FIFO buffer

[Tonko 0]

I am working on a CJ1M, and I need to develop a FIFO buffer in a file, using de CF. I know there are instructions to manage FIFO lists in the PLC memory area, but I need the list to be non volatile and with huge length, so it should use the compact flash. Each element of the list/buffer is a group of 100 words. Do you know if there is an easy way or some instruction that helps to develop this code? Thanks

Get a look to the "ASFT" instruction...you can built a FIFO or FOFI function. I don't think there is a limitation af word....try! Ciao, Mike
