The plus sign indicated in the indication is a confirmation of the command execution:
The command output has a positive result, as expected. A minus sign means a neg-
ative, i.e. an unexpected result; the command was rejected. Figure 2-126 shows an
example in the operational indications command and feedback of a positively run
switching action of the circuit breaker.
The check of interlocking can be programmed separately for all switching devices and
tags that were set with a tagging command. Other internal commands such as over-
riding or abort are not tested, i.e. are executed independently of the interlockings.

The standard interlocking includes the checks for each switchgear which were set
during the configuration of inputs and outputs, see SIPROTEC 4 System Description.
An overview for processing the interlocking conditions in the relay is shown in Figure
