Hi everyone,

I have a short question about BLKMOV instruction, illustrated in the image below. I have the same piece of code in STEP 7 (ET200S) and TIA Portal (ET200SP).

In the first case, BLKMOV instruction doesn't allow me to put String data type as an output parameter, and in the case of TIA it does allow...

I need this function in STEP 7, so - how to transfer string value from the temporary variable to the output variable (both of type String), if not with BLKMOV instruction?

EDIT: Forgot to mention that the variable at the "DSTBLK" assignment is an OUT variable of the FC.

Kind regards,

Aleksandra

String works perfectly when you use variables in that style in TEMP area or even DB area in SFC20 .Check the attached file and video for more info.

 Hello hdhosseini,

 Thanks for answering but my intention was to make universal FC for transferring an array of bytes to string. That's why I need OUT variable of type String... I don't need a temp variable or a specific   variable from a specific DB.
