ABB Symphony Harmony/INFI 90 DCS Remote I/O Module Upgrade Kit

ABB Symphony Harmony/INFI 90 DCS Remote I/O Module Upgrade Kit

Overview of Upgrade Kit

ABB has launched a remote I/O module upgrade kit for the Symphony Harmony/INFI 90 process control system, which includes a new low-cost IMRIO22 module aimed at providing continuous lifecycle support for the system and addressing various issues with existing systems.

Solve the problem

Components are outdated and new parts are no longer available.

The cost of replacing parts is high.

The ability to repair parts has decreased.

The electrical remote communication chain is affected by noise and lightning strikes.

Difficult to troubleshoot remote I/O issues.

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

Controller configuration requires the use of multiple segment control blocks for special "adjustments".

IMRIO02 has firmware compatibility issues with some I/O modules.

Be extra cautious when replacing system components.

Advantages of the plan

Reliability improvement: Updated technology has been adopted to enhance fiber optic communication.

Spare parts availability: Provide new replacement parts.

Easy to replace: Compatible with existing remote I/O settings, with the same rack size, can use existing fiber optic cables, IMRIO22 replaces IMRIO02 in remote cabinets.

Reduce cabinet space occupation: IMRIO02 in the local cabinet is no longer needed, and its functions are integrated into BRC300/400, replacing the existing MFP or MFC controllers in the local cabinet with BRC.

Control performance improvement: increased memory capacity, faster execution and communication speed.

Improved communication link and remote I/O update speed.

Hardware/firmware compatibility improvement: better compatibility between remote I/O processors and remote I/O modules.

Easy firmware upgrade: The IMRIO22 module has flash memory.

Redundancy enhancement: Faster fault detection/switching speed from primary IMRIO22 to backup IMRIO22.

Error checking and diagnostic improvement: facilitates troubleshooting.

Redundant HNET remote communication channel.

Minimum System Requirements

The BRC300/400 controller requires a Process Bus Adapter (PBA), which needs to be added if it is not present.

Composer engineering tool version 5.0 or higher.

Fiber optic cable (62.5/125 micron multimode) for remote links.

Restrictive conditions

Only supports fiber optic point-to-point communication links.

The electrical link (dual axis or coaxial cable) must be replaced with optical fiber.

Serial or Daisy Chain multi-point links are not supported, and multi-point connections for multiple remote cabinets (up to 6) now require a star configuration from the local cabinet.

Upgrade package content

Non redundant configuration: Part number INRIOK01

Redundant configuration: Part number INRIOK02

Harmony remote I/O module: 1, 2 IMRIO22

Process bus adapter: 1, 2 PHCBRCPBA20000

HNET fiber optic repeater terminal unit: 4, 4 NTRL04

HNET's process bus adapter cable: 2, 2 PMKHRMPBA1T004

HNET Bus Terminators: 4, 4 PHAMSCTER30000

Redundant cables for bridge controller: 0, 1 PMKHRMBRC3000A

Note: The multi-point remote I/O architecture will require inter column connection cables to daisy chain additional terminal units in the local cabinet.

System/application compatibility

The remote I/O function is compatible with all other existing functions of the Harmony BRC300/400 or higher version controller, including but not limited to:

Supports multiple remote I/O links.

Supports mixed I/O types, such as IOR/S800, Harmony rack I/O, and Harmony module I/O.

Existing fiber optic remote link cables can be reused.
