Selection criteria
Confirm CODESYS V3, PROFINET IO and EtherCAT master architecture matches the machine. Check address-volume, module count and network topology against the full CPX-E design. Verify 24 VDC PELV supply, current demand and terminal-conductor requirements. Apply IP20 and temperature/mounting-position limits from the exact data sheet.
Installation, commissioning and maintenance
Mount on DIN rail in a protected control cabinet and wire the spring terminal per the official data sheet/manual. Observe PELV, EMC, grounding and network-separation practices. Load the validated CODESYS project and GSDML/network configuration; verify PROFINET and EtherCAT diagnostics. Test I/O, motion/fieldbus communication and machine interlocks before production release. Retain CODESYS project and firmware/configuration backups; inspect DIN-rail seating, terminals, RJ45 links and diagnostic logs.
