ID and baud rate rotary switches verified, along with PDO/SDO register mapping tests.
- PROFIBUS DP Network Validation: Mounted on an active PROFIBUS DP network with a Siemens S7 master controller to confirm automatic baud rate detection up to 12 Mbps and verify cyclic I/O data transfer.
- Memory Clear & Anti-Static Packaging: Unit reset to factory defaults using Anybus Configuration Manager, cleared of former customer configurations, and sealed in ESD-safe packaging.
The Veteran’s Tech Trap Guide (Crucial Value-Add)
⚠️ Set Physical Switches Before Powering Up: The rotary address switches for both PROFIBUS (Node Address) and CANopen (Node ID and Baud Rate) are sampled by the onboard microprocessor only at power-on. If you flip these dials while the 24V supply is attached, the new node settings will not apply until you cycle power.
❗ GSD and EDS File Alignment: You need two separate configuration files for your engineering software: a .GSD file for your PROFIBUS master (e.g., STEP 7 / TIA Portal) and an .EDS file for your CANopen master software. Make sure the total byte sizes configured in both file mappings match perfectly; mismatched I/O byte counts will prevent the gateway from clearing its network fault LEDs.
⚠️ CANopen Bus Termination: Like all CAN networks, the CANopen bus requires a 120-ohm termination resistor across CAN_H and CAN_L at both physical ends of the trunk line. The ABX-PDPS-COPS does not always have an internal termination resistor enabled by default, so verify if your connector hood includes built-in termination.
❗ Endianness & Byte Swapping: PROFIBUS utilizes Big-Endian byte ordering while CANopen frequently uses Little-Endian for 16-bit and 32-bit integer values. Pay close attention to word alignments in your PLC code when transferring multi-byte values like motor speeds or analog values, or use the Anybus Configuration Manager tool to enable automatic byte swapping.
Frequently Asked Questions (FAQ for Conversion)
Q: Can the ABX-PDPS-COPS act as a Master on either PROFIBUS or CANopen?
A: No. The “PDPS-COPS” designation explicitly stands for PROFIBUS Slave (PDPS) and CANopen Slave (COPS). If you need a master on either side, you will require a different X-gateway variant (such as the ABX-PDPM-COPS for PROFIBUS Master).
Q: How do I map data between PROFIBUS and CANopen?
A: Data mapping is handled via the free Anybus Configuration Manager (ACM) software. The gateway acts as a shared memory table where PROFIBUS output bytes automatically map to CANopen input bytes, and vice versa.
Q: Is this gateway hot-swappable?
A: You can disconnect the DB9 fieldbus connectors while the system is live without damaging the hardware. However, removing the plugs will cause a missing node fault on both respective network masters unless those master controllers are programmed to handle disconnected slave nodes gracefully.
Q: Does HMS still manufacture the ABX-PDPS-COPS?
A: HMS has transitioned many legacy X-gateway models to newer hardware revisions or recommended migration paths. Sourcing our tested New Surplus stock guarantees a direct 1:1 replacement drop-in without needing panel modifications or software reconfiguration.
Q: What warranty is included with this unit?
A: All our surplus and refurbished HMS Anybus modules come backed by a full 12-month replacement warranty. If the unit fails during normal operation within 1 year, we will replace it directly from our stock.
