To help avoid creating an unintentional loop caused by connection to the service port, select the Automatic blocking of service port on Standby CPU check box that appears in the ServicePort tab of the configuration dialog.
This check box is available with Ecostruxure Control Expert software.
NOTE: Unity Pro is the former name of Control Expert for version 13.1 or earlier.
To configure, select the ServicePort tab.
Select the Automatic blocking of service port on Standby CPU check box so that the service port of the standby CPU is automatically blocked.
De-select the check box so that the service port is not automatically blocked.
The check box is deselected (unblocked) by default.
NOTE: These features are implemented in a Hot Standby system using a CPU with firmware version 2.7 or later and a BMENOC0301.4 or later module.
