• If an attempt is made to execute this instruction while the CJ1W-DA042V Analog Output Unit is being
initialized, it will not be executed and the Error Flag will turn ON. To ensure that the Unit is not being
initialized when this instruction is executed, use the High-speed I/O Unit Initialization Flag in a
normally closed condition for the instruction.
Example Programming
When CIO 0.00 is ON in the following example, the output SV for analog output 1 stored in CIO 2031 (in
the words allocated to Special I/O Unit with unit number 3 in the Special I/O Unit Area) is output from
analog output 1 of the CJ1W-DA042V Analog Output Unit with unit number 3.
