Yokogawa fcs revision

Any DCS I've been around required purchasing a license for the current version and maybe licenses for interim versions as well. Upgrades are the lifeblood of a DCS, a continuing revenue stream for the manufacturer. You need to check with Yokogawa.

Hi David
First of all I appreciate for your reply.

We have 5 fcs. All were revision 3.5.5 recently we executed offline download on 2 fcs which caused their revision changed to 3.5.0
My questions are:
How we can upgrade their revision to 3.5.5 same as before offline download?
Does upgrading Revision of a FCS means upgrading its firmware ?
Is it possible to upload fcs data and store it for using later?
