Writing Analog Output Data; Output Processing Timing - Panasonic AFPXHEAD4 User Manual

3.5.3 Writing Analog Output Data

Write analog output data for each channel into the "Analog output value area".
■
Sample program
If an expansion is made to the 1st unit, set as follows using the user program to write the
analog output values of CH1.
Write the digital values saved in DT10 into WY30.

Digital conversion values
Digital conversion values for each output range are as follows.
Output range
For -10 to +10 V, -5 to +5 V
For 0 to +10 V, 0 to +5 V
For +1 to +5 V
For 0 to +20 mA
For +4 to +20 mA

3.5.4 Output Processing Timing

● Analog output data of the operation memory is written to the analog output section at the I/O
refresh timing.
● The time required for the analog output section to convert digital data is 1 ms for every CH.
● The processing of the analog output section is not synchronized with the processing of the
operation memory. Therefore, the analog output section converts the latest data written from
the operation memory into analog values and outputs the converted values.
