Network Setup
This section is intended to help ISP or network technicians install the PLC WatchDog. If this section does
not make sense to you, it is strongly advised to request the service of a network technician.
SECURITY NOTE: Ultimately, it is the End User’s responsibility to make sure the PLC WatchDog is
properly placed behind a secured network security system.
Configuring a Modem/Router
If the PLC WatchDog is connected to a modem/router that is configurable, listed below are a few
recommendations to assist with setup. The methods below do not cover every configuration that
is available.
DHCP Reservations
This is the preferred method for installation. A reservation can be an option in the configuration of a
modem/router. It can be set to serve a given MAC address with a certain IP address when it is introduced
to the network. As mentioned above, the MAC address of the PLC WatchDog can be found on a label on
the front of the Red Lion controller.
Once the IP address has been setup for the MAC address, forward incoming requests on ports 21 and 80.
