I would like to configure a pulse timer which would not have a preset time value rather the value is fed from another control system through an analog output - analog input hardware connection. The AO will reside in other control system, then a 2-wire signal cable will be connected to a S7-300 PLC AI channel. How can I transform the incoming value into a S5 time format and feed in to TV input of a pulse timer?
One way, to scale the analog signal to values you
want(Result as Real) and check the result to represent "second
Round this value and Multiply this "double integer" value by 1000.
Then feed this value to FC40 as shown in attachment
