Gabriel Franco Posted August 31, 2016 Report Share Posted August 31, 2016 Hello all, PLC: V1210, OS 3.09.06 Yesterday I got a black display with "no application" error. I restored it, selecting Application from SD Menu in INFO mode (Only application). All information remain unchanged (Datatables and operands) and SB8 (Battery low) = 0. ¿What could cause it only application was lost and not datatables nor operands?

MVP 2023 Joe Tauser Posted September 7, 2016 MVP 2023 Report Share Posted September 7, 2016 I've had that happen and the cause is unknown and mysterious. The battery usually tests good. When you downloaded the program, did you select "download and burn"? This will retain the program for sure. Joe T. Quote Link to comment Share on other sites More sharing options...
MVP 2023 Flex727 Posted September 8, 2016 MVP 2023 Report Share Posted September 8, 2016 Do you have a Snap-In module attached? I've had that happen when the module is not fully engaged. 1 Quote Link to comment Share on other sites More sharing options...

I've had that happen when the module is not fully engaged. That´s why I am avoiding as much as possible the snap in modules. If you have a lot of wires attached and you need to open and close the cabinet door then its better to just have the HMI. Quote Link to comment Share on other sites More sharing options...
DaveE Posted September 12, 2016 Report Share Posted September 12, 2016 Very strange My customer had the same thing happen yesterday on a V350 with an ethernet snap in installed Quote Link to comment Share on other sites More sharing options...
MVP 2023 Ausman Posted September 13, 2016 MVP 2023 Report Share Posted September 13, 2016 Re the snap-ins, I've always been a little concerned as to how easily they fit onto the main unit. For this reason I run a strip of reduced width gaffer tape around the seam wherever possible. I know it isn't supposed to be necessary, but it just felt "right" given the "looseness" of the fit, taking into account the number of pins engaging. Easily removed as necessary but holds things together well. Never had issues. My checkups on systems routinely include an annual remove/refit/wiggle of all connector blocks. cheers, Aus 1 Quote Link to comment Share on other sites More sharing options...
Gabriel Franco Posted September 14, 2016 Author Report Share Posted September 14, 2016 Thanks all for reply. The problem happened only once, two weeks ago. The last change I've made, one month ago, didn't download all and burn, just download. However I keep a copy of application in SD which allow us to recover it. There's a snap-in module attached. The past weekend, I perform a brief maintenance to PLC: Cleaning, dust blowing, battery check, re-attach snap in, check power voltage, full clone to SD. So far, everything OK Quote Link to comment Share on other sites More sharing options...
