Essential details：SS6501T01 DeltaV™ Electronic Marshalling
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.
Benefits
I/O anywhere you need it: DeltaV CIOC provides an unprecedented flexibility in control system I/O topology. Using standard Ethernet infrastructure hardware you can add I/O anywhere you need it. From a local I/O cabinet to remote enclosures miles away, simply install the hardware and connect it to the DeltaV control network. Each I/O card can serve I/O signals to any four controllers in the system with 50-ms updates for fast, reliable control.
Single channel granularity: The CHARM I/O architecture allows each individual channel to be characterized for the requirements of the field device. Any instrument signal can be wired to any terminal block. The channel is then electronically marshalled by installing the appropriate CHARM and assigning the channel to one of four controllers. Home run multi-core instrument cables can be landed in order on a series of CHARM terminal blocks without concern for signal types.
Reduces installed cost of system: DeltaV Electronic Marshalling helps reduce overall system costs by eliminating internal cabinet cross wiring, reducing overall footprint, simplifying I/O channel assignments, and reducing Factory
Authorized Testing activities. Electronic Marshalling provides separation between I&E hardware installation schedules and control strategy development. Wiring can begin earlier knowing any late changes can be done without lifting a wire.
Separation of the controller and I/O allows more efficient cabinet designs and accommodates late scope changes you can add I/O anywhere. Adding additional control capacity does not require re-wiring I/O. Simply assign the control modules and their I/O signals to the new controller, without lifting a wire.

SS6501T01 DeltaV™ Electronic Marshalling
Fully redundant communications: The CIOC architecture is fully redundant. It starts with the two I/O cards on a carrier.
The carrier has redundant communication modules for primary and secondary network connections. There are two 24V DC input power connections. The carrier connects to the CHARMs baseplates and provides redundant power and communication buses to the CHARMs. Everything is redundant down to the individual channel.
Field-mounted capable hardware: All components of the CIOC are rated for installation in Class 1/Div 2 or Zone 2 hazardous locations. The extended operating temperature ranges and G3 environment rating allows them to be installed in field-mounted junction boxes. This further reduces the footprint required in central equipment rooms, as well as reduces the overall wiring infrastructure of traditional multi- core instrumentation cable.
Plug and Play I/O: The DeltaV CIOC has been designed for ease of use, both in physical installation and its software tools. Components snap together with secure DIN-rail latches and interlocking carrier connectors. Attach a series of 96 I/O channels to a DIN-rail in a matter of minutes. Insert the CHARMs and auto sense the node to create the I/O definition automatically in your DeltaV configuration database.
CHARMs use a self keying system to automatically set a channel for a specific CHARM type. Users cannot mistakenly insert a CHARM into the wrong terminal block. Assign all, one or any number of channels to a controller with a simple click or drag and drop.
