8.3.2 Polling mode (input data set reading)
This section describes an example of communications in polling mode.
The Built-in Ethernet port QCPU reads MELSEC-WS safety controller information
(e.g. logic result, CRC, and each module status) from the safety controller through
communications between the WS0-GETH and the Ethernet ports of Built-in Ethernet
port QCPU.
Read-target data
 Logic result 0 (input data set 1)
 CRC (input data set 2)

Each module status (input data set 3)
