Detailed Description   
2.4 Starting up the PLC program 
  PLC Basic Program Solution Line (P3 sl) 
2-12  Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0 
Procedure 
The basic-program blocks are copied using the SIMATIC Manager and File/Open/Library. 
The following components must be copied from the library: 
•  From the block container: FCs, FBs, DBs, OBs, SFC, SFB, UDT 
•  Source_files (from the source container): GPOB840D 
•  Possibly MDECLIST, HHU_DB and others 
•  The symbols table (from the symbols container) 
Compatibility with STEP 7 
There are no dependencies between the basic program and current STEP7 versions. 
2.4.3  Version codes 
Basic program 
The version of the basic program is displayed on the HMI version screen along with the 
controller type. 
The controller type is encoded as follows: 
 
Left-aligned decade of DB17.DBD0 (byte 0)  Controller type 
 02  SINUMERIK 810D 
 03  SINUMERIK 840D (561,571, 572, 573) 
 04  SINUMERIK 840Di 
 03  SINUMERIK 840D sl (710, 720, 730) 
User program 
Users can also display their own PLC version codes on the HMI version screen. For this 
purpose, a data of type STRING containing a maximum of 54 characters must be defined in 
any data block. The data can contain a text of the user's choice. Parameter assignments for 
this string are made via a pointer in FB1. Parameterization requires symbolic definition of the 
data block. See the FB1 block description for more information.
