Configuring a Primary Redundant PLC

The steps required for configuring a Primary Redundant PLC are described below. The Primary PLC and the Secondary PLC must be configured separately. An example of the configuration screens for each system is provided on the following pages. The programmer must be connected to the CPU in the Primary PLC to configure the Primary PLC and then moved to the CPU in the Secondary PLC to configure the Secondary PLC. First, the Primary PLC will be configured.

While in the Configuration Software main menu, select I/O (F1). The default configuration for the I/O Configuration Rack screen is displayed.

Position the cursor on rack 0, slot 1 and press the zoom softkey (F10) to zoom into the CPU module currently configured in slot 1. Press the cpu softkey (F1) to have a catalog list of the available CPU modules displayed. The currently selected CPU is highlighted in reverse video.
