converting an existing S5 program to S7

Ryszard_K

Hello.

I have a problem with the conversion of S5 to S7. LIR The program includes instruction and TNB, which are not automatically converted.
The program was written for the S5-95U and I want to convert it to the S7-314.
Function blocks FB 110 and FB 111 (FC 30 FC 31 and after conversion) are called by the open DB 2.
What will be the contents of ACCU 1 and ACCU 2 after executing LIR 0 - such as FB 16 (FC 14) Segment 2?
On which area of data is executed statement TNB?
How to replace LIR instructions and TNB in S7?
I enclose portions of files after conversion.

Thank you in advance for help.
