This product is AC500 series EtherCAT slave communication expansion module under ABB AC500 PLC control platform, manufactured in compliance with IEC industrial standards and ABB global production specifications. It is a pluggable optional accessory installed on the dedicated CPU expansion slot, adding standard EtherCAT industrial real-time Ethernet interface for the controller to achieve high-speed synchronous data exchange with EtherCAT master controllers, servo drives and distributed field peripheral equipment.

3BDH is fixed internal material coding prefix for ABB AC500 series PLC expansion accessory products.000040 stands for exclusive part serial number of this EtherCAT communication module inside ABB internal product catalog.R1 represents the first hardware revised version with optimized internal circuit design compared with original prototype.

The module obtains working power from CPU internal backplane bus without independent external power supply. The Ethernet interface follows IEEE802.3 standard with 10/100Mbps auto-adaptive transmission rate and conforms to international EtherCAT real-time bus specification. Working ambient temperature ranges from -25℃ to +60℃, storage temperature covers -40℃ to +85℃, protection grade is IP20 for cabinet inner installation. The whole module passes IEC61000 EMC anti-interference and industrial anti-vibration certification.

Front panel is equipped with standard RJ45 Ethernet port for connecting industrial network cable and upper EtherCAT master devices. Rear gold finger plug structure inserts into CPU reserved expansion slot to finish internal data transmission via CPU built-in bus circuit. The module runs as EtherCAT slave station, no built-in RS485 or other fieldbus terminals on module housing.

It expands dedicated real-time EtherCAT communication channel for AC500 main controller. It cyclically uploads digital and analog acquisition data from local I/O modules to upper EtherCAT master station and receives real-time motion and logic control instructions issued by master to drive field executing components. It enables local PLC to access high-speed EtherCAT bus network and satisfy high synchronous control demands of motion automation systems.

It is widely installed inside control cabinets of automated assembly equipment, high-speed packaging machinery, textile spinning equipment and servo-driven production lines, applied for bus connection with all types of EtherCAT-compliant servo drives and distributed field I/O units.

Cut off total power supply of matched CPU before installation, insert the module vertically into CPU expansion slot until mechanical locking is fully completed. Connect standard industrial Ethernet cable into RJ45 port and complete EtherCAT parameter configuration in programming software according to field network layout. Perform routine maintenance every six months, remove dust on port and module shell with dry soft brush and forbid liquid cleaning solvent. Replace the entire module when persistent communication abnormality exists after eliminating external wiring and master equipment faults, unauthorized disassembly and internal circuit modification are prohibited.
