Timeout Issues When S7 Points Are Exposed by the OPC Server
Message / Issue | Situation | Do the following... |
Timeout issues in S7 devices whose data is exposed using the Desigo CC OPC DA server. | A project includes S7 devices whose points are exposed by the Desigo CC OPC DA server. When a third-party OPC client connects to the Desigo CC OPC DA server, the values of S7 points are not correctly displayed. Also, the log files record timeout errors. |
NOTE: The default value of DeviceType is PX. If DeviceType is empty, invalid, or the [DeviceToSupport] tag is not present, the behavior will always be the one expected for PX. |
