Setpoint value type
|
Explanation
|
---|---|
Remote setpoint
(SP_RSP = 1)
|
The Setpoint comes from a block external calculation using the input RSP (remote setpoint). The input value RSP leads to the SP output.
|
Local setpoint
(SP_RSP = 0)
|
The setpoint must be modified directly by the user (Local setpoint). In this operating mode the output SP is not entered using the function block, the variable attached to the SP is modified by the user.

CAL SP_SEL_Instance (RSP:=RemoteSetPoint, SP_RSP:=TypeOfSetPoint, PARA:=Parameters, PV:=ControlledVariable, MA_I:=OperatingMode, SP:=SetPoint, LSP_MEM=>LocalSetPointMemory, STATUS=>StatusWord)
SP_SEL_Instance (RSP:=RemoteSetPoint, SP_RSP:=TypeOfSetPoint, PARA:=Parameters, PV:=ControlledVariable, MA_I:=OperatingMode, SP:=SetPoint, LSP_MEM=>LocalSetPointMemory, STATUS=>StatusWord) ;
