The AnalogControlFunctionType describes an analogue control function (using analogue values). In addition to the LADS BaseControlFunctionType, the ParameterSet has been made Mandatory. More specialized analogue control functions can be derived from this ObjectType. The AnalogControlFunctionType is formally defined in Table 95.

The StartWithTargetValue Method starts a Function on the LADS Device with the target value as an argument.
The signature of this Method is specified below. Table 91 and Note: The optional TargetValue can be also empty. In this case it should be handled as it not exiting.Note: The optional TargetValue can be also empty. In this case it should be handled as it not exiting.
Table 92 specify the Arguments and AddressSpace representation, respectively.
