9. BINARY INPUT OPERATION FUNCTION B-63322EN-1/01
-56-
• Bit 3 of parameter No. 7609 = 1 ...
Uses auxiliary functions.
(The data length is [2 * N + 5] bytes.)
(7) When the parameter is set to use auxiliary functions, specify the
auxiliary functions to be used, using parameter No. 2034, as
follows:
• "0"... Second auxiliary functions
• "1"... Miscellaneous functions
• "2"... S functions
• "3"... T functions
(8) The following data formats can be selected for the auxiliary
function, using RDS (bit 2 of parameter No. 7609). (Specify
data using the bits marked with the asterisk (*) and specify
whether the data is significant using the MSB.)
• Special format (bit 2 of parameter No. 7609 = 0)

When the MSB is 1, the data specified with the bits marked with the
asterisk (*) is sent to the auxiliary function, described above.
After the time set for parameter No. 2010 has elapsed, a strobe signal
is sent for the time set for parameter No. 2012. The system does not,
however, wait for FIN.
(9) The check byte must be the result of adding together all the other
[2 * N + (0 or 4)] bytes in byte-by-byte basis, with any overflows
of 8 bits or more removed.
MSB = 1: The data is significant.
MSB = 0: The data is not significant.
MSB = 1: The data is significant.
MSB = 0: The data is not significant.
