every signal have default limits (0 to 100) but values are higher than limits
In this case, you get Bad quality status?
If you need to use values with bad status as good values, I can provide the source code of the OPC DA driver, so you can change it as needed.
The above description is correct.
Sorry if it is studi question but how to modifiy the driver ?
1. Change the driver by yourself using the source code.
2. Sponsor the update, and we would implement the required feature.Any source code somewhere ?
Driver’s source
See DrvDbImport projects. For example, DrvDsOpcUaServer supports long strings.Bad quality status is received only by Rapid SCADA driver or also by other OPC clients, like Matrikon OPC Explorer?
Hello,
It may depend on the communication protocol. Could you provide screenshots of the Communication line settings?
Hi,
Thank you for the screenshot.
In Rapid SCADA 6 channels of the string type may contain more then 8 characters.
However, the DB import driver currently does not support long strings. The driver needs an update to implement the required feature.After build, the executable and other files should be correctly copied to the runtime location as the installer does. Services must be registered in the system. Then they can be started.
Hi,
My be it’s better to create new components inheriting them from the existing, because in this case you have more freedom to add new features.
Hi,
The instruction is here. In Rapid SCADA 6 the Formulas table was renamed to Scripts. You should copy from line 21 to 205.
The formulas also should work on the 6th version.I think, it’s better to develop new components using the existing components as base classes, or as examples.
