This product is AC500 series OPC UA / Industrial Ethernet communication expansion module belonging to ABB AC500 PLC platform, manufactured in accordance with IEC industrial standards and ABB global production specifications. It is a pluggable optional component installed on the dedicated CPU expansion slot, adding independent high-speed Ethernet interface to realize OPC UA server/client data interaction and conventional Modbus TCP communication between local PLC and upper monitoring system, industrial HMI and remote management equipment.

3BDH is fixed internal material coding prefix for ABB AC500 series PLC expansion accessory products.000050 is exclusive part serial number of this OPC UA Ethernet module inside ABB internal product catalog.R1 stands for the first hardware revised version with optimized internal communication circuit compared with original prototype design.

The module obtains working power from CPU internal backplane bus without independent external power supply. The Ethernet interface complies with IEEE802.3 standard with 10/100Mbps auto-adaptive transmission rate and supports standard OPC UA and Modbus TCP protocol specifications. 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, switches and upper-level control devices. Rear gold finger plug structure inserts into CPU reserved expansion slot to finish internal data transmission via CPU built-in bus circuit. No built-in RS485 or dedicated fieldbus wiring terminals are arranged on module housing.

It expands exclusive industrial Ethernet channel supporting OPC UA and Modbus TCP for AC500 main controller. It uploads real-time production data, operating parameters and fault alarm information from PLC to upper SCADA, industrial cloud platform and remote control terminals via OPC UA protocol. It also receives remote parameter modification and control instructions from upper devices, realizing transparent cross-platform data exchange for intelligent factory information interconnection.

It is widely equipped inside automation control cabinets of intelligent water treatment projects, packaging automatic production lines, building intelligent monitoring, food processing equipment and factory digital transformation projects, applied for on-site equipment networking and upper information system data docking.

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 configure IP address and OPC UA communication parameters in PLC programming software according to field network requirements. 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 network communication fault exists after eliminating external wiring and upper device faults, unauthorized disassembly and internal circuit modification are prohibited.
