FWRIT Question

6 posts in this topic

I am fairly new to programming and I used an fwrit function on CS1G plc with #3800 and I am only collecting 200 blocks of data and then it stops. I have watched and after it stops collecting data the busy signal on my plc stops flashing. What can I look at to fix this issue?
