I am looking at the ReadWriteEEprom FB and see that one of the elements is "pbyData". which is the pointer to byte that is usually set to 2048 bytes. Since I am setting the alias address to the EEprom only (EEprom address 16#0012), I would assume that what I am writing is 2 bytes only. </p> <p>Does the pbyData have to be specified as ADR(myArray) where "myArray" is the 2 bytes of the alias address?</p> <p>How is the best way to set this element of the function block?</p> <p>Thanks in advance</p></div>kurt9Mon, 18 May 2026 18:17:23 -0000https://forge.codesys.com872cd7f5bbad3b3892a2c7248b504ec9f3624004
