System Architecture & Signal Flow
The PMAC2A-ETH 603871-108 operates as the central motion controller within a distributed automation architecture. The host PC or PLC communicates with the board via Ethernet TCP/IP using Delta Tau’s PCOMM32PRO library or direct socket commands. The DSP executes real-time servo algorithms, generating ±10 V analog command signals to servo drives. Encoder feedback is received directly on-board, closing the position loop at the controller level. Digital I/O lines interface with limit switches, home sensors, and auxiliary machine signals. The board supports background PLC program execution in parallel with foreground motion programs, enabling complex machine sequencing without host intervention.

Technical FAQ
Q: Is the PMAC2A-ETH 603871-108 compatible with my existing PMAC2A system?
A: Yes, the PMAC2A-ETH is designed as a direct upgrade for PMAC2A installations. The Ethernet interface replaces the legacy serial/USB connection. Verify your backplane revision and firmware version for full compatibility.
Q: What software is required to program and commission this board?
A: Delta Tau PEWIN32PRO2 (PMAC Executive Pro 2) is the primary programming environment. PCOMM32PRO library is required for host PC communication via Ethernet.
Q: Can this controller support closed-loop servo control?
A: Yes. The PMAC2A-ETH closes the position loop on-board using encoder feedback, providing high-bandwidth servo control independent of the host PC.
Q: Do you provide a test report or inspection certificate?
A: A functional test report is available upon request. For regulated industries, additional traceability documentation can be arranged.
Q: What is the warranty period?
A: All tested surplus units carry a 90-day warranty covering functional defects. Extended warranty options are available for volume orders.
