Whether you are retiring an end-of-life gateway or expanding a legacy network, this module delivers a verified, drop-in migration path that preserves your existing wiring topology while unlocking modern diagnostic and throughput capabilities.

Engineered for industrial environments demanding deterministic communication, the 700-600-CAN12 supports CANopen master/slave configurations and is fully compatible with standard DIN-rail mounting footprints ¡ª eliminating costly panel re-engineering. Target users include system integrators, OEM machine builders, and plant maintenance teams managing multi-vendor automation landscapes.

Compatibility Comparison Table

Seamless Upgrade Solutions

A successful migration to the 700-600-CAN12 often requires verifying or updating adjacent components in your control cabinet. When replacing your legacy CAN gateway, ensure the following companion modules are at compatible firmware and hardware revisions:

• ? CAN Network Processor (CPU) ¡ª Verify your CPU module supports CANopen master at 1 Mbps. The Bachmann ME203/CN CPU Processor Module provides proven CAN + Ethernet co-processing for multi-protocol environments.
• ? Ethernet-Enabled CPU Backup ¡ª For redundant architectures, the Bachmann ME203/EN Processor Module offers identical CAN support with an additional Ethernet port for SCADA connectivity.
• ? CANopen I/O Expansion ¡ª When the 700-600-CAN12 is deployed as a CANopen master, pair it with the Bachmann DIO264-C-A60 64-Channel CANopen Slave for scalable digital I/O without additional gateways.
• ? Fieldbus Bridge (PROFIBUS DP) ¡ª If your upstream PLC communicates via PROFIBUS, the ABB CI830 Profibus DP Communication Module bridges the 700-600-CAN12 network to AC800M controllers at up to 12 Mbps.
• ? Fieldbus Module (Alternate) ¡ª For installations using ABB 800xA DCS, the ABB FI810F Fieldbus Module provides a compatible interface layer between the CAN 300 PRO segment and the process control network.
• ? ModuleBus Fiber Optic Modem ¡ª Long-distance cabinet-to-cabinet CAN runs benefit from the ABB TB840A ModuleBus Cluster Modem, which eliminates ground loop interference on extended CAN segments.
• ? 24V DC Power Supply ¡ª Ensure stable bus power during the upgrade window. The ABB SD822 24V DC 5A Power Supply Module is rated for continuous industrial duty and supports hot-swap scenarios.
• ? PLC Processor (AC500 Series) ¡ª If the migration involves upgrading the host PLC, the ABB PM573-ETH Processor Module (AC500, 512KB, Ethernet) natively supports CANopen master configuration compatible with the 700-600-CAN12.
• ? High-Speed I/O PCB ¡ª For time-critical motion or safety loops on the same backplane, the ABB UNS 0883A-P Fast I/O PCB Board handles sub-millisecond scan cycles without impacting CAN bus throughput.
• ? PROFIBUS DP Interface (Alternate Variant) ¡ª For sites with mixed PROFIBUS and CAN topologies, the ABB CI830 12Mbps AC800M Interface provides a secondary PROFIBUS DP port to maintain legacy device connectivity during phased rollouts.

Retrofit Guidance FAQ

Q1: Can I reuse existing CAN bus wiring when installing the 700-600-CAN12?

Yes. The 700-600-CAN12 uses standard 9-pin Sub-D CAN connectors (ISO 11898). Existing twisted-pair cabling rated for 1 Mbps is fully reusable. Verify termination resistors (120¦¸) are present at both ends of the bus segment before powering up.

Q2: Which programming tools are compatible with the CAN 300 PRO?

The module is configurable via SYCON.net (HMS Networks), Siemens STEP 7 (GSD file import), and TIA Portal V15+. Legacy configuration files from the previous CAN 300 generation can be imported with minor parameter adjustments ¡ª no full re-programming is required in most cases.

Q3: Does the 700-600-CAN12 fit in the same DIN-rail slot as the previous CAN 300?

Physical dimensions are identical (35mm DIN-rail, standard width). No panel cutout modifications are needed. Confirm the backplane connector pinout matches your specific rack revision before installation.

Q4: How do I handle node address conflicts during migration?

The CAN 300 PRO supports node address assignment via rotary switch (hardware) or software override. During phased migration, assign the new module a temporary node ID outside the active range, commission it, then reassign the final address during the scheduled maintenance window.

Q5: What happens to my existing CANopen device profiles (DS401/DS402)?

The 700-600-CAN12 natively supports DS301, DS401 (I/O), and DS402 (drives) profiles. Existing EDS files from your CANopen slaves are imported directly into SYCON.net ¡ª no profile re-mapping is required.

Q6: Is the module compatible with third-party PROFIBUS masters?

Yes. The PROFIBUS DP interface on the CAN 300 PRO is fully compliant with EN 50170 and works with any DP master (Siemens, ABB, Schneider, Beckhoff). Import the provided GSD file into your master configuration tool to complete integration.
