MVP 2021 Joe Tauser Posted May 31, 2012 MVP 2021 Report Share Posted May 31, 2012 I've got a programming methodology question. We have a project where a single V570 is connected to all the I/O for the system and runs the process. The problem comes in where we have two additional V570's on a CANbus network using UniCAN that need to duplicate the screens and allow the user to change many parameters on any screen. I am broadcasting the data via timers from each screen to the others, but as you can image we are getting into a data race and the logic is starting to look like a big rat's nest trying to keep the data updated based on who entered what last. I am doing this wrong. I can feel it. Can anyone suggest a structure that will bring order and serenity to a multiple-master system? How do you tokenize an n-order CANbus network? Joe T.
