Sarkis Sarkissian Posted July 10, 2019 Report Share Posted July 10, 2019 Hello, I have a JZ20-J-UA24, and I want to send a voltage analog output of 5 volts. I did configured my hardware where i set a store value of 5 in my MI to send out 5 V but its is not doing so. Any ideas why? Quote Link to comment Share on other sites More sharing options...
Cam Posted July 10, 2019 Report Share Posted July 10, 2019 Yes. The value in the linked MI is NOT the voltage you want out of the output, a value of 5 in the MI is not going to reference pretty much 0 volts The output has a 12 bit resolution. meaning 2^12=4096 so your MI can have a value of 0-4096 0=0V on the output while 4095=10V 5V would be around 2048. If you want to put a value in a MI and have the output respond to that IE 5 in the MI gets you 5V you need to look at the linerization function.

MVP 2021 Joe Tauser Posted July 10, 2019 MVP 2021 Report Share Posted July 10, 2019 It's not that simple. The analog output is controlled by a D/A converter in the PLC. Go back and look at the specifier's guide for the -UA24 under that analog outputs section. If you have the output configured for voltage then you need to pump a number from 0-4095 to the mapped MI. So a value of 2047 should give you 5 volts. This level of questioning indicates you need some basic instruction on how PLCs work. Can you work with the person you bought this from to get some help?
