Analog Output


Recommended Posts

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.

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?
