1756-cnb User Manual
AM #1 mlkramer2 Member Join Date: Jun 2008 Location: Detroit Posts: 9 ControlNet Communications Timeout Problems Any help on this would be GREATLY appreciated! I have an AB controlnet network with ten racks. I am 1756-cnb/e error codes occasionally getting failures, currently about once every two days where a rack or racks will simply stop communicating. The only way to bring them back is to reset the controlnet bridge module (pull it out and put it back in). This network is controlling a reheat furnace which can be up to 2500 degrees, so these comm issues can be VERY unpleasant. I sometimes have multiple racks at various points along the network fail simultaneously, rsnetworx for controlnet tutorial other times it will be just one at any point along the network. I set up some error trapping logic today and had a rack fail this evening and it gave me fault codes of 515 and 516, which I believe are communications timeouts. I used to have continuous errors of all kinds on the network, until we went through and replaced every connector (sloppy installation work) and now I don't get any until I have a complete failure of a rack. Does anybody have any fixes for this or common experiences? Is there a way for me to increase the timeout time?

Eliminate possible bad backplane bridge chips. This is RA product service advisory from May 2007 that every RA technician and engineer is familiar with. 2. Check for more noise or bad packets that may remain after your media repairs. Use the ControlNet Netchecker and a pad of paper to note the signal conditions as the system operates, and take notes if the signal changes when specific machinery is o

After upgrading one of them recently we are getting a yellow triangle on the I/O Tree and the fault reads (Code 16#0317) Connection Request Error: Connection not scheduled. Upon further investigation I find that the "slave" PLC which went from V12 to V15 still lists the "master" which went from V12 to V17 as a V12 on the properties tab. I've scheduled COntrolNet previously, but not in the past 5 years. I'm assuming I have to update the RSlogix Files to show the correct Firmware versions on the properties tabs and then schedule the network with RSNetworx for ControlNet and probably need all PLC in PROGRAM. Any hints or sugestions to jog my rusty memory are appreciated.

I was lookng into re-scheduling before and
