Hi all, I've been lurking around here for a while but now I thought I'd give posting on here a try! I'm using a couple of dozen E710 HMIs (of various ages) ranging from v4 to v6 firmware, whenever I programme the HMIs I set the E-Designer software to v4 in order to cover all units. This has been trouble free for a couple of years, however I went to upload a new programme but the guy who wrote it set the E-Designer software to v6 and used all of the new features! Is there anyway I can update the HMIs to be the latest firmware? It gets worse, I went to the Beijers website, downloaded what I thought was a new driver, uploaded it to the HMI and now the HMI's locked up and won't do anything!!! Any ideas would be gratefully received.
