The Station Manager Software
CPUE05 provides built-in Station Manager support. It accommodates online diagnostic and
supervisory access through either the Station Manager port or via Ethernet. Station
Manager services include:
•
An interactive set of commands for interrogating and controlling the station.
•
Unrestricted access to observe internal statistics, an exception log, and configuration
parameters.
•
Password security for commands that change station parameters or operation.
•
Access to the Station Manager requires a user-provided computer terminal or terminal
emulator.

IP Addressing
The CPUE05 must have a unique IP address that identifies it on the Ethernet network.
The IP Address is assigned using the configuration software, as described in chapter 6. The
IP address is 32 bits long and has a netid part and a hostid part. The format of the IP address
depends on the network class:
Figure 203
Each IP address on a network has:
•
The same class. Each network is a Class A, Class B or Class C network. A Class A network
can support 16,777,214 hosts, Class B: 65,534 hosts, and Class C: 254 hosts.
•
The same netid, which is generally assigned by the Internet authorities.
•
A different hostid, giving it a unique IP address. The hostid is generally assigned by your
local network administrator.
IP addresses are written in “dotted
-
decimal” format as
four decimal integers (0-255)
separated by periods. Each integer represents one byte of the IP address. For example, the
32-bit IP address
00001010 00000000 00000000 00000001
is written as
10.0.0.1
The class of an IP address is indicated by the first decimal integer:
