9.7 NET network
9.7 NET network
The NET functionality via Ethernet was created in order to simplify communications
between easyE4 base devices while simultaneously ensuring that it would be possible
to import existing easy800 projects.
A NET group can be made up of up to eight easyE4 base devices. Within the group, the
easyE4 base devices can communicate with each other. If, however, you want devices
to be able to communicate across groups, you will need to use a coordinator device
that allows the easyE4 base devices from the various groups to communicate with
each other via Modbus.
Ten NET groups (groups 1 through 10) can be run on a single Ethernet network at one
time (this is the equivalent of 80 easyE4 base devices).
