Using the GMR Configuration Software

The GMR Configuration Software is used to enter data needed by the GMR program software.

HAutotest interval

HCPU type for the system

HI/O limits for the system

Hinitialization data for the system

Hfault actions for the system

Hall GBC (bus controller) groups, with all Genius I/O blocks that will use GMR features

The GMR Configuration Software is not part of the Logicmaster 90 software package. It is a separate utility that operates on an IBM PC or compatible computer. It runs under DOS. Either a keyboard or mouse can be used for making entries.

After all the necessary configuration entries have been made, the data is added to the

GMR system software. The GMR system software is provided as a Logicmaster 90

Program Folder, to which the application program is then added.

To assure matching the entries made with the GMR Configuration Software to corresponding entries made during Logicmaster 90 configuration and Genius block configuration, the GMR configuration data should be printed out and used as a reference.

The GMR software requires that:

Hall PLCs have the same number of bus controllers in the same positions (not includingªnon-GMRº bus controllers).

Hall PLCs are connected to the same ªGMRº Genius busses.

Genius busses used for either I/O or communications that are not common to all PLCs in the system, or that do not use bus addresses as described above must not be included in the GMR configuration.

GMR Configuration Software Revision and Checksum

The system monitors the checksums of both the configuration data and the application program, including the GMR software modules. As part of the GMR configuration, you can select whether to permit online changes. If online changes are permitted, a configuration mismatch will not stop the PLC. If online changes are not permitted, a configuration mismatch will stop the PLC. The table on page 4-3 shows in detail what happens if a configuration mismatch is detected.
