Example
The following tables show the examples of values configured to the random-specified devices (plDev), data read to the read
data storage destination (psBuf), and the number of bytes of read data.

M0 to 13
T10 current value
LCN100 to LCN101
• Values specified to the randomly selected device (plDev)

Current value
All bits are OFF.
10 is stored in D10, 200 is stored in D11, 300 is stored in D12, and 400 is
stored in D13.
All bits are ON.
The current value of T10 is one second (10).
0x1 is stored in LCN100 and 0x10000 is stored in LCN101.

Description
All the bit devices from M100 to M115 are OFF.
D10=10
D11=200
D12=300
D13=400
All the bit devices from M0 to M13 are ON.
The current value of T10 is 10 (one second).
Lower bit of LCN100 = 0x0001
Upper bit of LCN100 = 0x0000
Lower bit of LCN101 = 0x0000
Upper bit of LCN101 = 0x0001
