Hi,
I need to develop a simple website to display some values that are inputted to a PLC connected to a hardware Gateway( HMS AnyBus AB7007) already installed that converts RS485 Modbus to Ethernet Modbus TCP/IP. I am developing my code using .Net (C Sharp)
As I am quite a novice in PLC interfacing, is there a component, AcitiveX control or dll etc (low cost or preferably free:) ) that I can use to communicate with this gateway and get the required values to display on my webpage. I am not aware if a webservice on this gateway already exists.
Any help is sincerely appreciated!
