Corrected from:
OPC tunnel V3.3.2
Behaviour of the new version?
Even under Windows 7 64bits, the OPC tunnel can use a connected controller to establish a connection to a node connected to the fieldbus interface of the controller.
What happens?
It is not possible to establish a connection by the controller via the OPC tunnel to a node connected to the fieldbus interface of the controller.
Example:
The EASY Starter is not able to establish communication via the OPC tunnel of the controller 3200 C to a 9400 HighLine which is connected to the controller 3200 C via CAN.
When does the problem occur?
The response described above may occur if the OPC tunnel is installed on a Windows 7 64-bit PC (depending on the selected safety settings of the operating system).
Which products are affected?
OPC tunnel from V3.1
Diagnostics options?
None
Short-term measures/recommendations?
None
Evaluation:
If the OPC tunnel is installed under Windows 7 64bits, it may happen that it is not possible to establish a connection by a connected controller.
