Hi every one,
I want to convert s5 95U with s7 cup but i have problem that old S5 CPU communicate with micro controller base another system. I have no access with micro controller system. Micro controller base system communication with s5 through on board cp524. My question is if, I change system with s7 and compatible CP of s7 with s5 cp524 with use of same addresses of DB and words like s5, then new s7 will communicate with micro controller with out any changing in micro controller system?
I have complete program of s5.
Best regards,
 
95U with CP524? :unsure:

First you must know the communication protocol and the settings on the S5 side.
Then you can check if it is replicable in S7.

Yes it is built in port on cpu. Can we detect protocol with s5 program? There is two function block FB1 and FB10. FB1 call in OB21 and OB22 with name CP24-DB.
In FB1 following command is written.
NAME: CP524-DB

AN F 0.0
O F 0.0
S F 0.0

L KF +0
T FW 100
T FW 102
T FW 104
T FW 106
T FW 108
T FW 110
T FW 112
T FW 114
T FW 116

L KF +60
G DB 12
G DB 14
G DB 202
C DB 12
L KH 0040
T DW 0

S F 0.1

and FB10 is call in OB1 with following commands,
;
NAME: DATI

C DB 12

L FW 100
T DW 11
L FW 102
T DW 12
L FW 104
T DW 13

T DW 16

C DB 14

Best regards.
 
Hi again!

Look at DB1, use 'Open Mask'
or open the DB in KC (ascii) format.
It may reveal important info.

There's no protocol info to be extracted from the FB1/10. Just data transfer.
