When IP Settings is set to "Use special data register to configure the IP address" and DNS Settings is set to "Use special data
registers to configure the DNS server addresses" in the function area settings, the values that are set on the HMI module when the
FC6A Series MicroSmart power is turned on and when special internal relay M8184 (HMI module network settings changed trigger)
is turned on are stored in the following special data registers.
Checking the HMI module network settings
The current HMI module IP address, subnet mask, default gateway, and DNS server addresses can be checked with special data
registers.
