Hello. I really need help with this. It is part of my thesis
I have a Hydraforce ECU0710 controller. This equipment only accepts CAN communication. I am using CodeSys V2.3 to programm the equipment. This part is working perfectly. What i need to do now is to connect this CodeSys with another software or to share information with other software, parallely.To do that i have two ideas:
I can create a TXT file from the second software with the information i want to send; and then, make Codesys to read this TXT file., so i can use this information the code. The problem with this solution is that i do not know how to make codesys to read file from the windows directory. I mean, i want CodeSys to read a TXT file from a local path, and get information from this file.
I can use OPC server. I was reading that it is possible to use OPC but i have not found any proper documentation to understand.
Please, can someone help me with another idea or with the ones i came up with?
let me know....
OPC is obviously the cleanest way. I would not go with the file solution, as it sounds too hacky to me.
Another possibility might be network variables. There are a few free netvar implementations available.
