If a command with multiple outputs is configured, all binary outputs required in the
matrix for the configuration are automatically defined. If one of these outputs is de-
configured, all other binary outputs associated with the command will be automatically
de-configured.
Please pay attention to the comments and switching examples in Section 5.2.1,
particularly the fixed defined sequence of relay assignments (TRIP before CLOSE).
When configuring commands (C_), the context menu is dependent on the type of
command. In some cases, the selection latched/unlatched is not available. Instead,
the alternatives are ; (configured), B (not configured), and ) (busy flag). The latter
means, independent of the switching direction, an indication is issued during each
operation of the switching device.
For double commands with a common output, a fourth alternative & (Common contact)
appears. Using this, the binary output may be defined as the common output (common
contact). When this is the case, several double commands with common contacts may
be assigned to the same common output (common contact), thus saving binary
outputs. This assumes the signals at the common outputs have the same potential.
Using the 2EMHFW 3URSHUWLHV dialogue window, additional properties for
commands issued to the switching device may be defined. Thus, the operating mode
(pulse or latched output of a switching command), the seal-in time for pulse
commands, the output delay of the command, and feedback monitoring may be set
(see Figure 5-29). The output delay is relevant for equipment which removes an
indication before the switching is completed.
