Communication Chapter 4
In this example, the NetID is 192.1.1.0 and the HostID is 0.0.0.207.
The relationship between NetID and HostID depends on the IP
address class, the discussion of which is beyond the scope of this
document (the example uses a Class C IP address). Devices on the
same subnet can communicate directly; devices on different subnets
may communication with each other only through a gateway or
router.
The Gateway IP Address defines the address of the gateway or router
on the unit’s subnet that is used to route messages to other subnets for
wide-area networking. Default: 128.1.1.1.
Optional ControlNet Communication
Powermonitor 3000 units with a catalog number ending in -CNT are
equipped with an optional redundant ControlNet port and a native
RS-485 port in a dual-port configuration that allows simultaneous
operation of the ports. You must configure the communication
parameters before you connect the power monitor to a ControlNet
network.
The only configuration parameter is the ControlNet node number
(also called MAC ID). The range of this parameter is 1…99 with a
default of 99. A node number of 0 is typically used as the address of a
ControlNet scanner.
