ABB Symphony Harmony/INFI 90 DCS Remote I/O module upgrade kit

ABB Symphony Harmony/INFI 90 DCS Remote I/O module upgrade kit

Product positioning and problem solving

This upgrade kit is part of ABB's lifecycle support for Symphony Harmony/INFI 90 process control systems, with the core component being a new low-cost IMRIO22 module designed to address the following issues:

Components are outdated and new parts are difficult to obtain

High cost of parts replacement and decreased maintenance capability

Electrical remote communication chain is affected by noise and lightning strikes

Difficulty in troubleshooting remote I/O issues

Slow communication link speed and time-consuming I/O point updates

Controller configuration requires special "tuning" using multiple control blocks

IMRIO02 has firmware compatibility issues with some I/O modules

System component replacement requires extra caution

The advantages of upgrading the kit

Reliability Enhancement: Adopting updated technologies to improve fiber optic communication and reduce interference effects.

Spare parts availability: Provide brand new replacement parts to address outdated issues.

Easy installation: compatible with existing remote I/O settings, with the same rack size, can reuse existing fiber optic cables, IMRIO22 directly replaces RIO02 in remote cabinets.

Space optimization: RIO02 no longer needs to be used in the local cabinet, and its functions are integrated into BRC300/400 (replacing MFP or MFC controllers in the local cabinet), reducing cabinet footprint.

Performance Enhancement: Increased memory capacity, improved execution and communication speed, faster communication link and remote I/O update speed.

Compatibility and maintainability: Improve the hardware/firmware compatibility of remote I/O processors and modules. The IMRIO22 module uses flash memory, making firmware upgrades easier.

Redundancy and Fault Tolerance: Improved redundancy capability, faster switching between primary and backup IMRIO22, enhanced error detection and diagnostic functions for easy troubleshooting, and equipped with redundant HNET remote communication channels.

System requirements and limitations

Minimum system requirements:

The BRC300/400 controller needs to be equipped with a Process Bus Adapter (PBA). If it is not equipped, an additional one needs to be added

Composer engineering tool version 5.0 or higher

Remote links require the use of 62.5/125 micron multimode fiber optic cables

Restrictions:

Only fiber optic point-to-point communication links are supported, and electrical links (dual axis or coaxial cables) must be replaced with fiber optic cables

Serial or daisy chain multi drop links are not supported. Multiple remote cabinets (up to 6) require a star configuration starting from the local cabinet
