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
Remote I/O Module Upgrade Kit
− Part number INRIOK01 (for non-redundant configuration).
− Part number INRIOK02 (for redundant configuration).
