Archiving Of Images And Diagnostic Information On A Pc - Siemens SIMATIC MV500 Operating Instructions Manual

Adding program change
Specify the number of the required program in memory byte MB200. The program change
runs automatically. The correct order of the commands is adhered to. The FB changes to the
program specified in the "PARAM1" parameter.
Avoiding undefined plant states
To avoid undefined plant states, you should only change programs when the plant is in
manual mode or is not in operation.
Startup OB OB100
In OB100, you set the RESET input of FB 79 to initialize the FB. This input is reset by the FB 79
call.
Bits of the control and status bytes used
You must edit the following control and status bytes in addition to the FB 79 call in your
program:

Archiving of images and diagnostic information on a PC

You can find the program described in this section, "MMI Diagnostic Recorder", on the web
pages of Siemens Online Product Support
(https://support.industry.siemens.com/cs/ww/en/ps/15147/ae).
The MMI Diagnostic Recorder supports you with the diagnostics and maintenance of your
application. Among other things, it saves diagnostic data records as CSV files and saves all
images taken by the reader and corresponding to the set filters (e.g. "only bad reads", "match
errors" or "only successful reads") on an external PC. Please note that this function can affect
the network load if you have set a fast acquisition interval. If the image packets cannot be
sent on time, there is a buffer of up to 50 images. If this buffer is full, the corresponding
images are discarded.
