Fig.App.5 shows a program example where buffer memory addresses are replaced
with I/O signals in the program for reinitialize the Ethernet module.
*1
When the I/O signals of the Ethernet module are X/Y00 to X/Y1F
* 1: The safety CPU module cannot read the current operation setting. Therefore, all operation setting
items need to be specified. When specifying these items, do not change the current setting for the
items in the dashed line.
