| The following is an example of how to
configure redundant IOServers to the same PLC.
Project must have the following
configuration:
| Citect1:

Be sure to have extended forms on in the Project Editor to
configure the StartUp Mode of each IODevice. This configuration
makes the IOServer, Alarm, Report, and Trend Servers all
redundant.
