Introduction
DeltaV™ Electronic Marshalling delivers a new level of
control system I/O performance with unprecedented flexibility
and ease of use. The CHARM I/O card (CIOC) supports up
to 96 individually configurable channels and is designed
specifically for multi-core home run cables in centrally located
marshalling cabinets. It can also be installed in field junction
boxes to further reduce system design and installation costs.
All communications are completely redundant from the
channel (CHARM) to the DeltaV controller.
