MicroLogix 1100 internal clock?

[hboyer90 3]

Hey guys, sorry for all of the newbie questions, I had 1-2 years of PLC training at a tech school, and then I got a job where I didn't use my knowledge at all for 2 years, and now my current job is all PLCs, and I have forgotten some of the stuff I learned, but it's coming back to me, so I appreciate all the help with the stupid questions. Anyways, here is my question. I am using a MicroLogix 1100 running RSLogix 500 to collect data on a few of our machines about scrap parts and run time vs down time. I just have some basic inputs hooked up to it. I need to be able to send the data to an integer file at the end of every shift, and then reset the current data (easy enough for me, at a certain time I will use a MOV function to move the info from the timers and counters to integers and then use a RES function to reset everything that I want). Anyways, my question is how to I tap into the free running clock built into the MicroLogix 1100? I see that it is S2:4, but I am confused how to use it or set it. I just set one up on a SLC 5/05 and that was super easy, I just set the time while it was online, and then used 3 different COMPARE functions to tell it when I wanted to move/reset the data (I used S:40, S:41 and S:42). Anyways, I can't seem to figure out how to tap into this clock on the MicroLogix 1100. Can anyone help me with a "dumbed down" step-by-step guide. I just want data sent at 6:30, 14:30 and 22:30 and then data reset 2 seconds after each of those times. Any help is truly and honestly appreciated and very useful. Thank you in advanced. Howard
