A typical network will have a DHCP server, a switch (sometimes combined) and several devices connected
to that switch. A ViewSmart 1600+ can normally be added to such a network simply by connecting the
Ethernet port to the switch using an Ethernet patch cable. The ViewSmart 1600+'s default settings will
allow it obtain an IP address from the DHCP server. Once this happens, the ViewSmart 1600+ can be
accessed from computers and other devices on the network. Computers access the ViewSmart 1600+ by
hostname, or by IP address.
If more than one ViewSmart 1600+ is on the network, and if they need to communicate with each other,
it is recommended to use a static IP configuration
that a dynamic address will be changed by the DHCP server. If the IP address is changed, communication
will fail. Static configuration is necessary when using Modbus® TCP master or Mimic mode over TCP/IP.
If accessing the ViewSmart 1600+ from a computer or other device that can resolve its hostname, dynamic
configuration is fine.
