For medium voltage systems it is common to use two or three autoreclose shots, and, for specific applications, four shots. Using four shots, final dead time can be set for a time long enough to allow thunderstorms to stop before definitive final reclose. This scheme prevents unnecessary lockout caused by consecutive transient faults.
Name Contains the name of the controller. You can enter any name you wish
in this field up to a maximum of 16 characters. Spaces between name
segments are not permitted.
Controller device names must be unique across a network
Description Enter a description of the controller up to 32 characters in length
(optional).
ACCNet ID Identifies each controller on an Andover Continuum network by a
unique number between 1 and 190. Each controller must have a unique
ID on its particular network.
IP Address A logical 32-bit address that identifies a TCP/IP host. Each controller
requires a unique IP address. Each address has two parts: a network
ID, which identifies all hosts on the same physical network, and a host
ID, which identifies a host on the network.
Subnet Mask Subnets divide a large network into multiple physical networks
connected with routers. A subnet mask blocks out part of the IP
address so that TCP/IP can distinguish the network ID from the host
ID. When TCP/IP hosts try to communicate, the subnet mask
determines whether the destination host is on a local or remote
network.
To communicate within a local network, computers and controllers
must have the same subnet mask.
Gateway Address The Gateway is the intermediate device on a local network that stores
network IDs of other networks in the enterprise or on the Internet. To
communicate with a host of another network, configure an IP address
for the default Gateway. TCP/IP sends packets for remote networks to
the default gateway (if no other route is configured), which forwards
the packets to other gateways until the packet is delivered to a
gateway connected to the specific destination.
If you are using a proxy server, you must define a default router here.
Probe Time Displays the time, in seconds, between controller probes.
A probe is a message that the device sends out to its controllers to
check their COMM status. Controllers respond to probe messages to let
the device know they are online. When a device does not receive a
response from a controller, it changes the controller's COMM status to
Offline.
Web Server Port The standard port for Web communications. The default setting is 80.
The Web Server Port can be set to any number from 1 to 65,534. If
changed, browser requests must specify the port number in the URL,
for example, http://<IP Address>:<Web Server Port>.
