Posted 6 Feb 2009 Dear All, I have here 4..20mA input and depend on this input, i need to generate from minimum 2 to 200 pulses per minute. It something like a PWM output i think. With input 0f 20mA then i need to generate 200 pulses/min. Do Omron have standard block for this application? dsc Share this post Link to post Share on other sites
Posted 6 Feb 2009 I am not aware that a FB is available for this purpose. Use one of the SCALING instructions SCL, SCL2 or SCL3 to convert the data from your incoming 4-20mA signal to a SPD [pulse train output]. The W451-E1-03 CP1H/CP1L Programming manual has very good examples of different methods of applting the scaling commands to from Analog Inputs. Section 3-17 Data Control Instructions. Section 3-20 Covers the Pulse Output and PWM instructions. Get the manual, read it, write a program, test it with CX-Simulator. If you are still in trouble THEN post your questions.
