Expert Support: Terminal Base & System Integration
Choosing the right communication interface is only half the battle. Ensuring compatibility with the correct Terminal Base (TU) is critical for system stability. Our engineering team provides full guidance for:
• Ethernet Modules: Pair your CI501-PNIO or CI522-MODTCP with the TU508-ETH terminal unit for high-speed network reliability.
• Fieldbus Modules: Use TU510 or TU518 for robust connection with CI541-DP and CI581-CN.
We offer comprehensive configuration checks to ensure your purchase integrates perfectly into your existing PLC architecture.
