Change of State (COS)
DeviceNet communications method in which the XM module sends data
based on detection of any changed value within the input data (alarm or relay
status).
current configuration
The current configuration is the most recently loaded set of configuration
parameters in the XM module’s memory. When power is cycled, the current
configuration is loaded with either the saved configuration (in EEPROM) or
the factory defaults (if there is no saved configuration). In addition, the current
configuration contains any configuration changes that have been downloaded
to the module since power was applied.
DeviceNet network
A DeviceNet network uses a producer/consumer Controller Area Network
(CAN) to connect devices (for example, XM modules). A DeviceNet network
can support a maximum of 64-devices. Each device is assigned a unique node
address (MAC ID) and transmits data on the network at the same baud rate.
A cable is used to connect devices on the network. It contains both the signal
and power wires. General information about DeviceNet and the DeviceNet
specification are maintained by the Open DeviceNet Vendor’s Association
(ODVA), ODVA is online at http://www.odva.org.

Electronic Data Sheet (EDS) Files
EDS files are simple text files that are used by network configuration tools
such as RSNetWorx for DeviceNet to describe products so that you can easily
commission them on a network. EDS files describe a product device type,
revision, and configurable parameters.
Help window
A window that contains help topics that describe the operation of a program.
These topics may include
• An explanation of a command.
• A description of the controls in a dialog box or property page.
