OK, I am trying some things with the SDK samples for VB. I have compiled the sample that monitors ActiveHomeObj.RecvAction and writes the received information to the console screen. If I send something like "sendplc A3 dim 50", the ActiveHomeObj.RecvAction displays exactly that. However, if I send "sendplc A3 ExtCode 31 3F" the console shows nothing. Can the SDK receive extended codes? I want to try some things with extended codes using the SDK, but I can't seem to get it to receive them.
