4.3 Analog Output Unit (FP0R-DA4)
4-11
①
R9012 Switches the timing of writing data by the scan pulse realy.
②
Checks whether the lower limit value is within the data range that the unit can convert correctly.
③
Checks whether the upper limit value is within the data range that the unit can convert correctly.
④
Y2C
Output data switching flags for even numbered channels. Channel numbers are specified by
the two-bit switching flags right after setting conversion data by the transfer instruction F0
MV.
⑤
Y2D
⑥
Y3C
Output data switching flags for odd numbered channels. Channel numbers are specified by
the two-bit switching flags right after setting conversion data by the transfer instruction F0
MV.
⑦
Y3D
ⓐ
It is executed when the scan pulse relay is ON and written data is within the upper and lower limits.
Data for CH0 is set in DT0, and CH0 is specified by the output data switching flag.
ⓑ
It is executed when the scan pulse relay is ON and written data is within the upper and lower limits.
Data for CH1 is set in DT1, and CH1 is specified by the output data switching flag.
ⓒ
It is executed when the scan pulse relay is OFF and written data is within the upper and lower limits.
Data for CH2 is set in DT2, and CH2 is specified by the output data switching flag.
ⓓ
It is executed when the scan pulse relay is OFF and written data is within the upper and lower limits.
Data for CH3 is set in DT3, and CH3 is specified by the output data switching flag.
• In the FP0-A04-compatible 12-bit mode, Y2C, Y2D, Y3C and Y3D are used as
the output data switching flags. Note that the allocation is different from
that in the 14-bit mode.
