Posted 23 Nov 2010 Hello, I am currently converting a machine from a FX PLC to a Q-series. Also, I've always used GX Dev. and now am using GX Works 2. At one point in the program I have an input interrupt. On the FX all I had to do was enabe interrupts (EI), use a FEND command, then to the left of the ladder went the interrupt pointer I501, indicating input 5 on the rising edge pulse. Top it off with a IRET and all was happy. On the Q I've tried to write it that way and it won't take the pointer. I've looked through the help and can't put my finger on it. Does anybody know where I can find this info? Thanks, plcdp Share this post Link to post Share on other sites
Posted 24 Nov 2010 You can't use regular inputs for interrupts on Q. You need the QI60 card. The first one will map to the first available interrupt numbers. Share this post Link to post Share on other sites
