I Googlied: "PLC and DCS" and this is what I found:

To me, if it's a gas distrubution network, I would guess you would want a more 'smarter' system than a fairly limited PLC system and therefore you would want a DCS. The article talks a bit more about them.

Thank you for your co-operation and I hope for us to be in contact forever.
