8.2.4 Auto update mode
This section describes an example of communications in auto update 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. The WS0-GETH automatically
sends input data sets to the QJ71E71-100 at 5000-ms intervals.
Read-target data

Logic result 0 (input data set 1)
 CRC (input data set 2)
 Each module status (input data set 3)
