Create the BLENDER_OUTLET equipment module class

Earlier we configured a control module called NC_VALVE. (We started from the VLVNC-11 control module template and added a valve setpoint, a deadtime block, and a PV output parameter.) Now we will add two copies of this control module class to the equipment module class to represent the two outlet valves. The resulting module blocks will be named PRODUCT_VLV and WASTE_VLV. We will also add the 2STATE_MTR control module class to be used as the OUT_PUMP. The 2STATE_MTR control module class was imported as part of the Startup.fhx file.

  1. First, create an equipment module class category of StateDriven under Equipment Module Classes in the Advanced Definitions section of the Library.
  2. Right-click StateDriven, and then select New Equipment Module Class.
  3. On the New Dialog, enter BLENDER_OUTLET as theObject name.
  4. Select Create New, and then select State-driven as the algorithm type.
  5. Browse for the named set outlet_state.
  6. Click OK to create the equipment module class.
  7. Drag the NC_VALVE control module class to BLENDER_OUTLET. Rename the resulting module block (NC_VALVE_1) to PRODUCT_VLV.
  8. Drag the NC_VALVE control module class to BLENDER_OUTLET and rename the new module block WASTE_VLV. 
  9. Drag the 2STATE_MTR control module class to BLENDER_OUTLET and rename the new module block OUT_PUMP.
  10. Open the Properties dialog for BLENDER_OUTLET. On the Displays tab, browse for and select Process as the primary control display.
