Options for output devices in a GMR system include: Single, hot standby outputs. Single voted outputs. H–pattern group for fault–tolerant, failsafe outputs. T–pattern group for fault tolerant outputs. I–pattern group failsafe for shutdown outputs. A single block in GMR mode receives outputs from all CPUs and performs voting (2 out of 3, 2 out of 2, or 1 out of 2). For Hot Standby redundancy, a load must be connected to one sink-type or source-type discrete Genius block. Blocks in Hot Standby mode receive outputs from all GMR CPUs and use the output data from the CPU with the Bus Controllers at the highest serial bus address (31, 30, 29) that are currently online. Output loads that must be both failsafe and fault-tolerant are connected to a standard “H” pattern group of two parallel source-type blocks and two parallel sink-type blocks. A T-pattern output group can provide fault–tolerant operation with two parallel sink-type or source-type blocks. This type of group might be used in high-availability or fire–and–gas applications where it is necessary to be able to turn ON a critical load. An I-pattern output group can provide failsafe operation with one sink–type and one source-type block wired in series with a load. This type of group might be used in failsafe applications where it is necessary to be able to turn OFF a critical load. Non-critical outputs can be wired to individual discrete or analog blocks. Such blocks can be configured for no redundancy, or for one of the three CPU redundancy modes: Hot Standby, Duplex or GMR (2 out of 3). For clarity, the illustrations show only one output load connected to a single block or to a group of blocks. However, each block or group of blocks can control outputs to 16 or 32 loads, depending on the block type. Single Genius block Block receives command from all PLCs For Hot Standby redundancy, a load must be connected to one sink-type or source-type discrete Genius block. Blocks in Hot Standby mode receive outputs from all GMR CPUs and use the output data from the CPU with the Bus Controllers at the highest serial bus address that are currently online.
