Hi everyone,
First I would like to thank you, this forum is very helpfull, I'm glad to become a member.
I'm trying to make a Driver using the DF1 protocol, in order to ba able to communicate with Allen Bradley PlC (SlC500, Micrologix 1000).I'm developing under Visual Basic.Net using RS232 communication.
I'm currently reading the DF1 protocol, but I can't resolve some problems. I can create handle to the COM Port, but I can't communicate with the PLC, and I didn't find anywhere in the protocol what do I have to do to start communication.
If someone knows something that can help me, that would be great !
Thanks !!
Nicolas.
