A server (3) without a process driver connection deals solely with message and process value archiving. The server (3) collects the data from all other servers (2) through server-server communication and distributes it to the clients (1):
Process values are data stored in the memory of one of the connected automation systems. Process values represent the status of a plant or parts thereof, for example, temperatures, fill levels or states (e.g. motor off). To work with the process values, you define tags in WinCC. The link between WinCC and the automation systems is provided by process tags, which correspond to a certain process value in the memory of an automation system. The value of a process tag is obtained by reading out the process value from the memory of the automation system. On the other hand, a process value can also be written back to the memory of the automation system.
External tags are used to acquire process values in WinCC. They access a memory address in the connected automation system. External tags are therefore referred to as process tags. Internal tags do not have a process link and only carry values within WinCC. External and internal tags can be stored in archive tags in the process value archive. Note As the primary task of process value archiving is the archiving of external tag values, this documentation refers only to process tags.
Process values are stored in archive tags in the process value archive. The system distinguishes between the following types of archive tags: ● Analog archive tags store numerical process values, e.g. the fill level of a tank. ● Binary archive tags store binary process values, e.g. whether a motor is switched on or off. ● Process-controlled tags store process values that have been sent to the archive system as frames, e.g. process values in a series of measurements. Archived process values can be compressed. This compression is achieved through the application of mathematical functions (e.g. averaging). Compressed process values of this type are stored in compressed tags in a compressed archive.
| In the automation system the process values are written to a binary file, and are sent as a frame to WinCC where they are stored in a raw data tag. | |
| If you want the acquired process values belonging to a raw data tag to be archived, you need to configure a process-controlled tag in the process value archive. | |
| To enable the archive system to process the frame in the process-controlled tag, select a format DLL. The format DLL is supplied with the automation system that you are using and dismantles the frame (e.g. to ascertain the process values). |
Process-controlled tags (frame tags) are needed for the acquisition of quickly changing process values, or if you want to combine several measuring points from one system. Note Process-controlled tags are of the "raw data type" in WinCC and are therefore also referred to a "raw data tags".
