Identification data for PROFIBUS DP
Definition
Identification data is information stored in a module which assists the user when:
● Checking the system configuration
● Locating hardware changes in a system
● Correcting errors in a system
Identification data enable modules to be uniquely identified online.
STEP 7 displays the identification data in the "Module Information - IM 154" and "Properties"
tabs (see STEP 7 online help).
Reading the identification data with DS 255
The IM 154-1 DP/IM 154-2 DP High Feature interface modules (6ES7154-1AA01-0AB0/
6ES7154-2AA01-0AB0 and higher) also support standardized access to identification data
using DS 255 (Index 65000 to 65003). For additional information on the data structure of the
DS 255, refer to the specifications in the PROFIBUS Guideline - Order No. 3.502,
Version 1.1.1 dated March 2005.
