Emerson DeltaV™ Electronic Marshalling CHARM Keying Posts

CHARM Keying Posts

The Terminal Blocks contain keying posts that are

automatically set and locked to the unique position of

the installed CHARM. The keys prevent the insertion of an

incorrect CHARM during maintenance activities. They are

shipped in a neutral position and are set when a CHARM is

inserted. If needed, the keys can be manually reset to allow

a channel to be re-tasked for a different signal type.

The keying mechanism consists of two keying posts that

rotate and lock into the terminal block base. Each CHARM

type is assigned a unique key setting.

Numatics 580 CHARM Node

The 580 CHARM node enables Easy solenoid valve

integration into DeltaV with Electronic Marshalling. The

new 580 CHARM node connects directly to the CIOC via

redundant CHARM Baseplate extender cables. DeltaV can

autosense the I/O as DO Solenoid Valve CHARMs the same

way as any other CHARM is autosensed in DeltaV.

Benefits of the new 580 CHARM Node include:

Redundant communications and power connections to

pneumatic valve manifolds.

Eliminates the need for additional dedicated networks

like Profibus-DP and simplifies system I/O mapping.

Expands the Electronic Marshalling I/O offering to include

ASCO Numatics pilot valve manifolds, enhancing the

concept of: “I/O Anywhere”.

Reduces programming and commissioning

time dramatically.
