FAQs
Q1: What is the primary function of the PM5630-2ETH?
It is an entry-level processor module in the AC500 V3 series, responsible for executing user programs, managing I/O communication, and handling control logic in basic automation systems. With 8 MB user memory and 0.02 µs instruction cycle time, it is designed for simple machine control, building automation, and small-scale process applications .
Q2: What communication protocols are supported onboard?
The module includes 2 independent Ethernet interfaces (Modbus TCP, IEC 60870-5-104, DNP3, EtherNet/IP, BACnet, KNX IP controller functions), 1 serial port (RS-232/RS-485, Modbus RTU/ASCII), and 1 CAN port (CANopen Master/Slave, J1939, CAN 2A/2B) . Additional fieldbus protocols (PROFIBUS, PROFINET) are supported via optional communication modules .
Q3: What is the difference between Revision 2 and Revision 3?
Revision 3 (R0378) replaces Revision 2 (R0278) and provides the same functionality. However, Revision 3 requires System Firmware V3.6.x or higher and Automation Builder 2.6.0 or later. Existing applications built with older Automation Builder versions must be upgraded to at least AB 2.6.0 before running on Revision 3 hardware .
Q4: How much I/O can be connected locally?
The PM5630-2ETH 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 optional communication modules.
