Unmapped parameter
read response
This is the value returned by the Gateway if the EtherNet/IP master
requests a register with no data assigned to it (empty register). It is
recommended this be set to zero fill to prevent errors.
Parameter mapping Register Mapping is the process of assigning data points from wireless
field devices to EtherNet/IP registers. These registers can then be read
by a EtherNet/IP master or client. EtherNet/IP register mapping can be
found by navigating to System Settings → Protocols → Ethernet/IP.
