8.4.8 Writing Analog Output
The following example describes how to write analog output.
Example 1
Output the data written into DM0000 to analog output ch. 1 of the KV-AN6 module
No. 1 (±10 V output range)
•
When input 0000 is ON, +10 V is output.
• When input 0000 is OFF, -10 V is output.

Example 2
Input trimmer variable data by using analog timer ch. 0 of the KV-300 CPU and
output voltage to analog output ch. 1 of the KV-AN6 module no. 1.
•
When input 0000 is ON ( 0 to 10 V), voltage increases when trimmer of analog
timer is turned clockwise.
• When input 0000 is OFF (0 to -10 V), voltage decreases when trimmer is turned
clockwise.
• Output range of ±10 V is used.

0 to 10 V
When input 0000 is
ON, outputs 0 to 10 V
to analog output ch.
1.
When input 0000 is
OFF, outputs 0 to -
10 V to analog
output ch. 1.
