I have seen systems both ways, the DC common:
1) Grounded
2) Un-grounded (left floating)
What are the pros and cons of each of these?
The reason I ask is because I'm fighting noise/grounding issues on a machine. I have a very good understanding about shielding/twisted pairs/isolation/filtering, etc. But this is the only question I have... to ground or not to ground the DC commons from my 24VDC power supplies?
