Description of the "Upload PLC data" function
The diagnostic action "Upload PLC data" permits some or all of the PLC data
blocks to be uploaded the ePS server on a trigger event, using a control monitor.
Notice
The PLC data blocks are available on the ePS server without a specific format.
Precisely one contiguous range of the same data block can be selected for
uploading for each control monitor.
For the purpose of displaying the DB content, the data from the ePS Network
Services menu (machine events) must be exported and saved. A hexadecimal
editor or byte-by-byte conversion in Excel is recommended for visualization pur-
poses.
In the case of data block content that changes dynamically from the point directly
after the trigger event up to the point when transfer to the ePS server is complete,
due to the limited bandwidth of the communication channel to the PLC, it cannot
be guaranteed that the statuses are from a single cycle.
