Regarding communication failure of MP377 12 key HMI

Dear sir,

I have MP377 12 key HMI It is working ok in my running machine but due to plant requirement I have modified HMI programme and compiled it found ok and runtime start without any error.

But When i trying to download modified programme in HMI i an facing communication error.

In set PG/PC I selected MPI/Profibus baud rate 1.5mbps maximum devices 126.and devices address as 1 in my programming PC.

In HMI setting i have selected same communication protocol mpi/profibus and selected devices address 1 as i have selected in set PG/PC.Baud rate is 1.5mbps.

When I start transferring project from wincc flexible to HMI I am getting error of check cable connection and settings etc. I have selected transfer mode from HMI and it shows connecting to host.

HMI is communicating on profibus with s7-300 plc.

Pls help to communicate HMI from PC.

Dear sir,

I visited this link in this link for profibus communication CP5512 auto is selected and in simatic panel profibus is selected.

But unfortunately this driver is not showing in my set PG/PC so I have selected Profibus active in set PG/PC and station address is 1 and tik mark on for only for master devices.Buad rate is 1.5MB/PS same settings on my programming PC and operator panel.

My simatic panel has address of 4.

No any run time error coming during compiling.

When I start transfer programme from wincc flexible I have selected protocol of MPI/DP and station address as 4.

I did same settings in simatic panel and kept it in transfer mode.

But when I click to project transfer following error is coming

Check cable connection etc.

Pls help me on that....
