FB_MTP_LockView4

The function block FB_MTP_LockView4 is an object for visualizing a basic logical operation AND/OR with four inputs. This is made available via OPC UA.

Each input can be enabled *En, inverted *Inv and described with a text *Txt. Each input also contains a quality code *QC. It describes the conditions under which the value of the interface was recorded and how trustworthy this value is.

The inputs can be evaluated as AND-logic (Logic = TRUE) or as OR-logic (Logic = FALSE). The linking result from the inputs is output at Out . Only enabled inputs are taken into account for this. The result of the QC inputs is output at OutQC.
