ASCII Char
This format is used to represent a 16-bit register in the PLC as a corresponding ASCII
character. If the Number of Digits in the OITware-200 Register Monitor Editor dialog
box is set to 2, the OIT reads the 16-bit register as two 8-bit ASCII characters and
displays them. If the Number of Digits in the OITware-200 Register Monitor Editor
dialog box is set to 1, the OIT reads the lowest eight bits of the 16-bit register and
displays one ASCII character. If the data in the PLC register does not correspond to a
displayable ASCII character(s), the OIT continues to show the last displayable ASCII
character(s), or if there never was one, a space.
