Function Block Diagram S7 1200

[Shahadat]

Hi, I have attached herewith one image which our programmer has been used in S7 1500 PLC. Now we need to use the same instructions in S7 1200 PLC. But we can not able to find any solution. Can anyone help us to find any solution which instructions shall we use instead of that in S7 1200?

Wouldnt it work to do it like this?

"HMI".IBN_EQ := ("HMI".IBN_Enter = "HMI".IBN_Code);

Is it possible to use any instructions instead S_COMP with the FBD language?

Read the help, S_COMP is not supported in the S7-1200 Roll your own function using the SCL code provided above and then call that in your FBD

You should also be able to add one "rung" of SCL to your FBD block, could simplify things if you don't need to do it often enough to make it's own FC
