These portions of the system may receive status from TÜV or non-TÜV approved , including certain other Genius blocks, non-approved rack-based modules, or any other allowable Genius and Series 90 Family components not specifically approved for use in a safety application. 5-14 Genius® Modular Redundancy Flexible Triple Modular Redundant (TMR) GFT-177A System Technical Product Overview – February 1998 5 System Data Types Supported, and Typical Use in a GMR System In order to process information, execute logic comparisons, and move information within the CPU, several data types are available for use in the GMR application program. The table below indicates the various types and notation used for the referenced bit and word–oriented operations. It also indicates which memory types can potentially be written to by a communications module. The ability to exchange data between DCS systems, field bus systems, computer and other intelligent host devices, as well as slave devices is important for any technically– current system. By default, all memory areas are write– protected.
