Function & System Integration

CHARM address plugs serve as critical identification components in DeltaV electronic marshalling systems, providing each CHARM module with a unique address for controller communication. The KL4501X1-BC1 with its 1E key position mechanically and electronically identifies CHARM modules, preventing address conflicts and ensuring reliable data exchange between field I/O and DeltaV controllers.

Addressing Architecture: DeltaV CHARM systems support up to 8 address plugs per CHARM I/O carrier, with each plug featuring a distinct key position (1A, 1C, 1E, 3A, 3C, 3E, 5A, 5C). The mechanical keying prevents incorrect plug insertion, while the electronic addressing enables the controller to uniquely identify each CHARM module on the carrier.

System Scalability: Address plugs enable flexible I/O expansion without complex wiring changes. As process requirements grow, additional CHARM modules can be installed with appropriate address plugs, and the DeltaV system automatically recognizes the new I/O points during configuration download.

Industrial Applications

Large-Scale Process Units: In refineries, chemical plants, and power generation facilities with hundreds or thousands of I/O points, address plugs provide systematic organization of CHARM modules across multiple I/O carriers. The 1E key position (Address Plug #3) typically designates specific functional areas or process units within the overall control architecture.

Modular Skid Systems: For packaged equipment skids and modular process units, address plugs enable standardized I/O configurations that can be replicated across multiple installations. Each skid uses consistent address plug assignments, simplifying commissioning and reducing engineering time.

Retrofit & Expansion Projects: When adding I/O capacity to existing DeltaV systems, address plugs allow new CHARM modules to be integrated without disturbing operational I/O. The unique addressing prevents conflicts with existing modules and maintains system integrity during hot-cutover activities.

Redundant I/O Configurations: In critical control applications requiring redundant I/O, address plugs help organize primary and backup CHARM modules. Systematic address plug assignment (e.g., odd numbers for primary, even for backup) simplifies troubleshooting and maintenance procedures.

Address Plug Variant Overview

Installation & Configuration

Address plugs install directly onto CHARM modules before mounting on the CHARM baseplate:

• Pre-Installation: Insert address plug into CHARM module socket, ensuring mechanical key aligns with module keying slot
• Verification: Confirm plug is fully seated and locking mechanism engages to prevent accidental removal
• Module Mounting: Install CHARM module with address plug onto baseplate terminal block assembly
• System Configuration: DeltaV controller automatically recognizes address plug position during I/O configuration download
• Documentation: Record address plug assignments in system documentation for future maintenance and troubleshooting

Maintenance & Spare Parts Strategy

Address plugs are passive components with no wear parts, providing long-term reliability:

• No periodic maintenance or calibration required
• Recommended spare: 1-2 units per address position for emergency replacement
• Store in anti-static packaging to protect electronic components
• Inspect mechanical keying during CHARM module replacement to ensure proper alignment
