3Configuring Genius Redundancy on the Redundancy TabGenius redundancy for the Bus Controller can be configured on the Redundancy tabas described below. Genius redundancy for the system can be configured using built-inwizards as explained next in this chapter. The wizards can also be used to configureSeries 90-70 Hot Standby CPU redundancy for specific Series 90-70 CPU models.When configuring a redundant Series 90-70 PLC system, remember to change theLoss of IOC fault from fatal to diagnostic. Otherwise, loss of a Bus Controller willcause the CPU to shut down. (This change can be made in the CPU configuration.)Also, when using Genius redundancy, do not set the CPU’s BackplaneCommunications window (for Series 90-70 CPUs, this is the System Communicationswindow) to 0. When using Constant Sweep mode, be sure to allow enough time for theBackplane Communications window to run. There must be enough time for the BusControllers to exchange information about Genius devices that are lost or added.Selecting the Redundancy ModeSelect the Bus Controller's Redundancy Mode first. Changing the Redundancy Modeselection can reset some or all of the parameters that you have already entered.RedundancyModeThe type of redundancy, if any. See chapter 7 for more detaileddescriptions of redundancy modes. Configuration examples forredundancy are also shown on the following pages.Note: if you set up a Bus Controller for redundancy, then eitherCOPY or UNDELETE the Bus Controller’s configuration, theRedundancy Mode of the copy or restored version is reset toNONE and the Redundancy of blocks on the bus is reset to NO.None: This is the default. None means the Bus Controllercommunicates with a single bus, it is the only controller on the bussending outputs, and no I/O devices on the bus are set up for anytype of redundancy.If, during subsequent configuration of devices on the bus, anydevice is set up for redundancy, Redundancy Mode isautomatically changed to Dual Bus.Similarly, if Redundancy Mode is set to anything except NONE,any devices on the bus that have already been configuredautomatically have their Redundancy parameter set to YES.3-6 Series 90-70 Genius® Bus Controller – July 2003 GFK-2017
3Dual Bus:Select Dual Bus if there are two busses, each of which has its own Bus Controller. TheBus Controllers can be in the same PLC or separate PLCs. Switching devices, usuallyGenius Bus Switching Modules (BSMs), each link up to seven additional devices to thedual busses.BusControllerBusControllerBUS ABUS BBSMBSMCONTROLLERBLOCKUP TO 7 MOREBLOCKSRedundant Controller:Select this for redundant Bus Controllers, either in the same PLC or separate PLCs:CPUCPUBusControllerBusController(Device 31)(Device 30)1234 5GFK-2017 Chapter 3 Bus Controller Configuration 3-7
