15.3 Notes on visualisation using »VisiWinNET®«
Problem description:
For visualisation purposes a VWGET timer (1 second) is used to read a variable via the CAN
bus (SDO) using the OPC server. If no nodes are connected and no information is returned,
a time-out is generated. Waiting for the time-out causes the page-turning function of the
visualisation program to slow down.
Solution:
 The visualisation program can be operated again if the following lines of the time-out
are changed in the PosStart.txt file:
 Otherwise VWSET and VWGET must not be used for visualisation purposes.
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\CAN2Bus1]
"SDOTimeout"=dword:0xc8
"Timeout"=dword:0xc8
