Part Number: TM4C1230D5PM

Tool/software: Code Composer Studio

I need to develop a ihm to work with a PLC  connecting   Canopen protocol.

I m looking  somebody that can help me.

I m using a lot tiva c  series and touch display .

Best regards.

    I suppose it's possible you will find a consultant or employee here but at the very least you should provide an indication of where the opportunity is and how to contact you for more information. I suspect TI doesn't want to encourage such offerings though.

    Someway - somehow -  "using a lot Tiva C Series" and "Post #1's arrival, just today" strain credulity - do they not?

    Thanks Robert

    By your answer, my english is not good, thanks for your attention to me.

    I'm a inexperient arm  student, I had making  hospitals equipment and a have to import some IHM and it is expensive costs for my reality in Brazil

    I would like to project a low cost IHM, using arm micro controles.

    Best regards.

    This does not seem like a good combination. Unless you are experienced in other microcontrollers and medical equipment.

    If you mean a Human Machine Interface then the fastest, cheapest, highest quality version for a small number would be to buy a commercial version.

    It sounds like you only want one or two.

    Yet the claim was "lots" - was it not?

    Hmm, I read that differently. It did sounds like a one off project. I read the lot as referring to other general use.

    That might change what makes sense as a solution but not the care required. A commercial HMI may still be cheaper depending on the definition of lots.

    Surely - any "commercial solution" makes the most sense - when numbers required are (relatively) small & "focused expertise" is unavailable...

    And - has not the "net" (now) made "anything possible" - by "anyone" - quickly AND "easily" - until they try, and then report, "Does NOT Work!"

    thanks for yours smart opinion, it is correct, but my case is diferente. My product is a hospitalar  system that use several IHMs linked    to master PLC, via ethernet..

    In my case the cost of the HMI is very representative in the cost of the workstation. All my competitors have their simple HMI with 4x4 keyboard and lcd.
    I've been looking for a long time to find a simple and inexpensive HMI on the market, but I have not found it at the ideal cost.

    As cost is key - you must determine the cost of importing "raw" HMI components (i.e. Lcd, MCU, pcbs, etc.) versus "finished goods."     Duty Fees, taxes, shipping costs & other charges must be fully & properly determined - only then can a "well considered" choice be realized.    (note that laws vary widely - depending upon "item classification" as well as country (both origin & arrival)   

    You must supply more information for those here to properly guide/assist.      Our firm has some involvement in custom HMI Design/Development - and can supply the raw components - if that yields cost savings.    (you must make that determination.)     

    Here are several HMI examples (very basic) which may guide you in the correct layout of your unique design:

    • Top is a small, mono, Graphic Panel w/3x4 keypad, 5 "soft" keys
    • 3.5" TFT w/4 "soft" keys & encoder for menu navigation & selection
    • small Graphic (128x64) w/"soft" keys & 4 navigation
    • our attempt at "world's smallest Operator Interface" - 2x8 Lcd & "5-way" Nav. Sw.
    • above Op. Interface "in the dark" - operating in an actual hospital lab environment

    Using this as a guide - you must identify type & size of display, keypad arrangement, encoders/Nav switches  etc.

    Thank you very much for your kindness and help. Their assumptions and these costs we have considered, the great problem of our country are the very high import taxes. We have representatives from all over the world who sell various types of HMI, but the values of freight costs and taxes make our product unfeasible.
    Today we have large network distances from the stations to the master PLC, and we use in each station a remote cpu of six inputs and four digital outputs, besides the HMI. Our stations have RFID networked modbus with the PLC master. We use three types of protocols Of communication, being canopen for the remote I / Os cpu, modbus for the RFID system, and ethernet for the HMIs.
    Using all automation with components bought in Brazil, of European origin. Our system works well, but with high costs.
    Our desire would be to buy the firmware IHM design with I / Os, and it is not a simple IHM, with ethernet, canopen and Modbus Rtu ports.
    best regards

    If I might humbly suggest that's putting too much of a burden on your HMI. Simpler and probably cheaper to have a concentrator device that does the communication on all of these various networks and provides the needed subsets of information via a separate connection to the HMI.

    Sure it's an additional board but by limiting the task of the HMI I suspect it will end up being simpler, less costly and more flexible.

    Constraining yourself to HMIs that can handle all three networks, especially simultaneously, is going to limit your choice to the most expensive ones.

    I addressed the "HMI" component requirements - as those will encounter: "Duties, taxes, shipping outrages." That "component aspect" of your design remains unknown & undefined.

    You've provided a beginning spec towards functionality - as you can imagine - even (more) detail (there) is required by those (potentially) able to assist. My (small) tech firm has sold to the (large) Brazilian firm, "Engevix" - they should have (both) staff & materials to assist you...

    Thanks for your suggestions, today we work separately even and our Ihm uses ethernet port and the remote cpus are separated and use canopen.
    But as I have no technical knowledge, I thought my IHM could have I / Os as well.
    I'll accept your suggestions and thank you. I need and look for a competent company or proficinal to help us define the project as a whole. We have almost nothing preset at the moment, we are trying to develop with tm4 tiva a simple HMI with lcs 2x16 to communicate with The plc master in this first phase, using the protocol for distances greater than 100 meters ..
    Thanks,

    It's possible and some even have PLCs with built-in analog and digital I/O but as you add more ports the price goes up. Also you would need to check that all communications ports can be active simultaneously, that's not a given.

    On the other hand, HMIs supporting MODBUS RTU/ASCII are common and inexpensive.

    Ethernet adds cost and security concerns. I know there have been DeviceNet based HMIs but I'm not certain I've seen any for CANOpen.

    Robert,
    A few years ago we contracted the design of a HMI, with communication protocol in modbus, we received the prototype and it did not work well. But now we want to give the beginning of the first phase of our project trying to divide in steps , and to discuss the project a lot.
    First Phase: Design and prototypes only of low-cost IHM, keyboard type and lcd communicating with plc master, with memory card (access login and shipping addresses, help configuration settings pages, ie list of Query of the points served by the customer's system).
    My goal is to produce the project in Brazil for a maximum cost of one hundred US dollars.
