[scited-blog]

I wrote a simple program for Scene2. I implemented states using a word in memory to hold the state id and then compare and movp to change between the states. I also added timers to each state to generate a fault if the state does not complete without the expected time specified. I did not create any logic to handle the error so for now the PLC just flags and continues. Next I would add the routines for error handling and also the EMO logic. I will leave it for now and continue to the next simulation.
