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)
