Are you passing a lot of information back and forth in this system. I am just curious because i made the mistake of using proficy me and quickpanels as the hmi's for all my control logix plc's in a new facility. I found the quickpanels to be absolute junk (data updte rates, proficy is horrble sotware). As they fail i have been replacing them with ab panelviews (which of course means rewriting the hmi apps from scratch, but i just cannot tolerate the molasses slow updates, and writing the same app in rsview ME takes about 10% of the time). In your particular installation, is there a need for fast updates on the hmi?
I would appreciate any insight on this because i still have 8 quickpanels that are alive and kicking (unfortunatley). I spent at least 50 hours trying to harass and threaten GE into providing a solution and finally just gave up.
Thanks in advance for any insight.
Funny...I gave up on Panelview Plus's for the same reason. They work well once they start up but 3-5 minutes on serial is horrendous (Ethernet is faster but still slow). In addition, the flaky ground problems and other unexplained strangeness drove me up the wall. After putting in about a dozen installations and having constant and unexplained problems with 50% of them (in addition to the slowness), I eventually went for Red Lion if I want just a basic HMI. Price is 1/2 of AB and 1/3 of GE and rock solid. But it is after all just a basic no-frills HMI to a degree (although still more capability than RSView ME).
As to Cimplicity, I've had great success for years with PE (haven't touched ME in a long, long time). I've got a 3200 tag installation with 5 servers (web, thin clients, database, and 2 redundant PE servers). I've switched from Panelized PC's over to $300 thin clients from HP (used to be Neoware) and never been happier. Hardware is rock solid and boots in 60 seconds compared to Windows, etc. Software behaves nicely, too. About the only problem I had is that if some how someone manages to "lock up" a "PC", old fashioned rebooting does not cause the intended effect. So I went into the policy system on the thin client server and set up an auto-logout after the minimum time interval (1 minute). So turning off a thin client for more than that time (roughly 2 minutes) gets you a reboot without knowing your way around menus. I still haven't figured out how they lock up in the first place and there's only one machine that does it about once every 3 months.
With this setup my costs are $1250 (Nematron NEMA 4 touch display)+$200 (NEMA 4 keyboard)+$1800 (Cimplicity TS license)+$300 (thin client) = $3550. About the same price as a Panelview Plus and about $1000 less than the equivalent Quickpanel, and I get effectively a full blown PC installation without the PC headaches. I do have to pay for a server but I'm up to about a dozen thin clients with no noticeable performance penalty. Microsoft et al estimate that I can push as many as 2 dozen or so thin clients before the server will become an issue.
