If I am using a PLC that has a 24 VDC power supply is that enough to provide good power quality or do I need a 120 volt UPS feeding that 24 DC supply to have good power quality?

All products including the PS will have to be AB as that's all we are allowed to use at this company unless we need something that AB does not make or have a very good reason for not using AB.
Then you are good to go, the A-B power supply has VERY good filtering and regulation.All products including the PS will have to be AB as that's all we are allowed to use at this company unless we need something that AB does not make or have a very good reason for not using AB.
UPS is not required.
Sometimes a UPS can be handy if your plant is located in a remote area and you have power quality issues. We had a PLC5 that would sporadically lose its program, after talking with our integrator we installed a UPS we had (plug in style, but that's what we had) and the issue went away. We are now using the SOLA UPSs for our PLCs, they only maintain power for a few minutes, but that is enough to ride through most flickers and keep from losing data (positioning, product data that shifts with conveyor line, etc...).
