- Diagnostics: Providing engineering access for troubleshooting and logic forcing.
Product Q&A
Q: Is the MMI301 compatible with the newer Mark VIe system? A: The MMI301 is primarily designed for the Mark VI VME-based platform. For Mark VIe systems, different UCSB or UCSC controllers with integrated Ethernet are typically used.
Q: Does this module require specific HMI software? A: Yes, it is typically used in conjunction with GE’s CIMPLICITY software or the TCI (Turbine Control Interface) to translate rack data into graphical displays.
Q: Can the MMI301 be hot-swapped during turbine operation? A: While the hardware supports it, it is recommended to perform replacements during a scheduled maintenance window to avoid losing visibility of the process on the operator screen.
