Know Issues on Windows 7

The default behavior is to allow the operating system to allocate the local endpoint ip port number for the Ethernet connection.  Some GE 9030/9070 PLC's have a firmware bug that refuses connections from endpoints that have a high value port number.  This problem occurs on Windows 7 and Windows 7(64-bit) machines.  To work around this 9030/9070 bug, you can specify and optional source port.
Controller.IPAddress = ipaddress<:portnum>

Example

Controller.IPAddress = "192.168.1.45:2235"

The port number 2235 will be bound to the local endpoint.  The user is responsible for port number allocation and management.  Please check with your IT department.

VB
Try

    ' * check for errors
    If MyPLC.ErrorCode = ResultCode.E_SUCCESS Then
       Console.WriteLine("Connect Success")
