| With acyclic process value archiving, a process value is saved when it changes or depending on an event in the archive database. | |
| The process value is archived: | |
| Either with every change of a process value |
Either with every change of a process value
Or in case of event-driven acquisition – by means of a tag (binary tag: change of the value (0 / 1), analog tag: rising / falling edge). – By means of a script if the return value changes in comparison to the last call of the function. The value "TRUE" must be returned at the first script call.
Each process tag in WinCC (B) corresponds to a certain process value in the memory of one of the connected automation systems (A). In case of change: Every change of the process value is read out from the memory of the connected automation system (2). If you only want to archive a value when it changes to "1" or "TRUE", you must configure the "signal change 0 -> 1" for archiving of a binary tag. Event-driven: The process value is archived if the tag assumes the value "1" and then the value "0" once again for a configured event or the script receives the return value "TRUE" and then the return value "FALSE" once again (1). The Runtime component of the archive system (C) processes the process value. The actual value of the process value is then written to the archive database (D) (3). Acyclic process value archiving ends when Runtime is terminated.
Process-controlled process value archiving is used for archiving several process tags or rapidly changing process values. The process values are written to a process-controlled tag, which s decoded by the archive system. The process values obtained in this way are then stored in the archive database.
Each process tag in WinCC (B) corresponds to a certain process value in the memory of one of the connected automation systems (A). At the start of runtime, the process values of the selected process tags are read out (1) and written to the configured process-controlled tag as binary data. The runtime component of the archive system (C) processes the process-controlled tag: ● The format DLL (2) is part of the archive system and decodes the binary data of the processcontrolled tag. The decoded process values are then written to the archive database (D)
