Recently I am having problems with a connection between Opto22 and SQL by OptoDataLink.
I was able to create multiple connections to SQL and it works great. But I have problems with EB2.
The error I get is in Spanish, sorry “Referencia a objeto no establecida como instancia de un objeto” (“Object reference not set to an instance of an object”)
I tried to configure a single TAG with a single table but the error is the same.
Can anyone help?
