All kind day!!! I need to interrogate a flowmeter (a signal 4. 20мА), only it is necessary to interrogate time in 600 seconds.
I want to apply to this business ОВ32 (from it to interrogate a flowmeter).
In properties CPU, in tab Cyclic Interrupts-> OB32 there is 1 second by default, the maximum that can be made it to expose for 60 seconds, and it is necessary for me 600....
Prompt please, can eat other ways of the decision of this problem?
Thanks all answered!!!
Excuse for rough transfer.

To my mind the easiest way would be to use timer (TON) and write value of mentioned AI to some data block or memory area. Next step would be resetting timer.
По-моему самый простой способ - использовать таймер на включение, записать значение аналогового входа в дата блок или ячейку памяти, сбив таймер следующей инструкцией
