n Fault actions for the system n All GBC (bus controller) groups, with all Genius blocks that will use GMR features n addresses and other features of GMR block groups: n For each circuit, synchronous or asynchronous Autotest, at intervals ranging from 1 minute to more than 45 days. n How long inputs may be discrepant before the CPU places a message in the Fault Table and sets a fault contact. The range is 1 second to 18 hours. n Starting addresses and lengths for any memory areas to which data can be written to through a CMM, PCM, or Ethernet Communications Module. GFT-177A Section 5 Configuring & Programming a GMR System 5-3 5 PLC System Configuration The overall PLC system configuration is completed using the Logicmaster 90-70 software, which also runs on a personal computer. Modules are quickly selected from lists by function key. It is possible to completely configure the system offline with no PLC hardware present. Typical Module Type Selection Menu After selecting a module, it appears on a screen that represents that rack being configured. Example Rack Definition Screen Zooming into a slot shows a detailed description of the module configuration: Detail Screen for a Module Automatic Configuration Documentation The configuration information for the GMR system can be sent to a printer so a hard copy of the current configuration documentation is easily prepared. The information may also be exported to documentation software under the DOS or Windows operating systems. Configuration Genius blocks and Field Control Bus Interface Units in the system are configured separately to assign parameters such as address, type, diagnostics, operation, communication, and mode settings. 5-4 Genius® Modular Redundancy Flexible Triple Modular Redundant (TMR) GFT-177A System Technical Product Overview – February 1998 5 Programming The Logicmaster 90-70 software is also used to create the Relay Ladder Logic GMR application program. An example screen of logic during edit is shown below. The top of the Logicmaster screen always shows the current assignments of the function keys, which are used to select program functions. For example, on the program editing screen illustrated below, the second row shows Contacts. Each Contact can be selected with one key press. The status information at the bottom of the screen can be turned off for even more program display area. Example Relay Logic with Contacts The Series 90-70 PLC provides a large and extremely versatile set of coils, contacts, relational functions, logical functions, and many advanced functions for use in the application program. They are described in the table that begins on page 5-10. The same application program is used for each GMR PLC, eliminating the need for individual logic programs and simplifying user programming. Application programming assistance is available from your GE Fanuc sales office, or GE Fanuc’s 24 hour support hotline @ 804 978–5747. Through Logicmaster 90, the GMR CPU supports structured programming techniques. Program logic can be separated by functionality, equipment areas, or other logical sections. The GMR programmer may write an efficient program with reduced effort using structured programming tools, which include: n Function Blocks for complex functions n Custom Parameterized Subroutine Blocks n Program Blocks Function Blocks for Complex Functions Function blocks simplify programming complex functions in the GMR application program using Relay Ladder Logic. Multiple parameters are easily included in a function block, in a clearly-understood fashion.
