Description
Engineering Value
The ABX-EMBS-PDPS is intended for installations where an Ethernet-based control system must exchange cyclic process data with a PROFIBUS-DP master. It is a practical migration component for legacy drives, remote I/O, analyzers, and machine controllers that cannot be replaced during a modernization project.
The gateway does not make PROFIBUS devices Ethernet-native. The PLC or Ethernet controller still needs the correct gateway definition, data mapping, network settings, and startup configuration. Treat the module as a protocol boundary that requires engineering on both sides.
Technical Specifications
- Manufacturer: HMS Industrial Networks.
- Product family: Anybus X-gateway.
- Model: ABX-EMBS-PDPS.
- Network conversion: Ethernet-side network to PROFIBUS-DP.
- PROFIBUS operating mode: Slave, according to multiple listings.
- PROFIBUS master requirement: The connected PROFIBUS network must provide a compatible DP master.
- Ethernet protocol: Public listings use the general term “Ethernet”; the exact Ethernet protocol and feature set must be confirmed from the unit’s manual and label.
- Configuration: Verify network addressing, GSD/GSDML requirements, cyclic data length, and parameter mapping before commissioning.
- Reported dimensions: Approximately 140 × 110 × 50 mm from a used-equipment listing.
- Reported weight: Approximately 0.5 kg per unit from the same listing.
- Condition availability: Used, refurbished, and new-sealed categories appear in reseller listings, depending on inventory.
- Alternate designation: AB763A-B appears in one used-working listing associated with the model.
Exact electrical ratings, supported Ethernet protocol, connector pinout, maximum PROFIBUS segment parameters, and configuration software were not verified from an official HMS datasheet in the sources reviewed. Obtain the applicable manual before specifying a replacement.
Field Application
A common retrofit situation is a packaging line with an older PROFIBUS-DP network and a newly installed Ethernet-based supervisory controller. Replacing every PROFIBUS node would have required a full shutdown, so the integrator installed the ABX-EMBS-PDPS at the network boundary. The critical work was not the physical mounting; it was matching the mapped input/output byte structure and confirming that the PROFIBUS master accepted the gateway’s configured slave identity.
Useful application scenarios include:
- Connecting a legacy PROFIBUS-DP drive cluster to an Ethernet-based PLC or supervisory control system.
- Integrating PROFIBUS remote I/O into an Ethernet control architecture during a phased plant upgrade.
- Maintaining a machine cell where the upstream controller has changed but the installed PROFIBUS devices remain serviceable.
QA & Testing Transparency
For used or surplus stock, the inspection should cover:
- Confirm the complete model label, serial number, hardware revision, and any alternate identifier such as AB763A-B.
- Inspect the Ethernet and PROFIBUS connectors, housing, mounting points, status LEDs, and terminal areas.
- Power the unit with the manufacturer-approved supply and check startup diagnostics.
- Test Ethernet link establishment and configuration access using the correct engineering procedure.
- Connect the gateway to a compatible PROFIBUS-DP master or approved test station.
- Verify slave recognition, diagnostic status, cyclic data exchange, and representative input/output mapping.
- Issue a test report that clearly distinguishes “tested working,” “inspected only,” “refurbished,” and “new surplus.”
One supplier advertises a used unit with a six-month replacement warranty, while other listings show used or pre-owned stock. Warranty duration and test scope therefore must be confirmed in writing for the specific serial-numbered unit.

Veteran’s Tech Trap Guide
⚠️ Ethernet does not identify the protocol. ABX-EMBS-PDPS listings describe the Ethernet side broadly. Do not assume EtherNet/IP, Modbus TCP, PROFINET, or another protocol without confirming the exact product variant and documentation.
⚠️ The PROFIBUS role is easy to reverse. This model is identified as a PROFIBUS slave. It cannot replace a gateway that requires the PROFIBUS side to act as a master. Check the control architecture before ordering.
⚠️ Byte mapping can quietly break the process. A gateway may show healthy network status while words, bytes, signed values, or status bits are mapped incorrectly. Compare the configured data image against the PLC tags and perform an I/O simulation before connecting live equipment.
PRO TIP: Record the original gateway configuration before removal. Network address settings are often recoverable; the exact cyclic data layout and scaling assumptions may not be.
Dynamic FAQ
What is ABX-EMBS-PDPS?
It is an HMS Anybus X-gateway used to connect an Ethernet-side industrial network with a PROFIBUS-DP slave interface.
Is it a PROFIBUS master?
No. Available listings identify the PROFIBUS side as a slave. The upstream PROFIBUS network must provide a compatible master.
Is AB763A-B the same part?
AB763A-B is listed as an alternate identifier in connection with ABX-EMBS-PDPS, but the relationship should be verified from the nameplate and HMS documentation before treating it as a guaranteed equivalent.
Can it be used with any Ethernet PLC?
Not automatically. The Ethernet protocol, configuration method, data limits, and PLC-side device support must match. Confirm the exact Ethernet variant and required configuration files before purchase.
Is the unit new surplus?
Not necessarily. Market listings include used, pre-owned, refurbished, and new-sealed condition categories. Request photographs, serial information, packaging evidence, and the seller’s written condition statement.
What warranty is available?
Warranty depends on the seller and condition. One listing advertises a six-month replacement warranty, while another industrial reseller advertises a two-year warranty and repair service. Confirm whether the warranty covers configuration-related failures, communication faults, and DOA returns before issuing a purchase order.
