    Touch panels

    I have a job coming up that the engineer specified he wanted a color touch screen station mounted in a mechanical room to view the Niagara system for emergency control of the system. Simple enough to find a touch screen industrial PC that has windoze on it and a web browser. The difficult thing I am finding out is that he calls out for the HMI to have dual network adapters. So far I've only found one place I can get one with the dual NIC's, but I'm starting to think that the dual adapters are made of gold and diamonds for the price.

    Anyone have any suggestions on suppliers?

    What is the intended function of the second NIC? Redundancy?

    I'm with DDC_Dan....WTH? Was the Engineer confused and meant to put the dual NIC on the JACE?

    In the industrial automation world redundancy is a lot of times the rule of the day and budgets are much higher.

    If you need a touchscreen with dual NIC's I have used these with JACE's before with no issues.

    Pricing varies depending on size, memory, processor etc. Most run on flash ram. I usually just have a small flash card for the OS since it is just for a web browser.

    Dual network adapters are for redundancy. It's quite the project actually. It was all specified for a Niagara server, bacnet IP controllers which he was adamant about them being POE, but I was able to talk him down from that ledge when I explained that we would still need power supplies for all the peripheral devices on the AHU's. I guess some snake oil salesman really impressed him with the delta POE VAV controllers. Original scope called for everything being dual NIC's, but cost ended up driving us to use the easy-IO controllers instead of the original 47 Jaces.

    Thanks controlgeek. I'll get ahold of them and see what they can work up for me. So far $4k seems to be the going price for these things which is mind boggling considering the fact I can build a mini-itx with a quad core I5 and dual nics for less than $500. Too bad I couldn't get a raspberry pi or a beagleboard with dual network adapters on it and stick it in a stainless box. On the other hand, I could get one of those and use a usb-ethernet adapter. I just don't want the liability if something were to go south.

    I know the Loytec touch screens have dual nics on their 12" and 15" screens.
    I am sure you can get them for less than $4k?!
    They are Bacnet and OPC compliant, not sure if it's what you are looking for though?

    To be honest, I didn't realize that the L-VIS had dual network adapters. I've sold and installed a few L-INX in the past, but never had a use for the L-VIS till now. While having to build separate graphics, is a bit redundant, it fits my need and the price is right. Thanks guys!
