The Basic Steps of Configuration
1. Complete the GMR configuration. This information is the same for the redundant
PLCs – 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 produces:
A printout of the GMR Configuration. Use it as a reference during subsequent
programming and configuration.
A program block named G_M_R10. This is later added to (imported into) the
application program.
2. Create a Logicmaster configuration for each PLC. The easiest way to do that is to:
A. Create a Folder for PLC A, PLC B, and PLC C.
B. Select to the folder for PLC A. With the GMR configuration printout as a
reference, complete its Logicmaster configuration.
C. Use the Copy Folder feature of the Logicmaster 90 programming software to
copy the configuration of PLC A to the folders for PLC B and PLC C. To do this:
(1) From the Logicmaster configuration software, return to the Logicmaster
programming software. Select the Program Folder functions.
