17-8 Startup Operation
After the power is turned ON, analog option board starts the initialization process. If the initialization fin-
ishes normally, the initialization completed flag in related status area (Refer to 17-4-2 Auxiliary Area
Allocation: A435) will be set. Therefore, status monitor content must be added in ladder. Only when the
initialization process has finished, user can use the A/D conversion data or write the output data.
The analog input data will be 0000 until the initial processing is completed.
It takes about 3 seconds from the CP2E CPU Unit running to the Analog Option Board initialization
completed.
