> This version implements the subscription to PLC Items under the philosophy "Don't call me, I'll call you".
> The requested items are sent periodically by the PLC to the driver. The driver collects the data and sends it to the client.
> This solution is ideal for systems that need rapid data updating and low resource consumption.
> Currently only S7-300 and S7-400.
> S7-1500 the next revision.
