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.

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.

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.

Robert Adsett said:It sounds like you only want one or two.
Yet the claim was "lots" - was it not?
Wishful thinking proves not always (real) thinking... (and easily detected...)
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:
Using this as a guide - you must identify type & size of display, keypad arrangement, encoders/Nav switches etc.
ANGELO LAGUARDIA said:and it is not a simple IHM, with ethernet, canopen and Modbus Rtu ports.
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.

ANGELO LAGUARDIA said:But as I have no technical knowledge, I thought my IHM could have I / Os as well.
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.
