Dear Colleagues,

good evening I just want to ask if someone here have code or know commands equivalent of FieldWrite and FieldRead of TIA Portal of S7-1200. I need this because I have a task of Converting Strings to Character and Place this characters to a cretain Data block, I found same solution https://www.automation.siemens.com/WW/f ... =en#238792
but the code is written in TIA Portal but it uses FieldWtire and FieldRead which I cannot find in S7-300 programming. Thank you very much in advance.


Best regards,
Rey
