Operation principle

The PSTO input selects the operator place (LOCAL, REMOTE or ALL). One of the eight
outputs is activated based on the command sent from the operator place selected. The
settings Latchedx and tPulsex (where x is the respective output) will determine if the
signal will be pulsed (and how long the pulse is) or latched (steady). BLOCK will block
the operation of the function – in case a command is sent, no output will be activated.
PSTO is the universal operator place selector for all control functions.
Although, PSTO can be configured to use LOCAL or ALL operator
places only, REMOTE operator place is used in SPC8GGIO function.
