Q&A
Q: How many segments does the CC-PFB401 support compared to the CC-PCF901? A: The CC-PFB401 (FIM2) supports 2 segments, while the CC-PCF901 (FIM4) supports 4 segments.
Q: Does this module provide power to the Fieldbus devices? A: No, the module handles communication only; a separate Fieldbus Power Supply is required to power the devices on the H1 segment.
Q: Is it possible to swap this module while the system is running? A: Yes, in a redundant configuration, the module is hot-swappable without interrupting process control.
