SLGGIO can be activated both from the local HMI and from external sources
(switches), via the IED binary inputs. It also allows the operation from remote (like the
station computer). SWPOSN is an integer value output, giving the actual output
number. Since the number of positions of the switch can be established by settings (see
below), one must be careful in coordinating the settings with the configuration (if one
sets the number of positions to x in settings – for example, there will be only the first
x outputs available from the block in the configuration). Also the frequency of the (UP
or DOWN) pulses should be lower than the setting tPulse.
The operation from local HMI is from select or indication buttons (32 positions).
Typical applications are: Select operating modes for e.g. Auto reclose, Energizing
check, Earth-fault protection (IN,UN). The output integer can be connected to an
Integer to Binary function block to give the position as a boolean for use in the
configuration.
10.6.3 Setting guidelines
The following settings are available for the Logic rotating switch for function
selection and LHMI presentation (SLGGIO) function:
Operation: Sets the operation of the function On or Off.
NrPos: Sets the number of positions in the switch (max. 32). This setting influence the
behavior of the switch when changes from the last to the first position.
OutType: Steady or Pulsed.
tPulse: In case of a pulsed output, it gives the length of the pulse (in seconds).
tDelay: The delay between the UP or DOWN activation signal positive front and the
output activation.
StopAtExtremes: Sets the behavior of the switch at the end positions – if set to
Disabled, when pressing UP while on first position, the switch will jump to the last
position; when pressing DOWN at the last position, the switch will jump to the first
position; when set to Enabled, no jump will be allowed.
