FAQs
Q1: What is the primary function of the PM5675-2ETH?
It is the flagship processor module of the AC500 V3 series, responsible for executing user programs, managing I/O communication, and handling all control logic in complex automation systems. With 160 MB user memory, 1 GHz multi-core processor, and 8 GB flash disk, it is designed for demanding applications requiring high-speed processing and large data storage.
Q2: What communication protocols are supported onboard?
The module includes 2 independent Ethernet interfaces (Modbus TCP, OPC UA, IEC 60870-5-104, DNP3, HTTP/HTTPS, FTP, SMTP, NTP), 1 serial port (RS-232/RS-485, Modbus RTU, ASCII), and 1 CAN port (CANopen Master, J1939, CAN 2A/2B) . Additional fieldbus protocols (PROFIBUS, PROFINET, EtherCAT) are supported via optional communication modules.
Q3: How much I/O can be connected locally?
The PM5675-2ETH supports up to 10 S500/S500-eCo I/O modules on the local I/O bus, providing a maximum of 320 digital inputs/outputs or 160 analog inputs/outputs . For larger systems, decentralized I/O via fieldbus (PROFIBUS, PROFINET, EtherCAT) is available with communication modules.
Q4: Does this CPU support motion control?
Yes. The PM5675-2ETH supports PLCopen motion control via onboard CANopen or optional EtherCAT communication modules. With an EtherCAT CM, typical synchronized axes are supported at 0.5 ms cycle time . It also supports CAN Sync for simpler motion applications.
Q5: What are the ordering and lifecycle details?
The PM5675-2ETH is available under part number 1SAP151500R0378 and requires System Firmware 3.1.0 or higher . The module is Active in the ABB lifecycle catalog. A terminal base (TB5610-2ETH or TB5620-2ETH) must be ordered separately . Distributor pricing varies significantly, from approximately $180 USD** (surplus/low-cost channel) to **$10,664 USD (official/pre-order channel).
