Sites
A site in an ION Enterprise system contains one or more intelligent devices that
share a common communications link. There are three different types of sites, based
on the type of communications medium each uses. The site types are as follows:

on the type of communications medium each uses. The site types are as follows:
◆
Direct (Serial) Site - a direct-connected RS-232 or RS-485 network
◆
Modem Site - a remote serial site connected by a modem
◆
Ethernet Gateway Site - a gateway that transfers data between an Ethernet
device and an RS-485 chain of connected devices

Devices
Devices refer to intelligent devices (basic energy meters, multi-function
monitoring/analysis/control devices, intelligent relays, etc.) that can be connected
to an ION Enterprise network serially, via Ethernet, or through a gateway.

Serial Devices belong to Direct Sites or Modem Sites, so they communicate using
modem, RS-232, or RS-485 connections. Before these types of devices can be added
to the network, they require the prior configuration of a Direct Site or Modem Site.

Dialout Modems
A Dialout Modem is the modem that a server computer uses to communicate with
a remote modem at a Modem Site.

Connection Schedules
Connection schedules are programmed routines for a server to regularly connect
to and disconnect from Modem Sites and their associated ION (or other) devices.
If so desired, you can also create connection schedules from Direct Sites and
Ethernet Devices / Ethernet Gateway Sites.
