Explanation: Local setpoint input
A value at "LocalSetpointInput" is only adopted if "Local" = TRUE. If this con-
dition is met, how a pending setpoint is processed depends on whether it is a
hardware or software input. The type of input is decided by the "Continu-
ousEnterFunct" parameter:
• ContinuousEnterFunct = FALSE
Hardware input
A setpoint at "LocalSetpointInput" is only read in when a signal change
0 → 1 is detected at "EnterInput". The setpoint entered locally is output via
the "SetpointOutput" output and transferred to the partner.
A further setpoint is then only read in again by the block when a 0 signal
was detected at "EnterInput" for at least one OB1 cycle.
•
ContinuousEnterFunct = TRUE
Software input
A setpoint at "LocalSetpointInput" is read in continuously and checked for
changes. The change check is achieved by comparison with the last valid
setpoint; in other words, the value stored as the returned setpoint. With
each change, the setpoint is output via the output set at "SetpointOutput"
and transferred to the partner.
With software input a new setpoint can be entered in every OB1 cycle.
With hardware input an empty cycle must be detected before a new
setpoint can be read in by the block.
If you do not require the parameter, simply leave it open.

Explanation: Setpoint output word.

put" is output at the "SetpointOutput" output.
