I was just wondering, is the capacitor really necessary at the power supply connector to your MD series PLC? What are the major problems with leaving it off? I understand there might be a potential voltage drop with it not installed but and may help filter some noise. A strong supply voltage and current rating of the PS should be sufficent. What might I expect the PLC to do with out the installation of it. A small list of items to check for would be deeply appreciated.
Thanks
