How to deal with concurrent reading of tags #40

I looked into this a few years back and I think I stumbled over the same problem as you that some COM calls with go-ole are not supported, at least back then. I haven't kept track of it because the current solution works well with our OPC DA legacy system. Let me know if you find out more. It would be a nice feature. |

Now for one opc server, we only can read the tags one by one, If one of the tags cannot be read, the delay will increase.
