I currently have a Precision Digital Nova PD500 series controller connected to a computer through a RS485 to USB converter. It came with software to read the PV, SP etc. on the computer and I am able to connect to the controller through this software and read this data. However I want to use the MatrikonOPC Server for Modbus to transfer this data to Siemens WinnCC HMI software. I created a Serial Port Node with the same address as my controller and the same communication data (parity, baud rate, etc.). However when I attempt to read data from the controller using MatrikonOPC explorer, the @Connected tag, shows that I am not connected to the COM port. I'm not sure what I need to do in order to receive data from the controller. If anyone knows, that would be great.

Thanks,

Matt
