3Error RateThis entry determines how the Bus Controller will respond to errors on thebus. If the Bus Controller should drop off the bus when a specified number oferrors occurs within a 10-second period, enter that number of errors here. Ifthe Bus Controller should remain on the bus when errors occur and try tomaintain communications, enter 0 here.CautionIf the bus includes a Bus Switching Module (BSM) or another device thatcontrols bus switching, the Error Rate MUST be set to 0. Otherwise, the BusController may drop off the bus when the BSM is switching a device to thebus.If the error rate is set to 0, the Bus Controller will use a rate of 10 errors in 10seconds. If the detected error rate exceeds 10, the Bus Controller will remainon the bus and flash the Communications LED. The LED will continue toflash until the number of detected errors is less than 10 errors in 10 seconds.If the error rate is set to a value greater than 0, the Bus Controller will monitorthe bus for errors. If the number of errors exceeds the configured error rate,the Bus Controller will turn off the Communications LED and drop off the bus.The Bus Controller will remain off the bus until the number of detected errorsis less than the configured error rate.ReferenceAddressCheckI/O Scan SetThis entry can be used to verify that references already configured fordevices on the Genius bus match the status references assigned to the samedevices with the programmer software. If ENABLED, references are checkedfor all configured devices except PowerTRAC blocks or “GENA”-based busdevices. This feature will not detect or configure an unconfigured device, orcorrect references that do not match.The Scan Set (as defined in the CPU's Scan Sets tab) assigned to thismodule. This can be used only on RX7i and on Release 7 or later 900-series90-70 CPUs. For all other CPUs, leave this field at its default setting (1).3-4 Series 90-70 Genius® Bus Controller – July 2003 GFK-2017
3Configuring Global DataSelect the Global Data tab to configure the Bus Controller to send Global Data.ConfigurationModeFrom AddressData Length(Read-only) the Configuration Mode is always Manual.Specify the beginning PLC address from which data will be transmittedon the bus. It can be from %I, %Q, %G, %R, %AI, or %AQ memory.This entry specifies the amount of Global Data to be sent each bus scan.If Global Data will not be used, set Data Length to zero.If bit-oriented memory (%I, %Q, or %G) is selected, this may be 0 to1024 bits. It must be a multiple of 8. If you enter a number that is not amultiple of 8, the software will automatically adjust it upward to the nexthighest multiple of 8. For example, any number between 9 and 15 wouldbe automatically adjusted upward to 16.If word-oriented memory (%AI, %AQ, or %R) is selected, this may be 0to 64 words. If more than 64 words are selected, the softwareautomatically adjusts the length to 64 words. The total amount ofmemory specified must not exceed the configured memory size for thatmemory type.For example, if %R00001 is selected for From Address and the DataLength is set to 4, the block of data would consist of %R00001 through%R00004.To (Optional)If the data is going to be sent to another Series 90-70 Bus Controller, thisentry is not needed. The destination memory address is specified as partof the target device's configuration.If the data is going to be transmitted to a Series Six PLC or a Series FivePLC, enter the beginning register address where the data will be storedin the other PLC. Only one destination address can be specified forGlobal Data sent by each Bus Controller. If there is more than oneSeries Six and/or Series Five PLC on the bus, they must all use thesame register address for Global Data received from this Bus Controller.For information about selecting and entering a register address for oneof these PLCs, refer to the Genius I/O System and CommunicationsUser's Manual, GEK-90486-1.GFK-2017 Chapter 3 Bus Controller Configuration 3-5
