Communication Modules
Industrial communication modules provide interconnection and real-time data exchange between your PLCs, variable speed drives and field devices.
Whether network expansion cards (PROFINET, EtherNet/IP, PROFIBUS) or specialised interfaces for motion control units, they ensure fast, deterministic transmission of setpoints and diagnostics.
Discover our selection of certified and refurbished interface and network expansion modules (Lenze, Gema, Siemens, Schneider) to ensure interoperability and maintenance of your automation architectures.

FAQ
A communication module (such as the Lenze PROFINET E84AYCERV/S card for the 8400 range) integrates a standalone device (drive, axis, instrument) into a plant-wide industrial network. It converts the setpoints sent by the central PLC into direct control commands for the device.
Faults most often appear as repeated loss of the fieldbus, a steady or flashing network error LED (BF/SF or Net-Err), inability to exchange control words with the PLC, or the module not being detected at all when the configuration (GSD/GSDML file) is sent.
Yes, we offer component-level repair of your network cards and communication interfaces. Replacing bus chips (PHY transceivers), internal voltage regulators or network connectors (RJ45, Sub-D) restores the card without replacing the associated drive or controller.
For most communication modules, replacement only requires setting the address DIP switches or assigning the device name/IP address via the PLC or the manufacturer's commissioning software, so the line can be restarted very quickly.
