8.2.2 Polling mode (input data set reading)
This section describes an example of communications in polling mode.
The 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 QJ71E71-100.
Read-target data

Logic result 0 (input data set 1)

CRC (input data set 2)
 Each module status (input data set 3)
(1) Parameter configuration
(a) Configuration required for the WS0-GETH
Configuration examples of network parameters required for communications in
polling mode are shown below. Configure these parameters using Setting and
Monitoring Tool.
The WS0-GETH requires no program for communications.
1) Creating a hardware configuration [for reading/writing]
Read the hardware configuration data from the actual MELSEC-WS safety
controller to Setting and Monitoring Tool or place modules in Setting and
Monitoring Tool according to the actual configuration.
