There are two modes of operation available with the AD101: two-word opera-
tion and four-word operation. Although the method for reading in analog val-
ues varies depending on the operation mode, the binary-converted value of
each input point is input into the PLC in binary form. This data can be used
directly in binary form or converted to BCD for further use.
This section describes the internal connections of the Module, the AD con-
version method used, the IR bit allocations, the methods used to input analog
values, and special functions available. Refer to Section 4 Programming
Considerations for programming examples.
