HMS AB7697-F Replacement Solution for Anybus Communicator

Product Overview

HMS AB7697-F Replacement Solution for Anybus Communicator: Seamless PROFIBUS DP to DeviceNet Migration

The HMS Networks AB7697-F is a proven Anybus Communicator gateway that bridges PROFIBUS DP master networks to DeviceNet slave devices — a critical link in legacy automation architectures across automotive assembly lines, process plants, and discrete manufacturing cells. As HMS Networks continues to evolve its Anybus product portfolio, many facilities running older Anybus Communicator units face the challenge of sourcing verified replacements before their installed base reaches end-of-life. TOPNLMS maintains ready stock of the AB7697-F to support your retrofit, upgrade, or emergency replacement requirements with zero compromise on compatibility.

Whether your existing gateway has failed in service, your maintenance team is building a critical spare inventory, or your engineering department is planning a phased migration from a legacy fieldbus architecture to a more modern network topology, the AB7697-F delivers the exact electrical, mechanical, and protocol-level compatibility your system demands. Every unit shipped by TOPNLMS is individually tested against PROFIBUS DP and DeviceNet communication standards before dispatch, and is backed by a 12-month replacement warranty.

Seamless Upgrade Solutions

A successful migration from a legacy PROFIBUS DP / DeviceNet architecture to a modernized control system rarely involves a single component swap. In practice, field engineers replacing an AB7697-F gateway often encounter adjacent components that require simultaneous attention. During commissioning, the PROFIBUS DP segment typically connects upstream to a Siemens S7-300 or S7-400 PLC CPU module via a CP 342-5 or CP 443-5 communications processor, and the DeviceNet side interfaces with distributed I/O nodes such as Allen-Bradley 1734 POINT I/O or 1756 ControlLogix I/O modules. Ensuring that the gateway’s GSD file is correctly imported into the PROFIBUS master configuration — whether in STEP 7, TIA Portal, or RSLogix 5000 — is a prerequisite for stable data exchange after replacement.

On the DeviceNet side, the AB7697-F operates as a DeviceNet slave. If the DeviceNet master is an Allen-Bradley 1756-DNB DeviceNet Scanner module or a 1771-SDN Scanner, the EDS file for the AB7697-F must be registered in RSNetWorx for DeviceNet before the replacement unit is brought online. In installations where the DeviceNet trunk cable runs through a control cabinet alongside a 1606-XLP power supply or a Phoenix Contact QUINT power supply unit, the 24 VDC feed to the AB7697-F can be tapped from the same bus bar without modification, provided the total current budget is within specification.

For facilities that are simultaneously upgrading their PROFIBUS DP infrastructure, the AB7697-F pairs naturally with HMS Anybus X-gateway products that support PROFINET or EtherNet/IP on one side, enabling a phased migration where the DeviceNet field devices remain in service while the upper network layer is modernized. In such architectures, signal isolators — such as those from the Pepperl+Fuchs or Phoenix Contact range — are sometimes inserted on the PROFIBUS segment to protect the gateway’s RS-485 interface from ground loops introduced during partial rewiring. Anybus Configuration Manager software, available as a free download from HMS Networks, is used to map the I/O data between the two network sides and must be re-run after any hardware replacement to verify that the data offset configuration matches the PLC program’s expectation.

Where the control cabinet layout is constrained, the AB7697-F’s compact DIN rail form factor — identical to earlier Anybus Communicator revisions — means that no panel modifications are required. The terminal block wiring for the PROFIBUS DP connector (DB9 or screw terminal, depending on installation) and the DeviceNet open-style connector can be transferred directly from the failed unit to the replacement without re-labeling or re-routing. This is a significant advantage in time-critical maintenance windows where minimizing downtime is the primary objective.

Retrofit Guidance FAQ

Q: Can I reuse my existing PROFIBUS DP wiring when replacing the AB7697-F?
A: Yes. The AB7697-F uses a standard PROFIBUS DP DB9 or screw-terminal interface. Your existing shielded twisted-pair cable, termination resistors, and bus connectors are fully compatible. Verify that the PROFIBUS station address (set via rotary switches on the unit) matches the address configured in your PLC master.

Q: Do I need to update the PLC program after replacing the gateway?
A: In most cases, no. If the replacement AB7697-F is configured with the same I/O data size and station address as the failed unit, the PLC program requires no modification. Re-import the GSD file into your PROFIBUS master configuration tool and perform a hardware comparison to confirm the I/O mapping is unchanged.

Q: Is the AB7697-F compatible with all DeviceNet master scanners?
A: The AB7697-F is ODVA-certified and compatible with all standard DeviceNet master scanners, including Allen-Bradley 1756-DNB, 1771-SDN, and third-party scanners from Omron, Mitsubishi, and Beckhoff. Register the EDS file in your network configuration tool before bringing the replacement unit online.

Q: What is the maximum I/O data size supported?
A: The AB7697-F supports up to 244 bytes of input data and 244 bytes of output data, configurable via Anybus Configuration Manager. Ensure the data size configured in the replacement unit matches the original configuration to avoid I/O mapping errors in the PLC.

Q: How long does commissioning typically take after a direct replacement?
A: For a direct drop-in replacement with no configuration changes, experienced field engineers typically complete commissioning — including power-up, communication verification, and PLC online test — within 30 to 90 minutes. Allow additional time if the Anybus Configuration Manager project file needs to be re-applied or if the DeviceNet EDS file must be re-registered.

Q: Can the AB7697-F be used in a system where the PROFIBUS DP master is a Siemens S7-1500 with TIA Portal?
A: Yes. Import the AB7697-F GSD file into TIA Portal’s hardware catalog, configure the PROFIBUS DP slave parameters to match your I/O requirements, and compile the hardware configuration. The AB7697-F is fully compatible with S7-1500, S7-300, and S7-400 PROFIBUS DP masters.
