Device from which the value is
read
Word
Explanation:
1. The values in the devices specified by the value in D are read into E0~E31, and the value in D
decreases by one.
2. The execution of the instruction involves thirty-four devices, and the last two devices are for
system use. If the instruction is executed and the number of times the data is stored is n, which
is the value in D, the data in D+34*(n-1)+1~D+34*(n-1)+32 is read into E0~E31, and the value
in D becomes n-1.
3. The value which is stored last in the device specified by the value in D is read first.

For system use
Example:
When X0.0 is ON, the value in D0 is set to 0, and the values in E0~E31 are transmitted to D1~D32.
After the execution of FB0 is complete, the values in D1~D32 are read into D1~D32.
