Hello,
I really need help with this, I have a project where I will read some values from a process with Arduino and we need to send it to a SCADA application in Indusoft and we will connect the Arduino to a Switch and from the Switch. I will go to the network and for Ethernet communication I will read the values, we wanted to use an RS-232 to Ethernet converter but we saw that it was cheaper to use an Ethernet module and I chose the ENC28J60, but I am looking for information about the EtherCard library, and although they are illustrative not I find the description of the functions or methods that the library has, I don't know if someone can help me.
My goal is basically the following, to make a program in Arduino that reads the value through an analog input (I have solved that problem) and that this value is sent by Arduino through the Ethernet module so that it can be read from the SCADA by some Ethernet controller, what I want to do, is it possible with the module I buy? I saw that they use it as a server and I don't know if I can use the Ethernet module that I buy for the purpose I want or not. Or do you recommend using the ethernet shield, the one that connects to the entire Arduino board and has a built-in microSD reader, or do you recommend using the RS-232 converter that I thought at first?
If someone could help me I would be very grateful please
