A value at LocalSetpointInput is only adopted if the Local input parameter is
set to TRUE. If this condition is met, how a pending setpoint is processed
depends on whether it is a hardware or software input. The user specifies
the type of input with the ContinuousEnterFunct parameter:
• ContinuousEnterFunct = FALSE (= hardware input)
The setpoint at LocalSetpointInput is only read in when a signal change
from 0 to 1 is detected at EnterInput. The setpoint entered locally is
output over the output set with SetpointOutput and transferred to the
partner for display. A further setpoint is then only read in by the FB when
a 0 signal was detected at EnterInput for at least one OB1 cycle.
• ContinuousEnterFunct = TRUE (= software input)
The setpoint at LocalSetpointInput is read in continuously and checked
for changes. The change evaluation is implemented by comparing the
current value with the last valid setpoint; in other words, the value stored
as the returned setpoint. Every time there is a change, the setpoint is
passed immediately to the output specified by SetpointOutput and sent to
the partner for display.
While for hardware input an empty cycle must be detected before a new
setpoint can be read by the block, for software input a new setpoint can
be entered in every OB1 cycle.
If you do not require the parameter, simply leave it open.
