Beckfoff TwinCAT PLC BC9050 communication?

[hulinning2 0]

Hi, I am new to Beckhoff TwinCAT PLC and I use BC9050 in my project and TwinCAT ADS .NET library to communicate with PLC device. I would like to know if BC9050 can send an event to my Windows application developed with TwinCAT ADS .NET. Currently, my Windows application needs to poll for every input signal on the devices. I know if I use TwinCAT IO instead of TwinCAT PLC then I can use a function call TcAdsClient.AddDeviceNotification to receive signal events from the IO devices. However, the BC9050 cannot support this function call. Thanks
