Offset is the word offset into the file (low byte, then high byte).
Size is the size of data to read:

protected typed file write
Writes data to an open file in a MicroLogix 1000 or an SLC
processor. For MicroLogix 1000 processors, this command can be
used to update the Terminal ID by writing two bytes. (To do this,
size = 02h, the tag = 4176, the offset = 0000, the file type = 90, and
the two bytes of data contain the terminal ID, low byte first.)
