Description
To show the desired values the buttons »1x fetch«, for a refresh once,
or »cyclic fetch«, for a permanent online request, are available.
With »Save Configuration« the created mask including all set variables
and their descriptions can be stored in the ACCON-NetLink-PRO
compact.
The refresh rate is set to 0.5 seconds. If several stations use this
function from the TCP/IP side, then there is always only one connection
resource reserved in the ACCON-NetLink-PRO compact. During the
additional data exchange via MPI/PROFIBUS the »Observe Variables«
function has the lowest priority. Thus the refresh rate in the web
interface is dependent from the parallel bus load.
