Posted 2 Sep 2020 I am curious as deltav is the only dcs system I have worked on. Do most dcs systems charge for use of input and outputs I find this outrageous Share this post Link to post Share on other sites
Posted 3 Sep 2020 Are you expecing a control system where the Input and output modules cost you nothing? Or is DELTAV charging a subscription fee per point and they somehow cease working if the fee is unpaid? Share this post Link to post Share on other sites
Posted 3 Sep 2020 We have the physical I/O we just need more licensing to actual implement the I/O in control studio Share this post Link to post Share on other sites
Posted 4 Sep 2020 I've worked with Omron, Toshiba, Rockwell, Schneider Modicon, GE9030 and Steeplechase PLC Systems and never heard of paying for I/O licensing unless it was for a Data Historian Option like with Wonderware, RSHistorian or OSISOft PI. Maybe some more experienced DCS folks can comment. Share this post Link to post Share on other sites
Posted 4 Sep 2020 Most DCS vendors have a license structure based upon Tags. They generally offer various tiers, 10K, 25K, 50k+. The trick is a tag can be almost anything, you need to learn to optimize, in otherwords, pack your booleans into a DINT as the DINT is one tag. Share this post Link to post Share on other sites
