Typical times required for the execution of the GMR system software for either the CPU788 or CPU789 are shown below. In this example, there are six bus controllers in each PLC. With Table sizes of: With Table sizes of: Voted %I = 64 Voted %I = 256 Voted %AI = 64 Voted %AI = 256 Logical %Q = 64 Logical %Q = 256 Scan Time Contribution = CPU788/789: 79 ms CPM790: 22 ms Scan Time Contribution = CPU788/789: 88 ms CPM790: 24 ms The scan time contribution for the execution of the GMR system software for your system could be more or less depending on the table sizes you configure. Also this time varies by +/– 10ms for the CPU788 and 789 (+/- 2ms for the CPM790) during single scans when the GMR system software performs diagnostics on the CPU subsystem and subsystems. Typical GMR CPU total scan times range from 22 milliseconds to 300 milliseconds (or higher) depending on configuration, size of the application program and instructions used in the application program. To estimate the total scan time and/or scan time contributions for the other operations that take place during a scan please refer to the Series 90-70 Programmable Controller Reference Manual (GFK-0265) Appendix A: “CPU Performance Data.” That appendix includes worksheets to assist you in estimating scan time for your own system. If you are estimating total scan time using these worksheets, you must add the scan time associated with executing the GMR system software (as noted above) separately. Genius Bus Scan Time The GMR system utilizes Genius as its input and output subsystem. Genius blocks operate on a serial communications network that interfaces to the GMR CPU subsystem through Genius bus controllers. This serial token–passing type of network has its own scan time which is separate and asynchronous from the CPU scan time discussed above. This “Genius bus scan time” is the time required for all devices on a Genius network to communicate on the network one time. The Genius bus scan time can be estimated if all of the devices (and their configurations), to be put on a bus are known. Typical Genius bus scan time range from 5 milliseconds to 60 milliseconds (or higher) depending on the configuration. Please refer to GEK-90486-1, the Genius System and Communications User’s Manual, Chapter 9: “Timing Considerations” for further details on estimating Genius Bus scan times. Response Time If input, output or total input–to–output response time estimates are desired, both the CPU and Genius Bus scan times must be taken into account. Please refer to GEK90486-1, the Genius System and Communications User’s Manual, Chapter 9: “Timing Considerations”, for details on estimating response times.

General Computer Requirements The configuration and programming software used for GMR require an IBM or IBM compatible personal computer. Minimum requirements for running the Logicmaster software are: n An Intel 80386 or higher microprocessor. n A hard disk with at least 4 Megabytes of space available. n At least 2 megabytes of RAM memory (see additional information at right). n MS-DOS Version 5.0 or later. Both monochrome and color monitors are supported. Printer Requirements Use of an optional printer is recommended for program and configuration documentation purposes. Computer Memory Requirements for the Logicmaster 90-70 Software Specific memory requirements for running the Logicmaster 90-70 software depend on its version. n The Release 6.5 version of Logicmaster 90-70 software for GMR requires; o A minimum of 545 K (558,080) bytes of available conventional RAM memory to run. o At least 1024 Memory (LIM EMS 3.2 or higher).
