Footer
Some of the predefined faceplates have a footer to show current locks, statuses, warnings and alarms for their P&ID element. A set of the footer elements depends on the type of DataAssembly which MTP PLC Library FB presents.
This is an example of a faceplate with the footer containing only the Status element (in “NORMAL” state):
This is an example of a faceplate with the footer containing the Active Lock element (in state “NONE”) and the Status element (in “NORMAL” state):
For faceplates which have the footer, the WQC message element also appears in addition to other messages if the WQC status has an active value (see table). An example of an active WQC message element:
