Hello,
It is possible that your code is fine, but that your hardware configuration is incorrect. I recommend that you download the Server Explorer application from our website. This application will allow you to monitor all of the channels of the OPC server on your machine which will include the channels of your FP-AO-210. This will allow you to monitor the values of each channel and determine if your hardware configuration is correct. Also, if you have not yet upgraded to the latest FP driver, you may wanted to consider upgrading. Here are links to download the Server Explorer and the latest FieldPoint driver.
