Errors after Migration to TIA: How can i solve this indirect addressing problem?

Hi Everyone;

I have the same problem but i didn't solve it. İ migrate the s7-300 Step 7 v5.5 to s7-1500 tia v14. For a function block that you can see below the codes, program give me error that "ACCU 1 is not initalized. Access is invalid"

How can i solve this indirect addressing problem? What is the different for s7-1500?

Hello

About the Transfer instruction...

=> Use the "Transfer" instruction to transfer the contents of accumulator 1 in byte, word or double word format to a specified operand.

Try use the instruction 'Load' before it to initialize the accumulator content

 L "Tag_Value_1"

 T "Tag_Value_2"

Apparently TIA requires more discipline on coding... since it was possible  before on S5 or S7

I hope this helps
