Error 288:47 Fail to online monitor s7 400 CPU

This is not the first time we online upload and monitor PLC program from S7400 CPU. After we upload the program from the CPU, we are unable to online monitor. May I ask what problem could it be?

 

I had tried the settings at PG/PC interface, but the error 288:47 still coming in.

I had tried all the transmission speed 19.2kbps, 187.5kbps and 1.5Mbps. But still unable to online monitor the CPU program.

You CPU has a Profibus network, and you are trying to use MPI to connect. Choose PC Adapter DP (Profibus) for the interface. The transmission rate, start with 1,5mb,

I check the model. This PLC comes with only one port MPI/DP. The only way to comm and online monitor is choosing the correct driver - Profibus?

Select this driver and comm with MPI cable?

If you are using a PC Adapter, it's not only a "MPI Cable" is't a lot more. Test with those settings, the are the standard setting for Profibus. You can check the setting of the PROFIBUS: Master system, and see what the transmission rate is, so you can select the same from PG/PC interface.
