DeltaV™ Electronic Marshalling

Benefits

• I/O Anywhere You Need It: DeltaV CIOC provides unparalleled flexibility in control system I/O topology using standard Ethernet infrastructure. Add I/O anywhere, from local cabinets to remote enclosures miles away, by simply installing the hardware and connecting it to the DeltaV control network. Each I/O card can serve I/O signals to any four controllers 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 field device's requirements. Any instrument signal can be wired to any terminal block and electronically marshalled by installing the appropriate CHARM and assigning the channel to a controller. 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 reduces overall system costs by eliminating internal cabinet cross-wiring, reducing footprint, simplifying I/O channel assignments, and minimizing Factory Authorized Testing activities. It provides separation between I&E hardware installation schedules and control strategy development, allowing wiring to begin earlier. Late scope changes can be accommodated without rewiring. Adding control capacity does not require re-wiring I/O; simply assign control modules and their I/O signals to the new controller.
• Fully Redundant Architecture: The CIOC architecture is fully redundant, starting with two I/O cards on a carrier. The carrier has redundant communication modules for primary and secondary network connections and two 24V DC input power connections. The carrier connects to the CHARMs baseplates, providing redundant power and communication buses to the CHARMs. Redundancy extends down to the individual channel.
• Field-Mounted Capable Hardware: All CIOC components are rated for installation in Class 1/Div 2 or Zone 2 hazardous locations. Extended operating temperature ranges and G3 environment rating allow installation in field-mounted junction boxes, reducing the footprint required in central equipment rooms and the overall wiring infrastructure.
• Plug and Play I/O: The DeltaV CIOC is designed for ease of use in physical installation and software tools. Components snap together with secure DIN-rail latches and interlocking carrier connectors. Up to 96 I/O channels can be attached to a DIN-rail in minutes. Inserting CHARMs auto-senses the node, creating the I/O definition in the DeltaV configuration database. CHARMs use a self-keying system to automatically set a channel for a specific CHARM type, preventing incorrect insertion. All, one, or any number of channels can be assigned to a controller with a simple click or drag and drop.

Product Description

Electronic Marshalling hardware includes:

• CHARM I/O Carrier: DIN rail-mounted, supports a redundant pair of CHARM I/O Cards, redundant 24V DC power connectivity, and redundant Ethernet communication modules.
• CHARM I/O Card (CIOC): Provides communication between CHARMs and the Ethernet I/O network to M-series, S-series, and PK controllers. The CIOC has Achilles Communications Certification Level 1, and the redesigned CIOC2 has Level 2 certification. The CIOC2 is a drop-in replacement for the CIOC (v14.3 or later required).
• CHARM Baseplate: DIN rail-mounted with interleaving power and bus connectors. Supports 12 CHARMs and their terminal blocks, plus connection for injected field power.
• CHARM Terminal Block: Removable terminal block providing terminal connections to field wiring and a physical latch for the CHARM.
• CHARMS: Characterization Module for each field signal, providing basic analog-to-digital conversion and signal isolation to the redundant communication bus.
• Cable Extenders: Provide flexibility in carrier mounting.
• I/O Bus Termination: Provides bus terminations for the redundant I/O bus.
• Labeling Features: Available for baseplate and channel identification to aid maintenance.

Field power is provided through a redundant 24V DC bus to each CHARM, with up to 100 mA per CHARM. Higher current channels can be powered through integrated power injection bus local to each CHARM Baseplate.

Hardware Specifications

*Operating any electronics at the higher end of its temperature range for long periods will shorten its expected lifetime. Refer to the 'Effects of Heat and Airflow Inside an Enclosure' White Paper for more information.

**When used with copper Ethernet I/O Ports (Copper IOP), the operating temperature range is limited to -40 to 60°C (-40 to 140°F).

***When used with all CHARM Types except the DI 120 V AC Isolated Plus CHARM, the operating temperature range is limited to -40 to 60°C (-40 to 140°F).

CHARM Keying Posts

Terminal Blocks contain keying posts that are automatically set and locked to the unique position of the installed CHARM, preventing the insertion of an incorrect CHARM during maintenance. Keys are shipped in a neutral position and set upon CHARM insertion. They can be manually reset to re-task a channel 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 has a unique key setting.

ASCO 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, similar to other CHARMs.

Benefits of the new 580 CHARM Node:

• Redundant communications and power connections to pneumatic valve manifolds.
• Eliminates the need for additional dedicated networks like Profibus-DP, simplifying system I/O mapping.
• Expands Electronic Marshalling I/O to include ASCO Numatics pilot valve manifolds, enhancing the "I/O Anywhere" concept.
• Reduces programming and commissioning time.

System Compatibility

DeltaV Electronic Marshalling hardware requires DeltaV v11.3.1 or later software. Assigning CHARMs to MD Plus, MQ, MX, and PK controllers is supported in DeltaV v14.3 and later. CHARM I/O Card 2 (CIOC2) requires DeltaV v14.3 or later software.

Electronic Marshalling requires the use of DeltaV Smart Switches between controllers and CIOCs. Refer to the 'Network Considerations for M-series with Electronic Marshalling' White Paper for details.
