Instructions on how to use the PKS auxsummer function block.

The AUXSUMMER (Auxiliary Summer) block allows you to configure up to ten separate inputs in order to calculate a process variable (PV) value, which can be scaled and offset. Status information is provided for each input, as well as for the PV value itself. Through configuration, you can define a scale factor, an offset value, and a description for each input. You can also choose to disable an input; by default, all inputs are enabled. Graphically, it is represented as follows: PV = CPV {((C P) + D ) + ... ((C P )+ D )} + DPV, where CPV represents the overall scale factor for the PV, DPV represents the overall offset for the PV, C represents the scale factor for input ‘i’, D represents the offset for input ‘i’, P represents the value of input ‘i’, and i ranges from 1 to 10. The AUXSUMMER block retrieves values from other function blocks and determines their status in each execution cycle of the Control Module. It evaluates up to ten inputs and determines their status, deriving values for the PV and its status based on these inputs along with the configuration settings for the overall PV scale factor (CPV) and overall PV offset factor (DPV). You can also choose to disable an input (using PENABLE) and define a substitute value (PSUB) for that disabled input
