in ascending order (if the present activated output is 3 – for example and one
operates the UP input, then the output 4 will be activated). When a signal is
received on the DOWN input, the block will activate the output next to the present
activated output, in descending order (if the present activated output is 3 – for
example and one operates the DOWN input, then the output 2 will be activated).
Depending on the output settings the output signals can be steady or pulsed. In case
of steady signals, in case of UP or DOWN operation, the previously active output
will be deactivated. Also, depending on the settings one can have a time delay
between the UP or DOWN activation signal positive front and the output activation.
Besides the inputs visible in the application configuration in the Application
Configuration tool, there are other possibilities that will allow an user to set the
desired position directly (without activating the intermediate positions), either
locally or remotely, using a "select before execute" dialog. One can block the
function operation, by activating the BLOCK input. In this case, the present
position will be kept and further operation will be blocked. The operator place
(local or remote) is specified through the PSTO input. If any operation is allowed
the signal INTONE from the Fixed signal function block can be connected.
SLGGIO function block has also an integer value output, that generates the actual
position number. The positions and the block names are fully settable by the user.
These names will appear in the menu, so the user can see the position names
instead of a number.
