Dear all,

I am using a s7 400 h system with CP341 via ET 200M. CP 341 is acting as a"Modbus Slave". I am taking reference of the sample project . But i am getting error 16#02,at the same time error bit is also high.

Find the attachment.

In diagnostic buffer of themodule it is showing that module is ok .

Thank you very much for your response dear  Kaulquappe.

 1,But LADD i have cross checked. It is okay

2.Secondly CP is parameterized as Slave.

Please find the attachment

1.No Tx and Rx led is blinking . which means that till now communication parameter is not active. I am not getting further what should be tried. 

2.From where should i get the error description as it is not available in helpfile and in Manuals.

Dear Kaulquappe,

1.Thank you dear for your support for this manual. I checked the error codes.

2.I have already checked the diagnostic buffer. Kindly find the attachment

3.Even I changed my LADD to 272 ,apply it in program. Found same err.

4. I could not construe "store in PtP ". Do you mean to save it ?

Thank you very much dear kaulquappe.

As per my experience I have tried the following

1. I have assigned directly the decimal value of module(CP) address to LADD.
2. Converted the value to hexadecimal and assigned.
3. Changed the default value of module address ,assigned a new address. Applied the same in program
4. Moved the module address to a memory word in the first scan of CPU using OB 100, and assigned it to the LADD.

But same error is there.
