I think you would find this a much more neater solution. Querying a Time-of-Day Interrupt with SFC 31 "QRY_TINT"???? how to use it?

I need monitor a bit check off comunication, in the partner device the system generate a bit clock 0,5sec. In my side i need monitore this bit and if this not change status in 2sec for example fail is detected. .... Hey, NewTech I propose using of FB instead of FC and use of IEC timers in instances.Printout of this new FB is attached. You can use this FB in your program as many times, as you want (of course, each time with different instance!) and it is completely without absolute addressing....... Complete example project follows..... (there is only 1 attachment allowed with 1 post??) Have fun! uel123 Attachment Monitoring change FB351.pdf (95 Downloads)
