Linking to an equipment module in DeltaV Operate

The A_COMMAND parameter is an interface to the named set associated with the equipment module. In the example, A_COMMAND is associated with the totalizer named set. To enable an operator to specify a named state for the TOTALIZER equipment module on a picture, you create a datalink on the picture to TOTALIZER's A_COMMAND parameter (specifying the ASCII field, A_CV). This link enables a user to select any named state: totalize_fast, totalize_accurate, and reset.
