The Basic Steps of Configuration and Programming
1. Use the GMR configuration software to complete the GMR configuration. There is
only one GMR configuration needed for the system. GMR configuration sets up the
parameters that will be used by the system, including reference addresses. The GMR
configuration software produces:
A printout of the GMR Configuration.
A program block named G_M_R10. This is later added to the application program.
2. Using the LM90 configuration software, create a Logicmaster configuration for
each PLC. The easiest way to do that is to:
A. Create a Program Folder for PLC A. With the GMR configuration printout as a
reference, complete its Logicmaster configuration.
B. Use the Copy Folder feature of the Logicmaster 90 programming software to
copy the configuration of PLC A to additional folders for PLC B and PLC C.
C. Edit the configurations for PLC B and PLC C as necessary.
3. Using a Hand-held Monitor, complete the Genius block configuration. Genius block
configuration sets up the operating characteristics of each block in the GMR system.
4. Using the Logicmaster 90 programming software, create the application program.
While there can be up to three PLCs in a GMR system, each of which has a slightly
different configuration, there is normally only one application program.
A. Using Logicmaster 90, copy the folder named GMRxxyy (for example,
GMR0101) from the GMR software diskette to a program folder with your
application program name (such as GMRPROG).
B. Using Logicmaster 90, add program block G_M_R10 (created with the
configuration utility) to the application program folder.
C. Create or add the application program logic in this folder.
5. After completing the application program and the configuration(s), store them to
the PLCs. As explained above, all redundant PLCs in the GMR system normally use
the same application program, but different configurations:
PLC A
PLC B PLC C
Program: GMRPROG
Configuration: CONFIGA
Program: GMRPROG
Configuration: CONFIGB
Program: GMRPROG
Configuration: CONFIGC
Supplying the configuration and program as separate files, as shown, makes it easier
to perform program updates in the future.
The GMR Configuration Software allows the system to be set up for online program
changes. Online changes are intended for system debug and commissioning.
