Configuring a Secondary Redundant PLC

This section describes the steps for configuration of a Secondary PLC. The programmer for Logicmaster 90-70 software must be connected to the Secondary PLC in order to configure the Secondary PLC. There are several ways to configure a Secondary PLC in a Hot Standby CPU Redundancy system. One method is shown here.

Create a new folder for the Secondary PLC system. Copy the data from the Primary PLC system to the Secondary PLC system folder. This process will save time since you will not need to re-enter the configuration parameters that are common to the two redundancy systems.

This example shows how to change the Primary PLC redundancy configuration described on the previous pages to a Secondary PLC redundancy.

Enter the I/O Configuration software by pressing the I/O softkey (F1). The configuration for rack 0 appears as shown below (note that this is the configuration that you had selected for the Primary PLC)
