VS070QS-1618MDM1 Integrated Machine Analog input/output
202403 (V1.0) 48
Note:
When the special soft element SM179 selects voltage mode output, if the
physical connection is a current-type connection, in which case there is still a
current output, and vice versa, but the output analog value is not the expected
analog value.
Different devices shall be matched with corresponding output modes,
otherwise unexpected consequences may be resulted.
D.2 Application example
1. Connect the voltage mode analog output D/A channel 1 to the voltage mode
analog input A/D channel 1. For details, see 2.3.7 Analog input/output
characteristics.
First, set SM178 (D/A channel 1 enabling flag) to ON, SM179 (D/A channel 1
output mode flag) to OFF and SD178 to 5000.
Then, set SM172 (A/D channel 1 enabling flag) to ON and SM173 (A/D channel 1
output mode flag) to OFF, you can see that the voltage output of D/A channel 1
has been given to the voltage input of A/D channel 1, i.e., SD172 = 5006.
