I have installed a mp277 to a MPI network and it works great accessing information from three different PLCs.
I access MPI network and update PLCs using pc through ethernet to CP343 and this is ok.
But I cannot download new project to HMI WHY ????.

Direct access needed I think..MP277 has onboard ethernet controller..so the easiest way is to use crossover ethernet cable..

You can download project to MP over 'routing'.
That means, that you must include your MP in the S7 project and configure it in the hardware configuration.
Then the CPU (PLC) will know, how to 'route' communication from TCP/IP to MPI.
You can read about 'routing' in the S7 documetation.
