7 – Configuring Controllers
100 R400
For some types of controllers, it is necessary to disable and then re-enable the
channel or controller in order to re-establish communications after the problem
has been rectified. For details of these procedures, see “Enabling and Disabling
Channels and Controllers” on page 109.
Communications Redundancy
With some types of controllers, PlantScape provides the option of defining
redundant communications links to provide a safety net in the event of
communications link failures.
To install redundant communications links you need to:
1 Define the redundant channels in the appropriate Quick Builder property
tab for each controller.
2 On the Channel Configuration Summary, click Show Redundant Link
Status.
