Hi TJF1960, I had similar problem of random reboot.  After using shielded cable for 1-wire sensor, problem largely went away.  See my post on 11-24-2013.    Niandong

I am a Comcast high speed internet user, their smtp service works.   Host: smtp.comcast.net Port: 587   nd_liu 

I am having the same problem with both of my boards.  Changed port from 587 to 465, did not make any difference.  Email notification remains down, something happened at Yahoo's end.

Just want to report where the root causes are of the 1-wire bus triggered PLC reset.    First, I replaced the old telephone cable with CAT5 cable.  It did not fix the problem.   Then I tested each of 3 temp sensors on a short cable, they all run reliably at least a few days without resetting...

My telephone cable is solid core, but not twisted pairs.  I will try CAT5 cable first.    Thanks for suggestion!

Thanks both Tschmidt and CAI_Support for their suggestion and explanation, it totally makes sense.      My board was mounted in basement, is about 3-4 ft from noise sources, such as house furnace, a freezer and a dehumidifier.  All 8 digital Inputs were connected to Noise Suppressor DLP-20-6V15...

I think I finally found the culprit of the reset problem, it is the 1-wire temperature sensors channel. I tweaked data sampling time from 10us to 25us, did not notice any improvement on reset. But after I completely disconnect temperature senors from board, the reset problem went away. The board...

I am purchasing a replacement board from Ebay, will send this board to you after installing new board.  Thanks for the help!

In the past a few days, after board resets, it also lost the PLC program and Notification parameters that were stored in EEPROM.   Is it an indication that the board is dying?  In term of programming, I have checked the callsub stacks, I do not think I went beyond 7.   Very frustrated with board...

Hi CAI_Support, Thanks for loading my program into the testing board.  When board resets, it runs INITIA once before enters main loop (LOOP1).  There is "Email EM7" command in INITIA, I will receive EM7 email, which indicates board has been reset.  I use the counter to measure water usage, the...

Any test result?  I rewrote the program in a couple different ways, still have the same intermittent reset problem.  Any suggestion on how to track it down?

I have been on and off working on my webcontrol PLC based home monitoring system over last 4 months, by reading manual and posts from experts, I gradually got a grasp on PLC programming and started building up the functionalities of my system to meet our needs.  Now the complexity of program or...
