*1. After setting the input mode, set the data writing time (waiting time) to 5 seconds or more for each
setting.
After this, if the same input mode is used, it is not necessary to set the input mode and waiting time
(T0 K50) again.
*2. The set input mode, convenient functions, upper/lower limit error status data automatic transfer-to
data register number, over-scale status data automatic transfer-to data register number, and error
status data automatic transfer-to data register number are retained in the 4AD EEPROM. For this
reason, even if the sequence program is deleted, the previously set functions will still be valid.

7 Examples of Practical Programs
7.2 Program That Uses Convenient Functions
Input modes of channels 1 to 4 will be
specified.
*2
The convenient functions will be set.
The upper/lower limit error status data automatic
transfer-to data register will be set to D100.
The over-scale status data automatic transfer-to
data register will be set to D101.
The error status data automatic transfer-to data
register will be set to D102.
Reads the digital values of channels 1 to 4 from
BFM#10 to #13 into D0 to D3.
Clearance of upper/lower limit error data
Clearance of over-scale data
The upper/lower limit error status data of each
channel will be output to Y000 to Y007.
The over-scale status data of each channel will
be output to Y010 to Y017.
The error detection signal will be output to Y020.
The setting error detection signal will be output
to Y021.
