END Refresh Type
The operating status of each analog input channel is stored to a data register, such as D761 or D767, allocated to analog
input channel 1 or 2 on analog module number 1 through 7 depending on the mounting position.
The analog input operating status data is updated whether the CPU module is running or stopped. When the CPU module
is running, the update occurs at the END processing of every scan or 10 ms, whichever is longer. When the CPU module is
stopped, the update occurs every 10 ms.
Ladder Refresh Type
The operating status of each analog input channel is stored to a data register determined by the data register number
selected in the Configure Parameters dialog box of the ANST macro.
