Hello Saggy;
What do you think your next move should be, based on the DIGSI message?
Hope this helps,

Hello dchartier,

i will configure once again the relay with DIGSI

then let you know

Hi Saggy,

I'm trying to connect Profibus communication between CPU 315-2DP and relay 7SJ62 but I dont know use mapping file and how to configuration in DIGSI 4 software and Simatic S7300. Could you show me the way to do it, please! Could you send to me some pictures about screen of software for more detail. Many thank!

Hello Huyhung;

All these subjects have been covered in this thread already, so it would be better if you started by reading the posts that precede yours, and opening the proposed links and documents.

A few notes: a mapping is a selection of values that can be transferred to a Profibus master in a single telegram. You must select one of the available mappings before you open Digsi or Step 7, as you plan your application; note how many bytes this mapping will use over Profibus..

When you have selected how you are going to exchange data with the master, open Digsi and in the Communications area select the same mapping for Profibus-DP exchanges.

Next open Step 7 and in the Profibus configuration first integrate the 7SJ62 gsd file, then drag an icon for the 7SJ62 to the Profibus master; then select as many modules are necessary to obtain the number of bytes to be exchanges with the selected mapping.(both input and output bytes). For example, mapping 3.1 requires 100 bytes IN and 9 bytes OUT. See the attachment below for a sample configuration for mapping 3.1.

Hi pdas,

did you notice that this topic is 8 years old? Please tell us which issue you have (and which software, plc, etc you are using)

Hello pdas;

If the information you are looking for is related to the Siprotec 7SJ62 Profibus files, you can find them all here (gsd, mappings, DIGSI driver):

If it is for a different relay, Siemens Energy ( the Siemens division that develops, manufactures and distributes protection equipment) provides access to its documentation at the following address:
