why function blocks ?
YASENSE Excel enables you to easily use an Excel model in production, without the need to program the calculations in a PLC.
However, it can be useful to be able to manage some aspects of your model from the PLC or DCS side. For that purpose we have introduced an optional function block that represents the Yasense Excel Runtime.
Anyone who knows PLC/DCS programming can modify the inputs and outputs of the model and add additional pre- and postprocessing.
In the mind of the PLC/DCS programmer, the YASENSE Excel Runtime is then just another function block. The calculations that are specified in Excel seem to happen inside that function block.
A function block for the Siemens PCS-7 DCS is available as an option.
