I have been trying to send a message to a scada system using a cp340. the message shape is in bytes the form : port,type,system,subsystem,11 data bytes,count.the data byte represent an ascii code. I have tried to send this message like in the example provided by siemens but it does not work. my message only comes out as gibberish on a data analyzer.I am using the same CP to send a message different to this one using the same method and it works.
