Im from PK. we have siemens Plc with single s135 Cpu 928, it has 32 k RAM fitted and also EPROM module but no backup battry. after power failure its data has been lost and we did lot try to reload it. we are new here to understand Simatic S5 inteface but we try to load its program file From PG 750 but Cpu did not go to run but stop slowly and BESP light up. Istack shows the LZF error and OB1 block in BSTACK. im not familer with s5 program loading but with the help of Siemens Guide Book and Training manual i load the program and these errors have come out.
After all i checked All the I/O modules (6ES 5451-4UA13) one of them is become faulty and its some ICs have been damaged. so i changed it with new one then a new Error shows ADF. then i rack out the cpu and then insert it the ADF error gone but CPU not go to RUN, and LZF error is Still.
Then i load the program file with other PG that has old Program file. then CPU goes to RUN but some Output modules blinking flip flop.. and plant still Not run.. plz help me and im waiting for fast, good and professional answer. u can ask me any questions about my problem.
