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

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

DESCRIPTION

As part of ABB’s continued lifecycle support for Symphony Harmony/INFI 90 process control systems, a Remote I/O  Module Upgrade Kit with a new, low-cost IMRIO22 module is now available.

Problems solved with Remote I/O upgrade kit

− Component obsolescence, new parts are no longer available 

− Cost to replace parts is high 

− Decreasing ability to repair parts 

− Electrical remote communication links are susceptible to noise; lightning strikes 

− Difficult to troubleshoot remote I/O problems 

− Link is slow; takes time for I/O points to update

− Controller configuration requires special “tuning” using multiple segment control blocks 

− Firmware compatibility issues between IMRIO02 and some I/O modules 

− Must be careful when replacing parts in the system

Benefits

− Reliability; newer technology, improved fiber optic communications 

− Availability of new replacement parts 

− Easy to replace the existing remote I/O setup 

– same rack form factor; uses existing fiber optic cables; the RIO22 replaces the RIO02 in the Remote cabinet 

− Reduced cabinet footprint as the RIO02 in the Local cabinet is no longer required; its functionality is now included in a BRC300/400. The BRC replaces existing MFP or MFC controllers in the Local cabinet 

− Improved control performance - increased memory capacity, faster execution and communication speeds 

− Improved speed of communication link and remote I/O updates 

− Improved hardware/firmware compatability between remote I/O processor and remote I/O modules 

− Easier firmware upgrades; IMRIO22 module has flash memory 

− Improved redundancy; faster detection/failover from primary to backup IMRIO22 

− Improved error-checking and diagnostics for troubleshooting 

− Redundant HNET remote communication channels

Minimum System Requirements

− BRC300/400 controllers require Process Bus Adapters (PBA). Please add these if they do not currently exist 

− Composer Engineering Tools version 5.0 or later 

− Fiber optic cable (62.5/125 micrometer multimode) for remote link

Restrictions/Limitations

− Supports only fiber optic point-to-point communication links 

− Electrical links (twin axial or coaxial cable) must be replaced with fiber optic 

− Serial or daisy chain multi-drop links are not supported; multiple drops to remote cabinets (up to 6) now require a star configuration from the Local cabinet

System/Application Compatibility

The remote I/O functionality is compatible with all other existing features of the Harmony BRC300/400 or later controllers. This includes, but is not limited to, the following:

− Support for multiple remote I/O links 

− Support mixed I/O types, e.g. IOR/S800, Harmony Rack I/O, Harmony Block I/O 

− Re-use of existing fiber optic remote link cables
