Device on Mitsubishi PLC

[Tom749 0]

I am programming PLC code using Melsec Q series for a conveyor line system. My new current system panel(Q series) is added to the old system panel(A series) for the upgrade of the conveyor line. I am analyzing the old system's PLC code now. I have one question about the attachment as following. What is the meaning of the attachment PLC code? It looks like some communication function PLC code. Is there any excellent engineer for an advice for me? Thanks for your help. Edited 13 Oct 2010 by Tom749
