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
