The RTC on my micrologix 1100 is randomly getting disabled. I'm not writing to the RTC any place in the ladder logic. The only reference to it at all is one rung that used a compare with  the .hr value. The manual says this is a 'read only' bit. The battery bit is never set. When I pull it up in RxLogix500 and click on the 'Set date and time' button(function file) the disable bit goes back to zero and it starts back up. Is there any chance this could be battery related even though the battery bit is not set?      

I'm using AuthSmtp as my mail provider and I need to be able to specify the port number. I can't find a place in the rslogix 500 channel setup to put the port id. Currently I'm giving just giving it the host name 'authsmtp.com. I did try the ip address with the port number xxx.xxx.xxx.xxx:xxxx but that didn't work either. Any thoughts are appreciated.

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
