Host Parameters (only PowerFlex 750-Series drives)
Host parameters are used to configure peripherals connected to a PowerFlex
750-Series drive. When using a PowerFlex 7-Class HIM (catalog number
20-HIM-A3/-A5/-C3S/-C5S), Host parameters do not appear. When using a
PowerFlex 750-Series HIM (catalog number 20-HIM-A6/-C6S), Host
parameters appear in the HOST PARAM folder. You can also view Host
parameters with any of the following drive configuration tools:
• Connected Components Workbench software—click the tab for the
option module at the bottom of the window, click the Parameters icon in
the tool bar, and open the Host parameters folder.
• DriveExplorer software—find the option module in the treeview and
open its Parameters folder.
• DriveExecutive software—find the option module in the treeview,
expand the module in the tree, and open its Parameters folder.
I
Idle Action
An idle action determines how the adapter and connected drive act when the
controller is switched out of run mode.
I/O Data
I/O data, sometimes called ‘implicit messages’ or ‘input/output’, is
time-critical data such as a Logic Command and Reference. The terms
‘input’ and ‘output’ are defined from the controller’s point of view. Output
is produced by the controller and consumed by the adapter. Input is
produced by the adapter and consumed by the controller.
IP Addresses
A unique IP address identifies each node on an EtherNet/IP network. An IP
address consists of 32 bits that are divided into four segments of one byte
each. It appears as four decimal integers separated by periods
(xxx.xxx.xxx.xxx). Each ‘xxx’ can have a decimal value from 0 to 255. For
example, an IP address could be 192.168.0.1.
An IP address has two parts: a network ID and a host ID. The class of
network determines the format of the address.
The number of devices on your EtherNet/IP network will vary depending on
the number of bytes that are used for the network address. In many cases
you are given a network with a Class C address, in which the first three
bytes contain the network address (subnet mask = 255.255.255.0). This
