Sites
A site in an WinPM.Net 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:
๎‚‹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
NOTE
You are not required to create a site for an Ethernet Device, unless you intend to use the device as an
Ethernet Gateway Site.
Depending on the site type, devices belonging to a site may be at different physical
locations.
Devices
Devices refer to intelligent devices (basic energy meters, multi-function
monitoring/analysis/control devices, intelligent relays, etc.) that can be connected
to an WinPM.Net 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.
Ethernet Devices are those that are directly connected to an Ethernet network. You
are not required to create a site for an Ethernet Device, unless you intend to use the
device as an Ethernet Gateway Site. Furthermore, you can manually connect and
disconnect your Ethernet Devices from the Management Console.
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 ACCESS (or other)
devices. If so desired, you can also create connection schedules from Direct Sites
and Ethernet Devices/Ethernet Gateway Sites.
