FAQs
Q1: What is the primary function of the PM5650-2ETH?
It is a mid-tier processor module in the AC500 V3 series, responsible for executing user programs, managing I/O communication, and handling all control logic in standard to complex automation systems. With 80 MB user memory and a 600 MHz processor, it is designed for applications requiring solid performance and flexible communication .
Q2: What communication protocols are supported onboard?
The module includes 2 independent Ethernet interfaces (Modbus TCP, OPC UA, IEC 60870-5-104, 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 PM5650-2ETH 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 is available with communication modules.
Q4: What is the difference between PM5650-2ETH and PM5670-2ETH?
The PM5670-2ETH has 160 MB user memory and a 1 GHz processor, while the PM5650-2ETH has 80 MB memory and a 600 MHz processor. The PM5670 offers higher performance and larger memory for more demanding applications, but both share the same communication interfaces and local I/O expansion capabilities.
