Understand the S5 whole program

Dear Experts

I want to understand attached S5 whole program. can anybody tell me where the program starts and all details. can i simulate this program to understand the working. can i see comments with any software. i want to understand from start of program. what is the S5 procedure to start the program. actually i want to understand the flow of whole program.

Dear Sir

I want to understand the flow of program. where first start the program. where machine motor parameter are stored in the program. on this forum Mr.Fritz read this program and tell me the location of 4 digit numeric password for four different access level. like DB10 DW 42- DW- 48 has 4 digit numeric password location for 4 different access level but when i tried this password in HMI it is again saying that wrong password. now i myself want to understand that how Mr.Fritz understand that DB10 DW42 to DW48 has 4 digit numeric password. now u understand or not ... there is many other motor parameter which are also stored in this program. so no i want to understand the whole program. there is 4 section of machine and i first want to know where is the location of data of first section in this program and next second section.

 but currently main problem is to find out the 4 digit numeric password for 4 access level stored in this program.

DB10

DW42=3330

DW43=3031

DW44=3330

DW45=3032

DW46=3330

DW47=3033

DW48=3235

I tried all above values on HMI where it is asking to enter password for Machine Data but it is saying false password. now help me.

As you told us that Fritz already starts to analyse the program,
I think it is the best idea to wait for Fritz further informations.

The answer of this problem is located in another thread with the subject S5-135U CPU 928Password for Machine Data on HMI is stored in this program.

Dear Sir

 ok can u suggest me any idea to find out the any best simulator to understand the flow of whole program. which i already told u.

regards

I do not know any Simulator for Step5.

Perhaps some other friend here has an advice...

DW42=3330

DW43=3031

DW44=3330

DW45=3032

DW46=3330

DW47=3033

DW48=3235

I guess it is hexadecimal representation of characters.

30 = 0

31 = 1

32 = 2

etc...

So the first one would be: DW42+DW43 = 3001

and DW44+DW45 = 3002

and DW46+DW47 = 3003

and DW48+DW49 = 25..

Have a nice journey in S5 era!

Dear PlcforEver

sir it is already told by Mr.Fritz but can u t ell me how u judge that this is in ASCII code ?? any idea. but my this problem has been solved by Mr.Fritz. My another problem is that how Mr.Fritz reached the location of password in the program. how he decide that in this routine the password is save. i understand this thing. can u tell me ????
