MAC ID
See node address.
master device
A device which controls one or more slave devices. The XM-440 Master Relay
module is a master device.
Node Address
A DeviceNet network can have as many as 64 devices connected to it. Each
device on the network must have a unique node address between 0 and 63.
Node address 63 is the default used by uncommissioned devices. Node
address is sometimes called “MAC ID.”
NVS (Non-Volatile Storage)
NVS is the permanent memory of an XM module. Modules store parameters
and other information in NVS so that they are not lost when the module loses
power (unless Auto Save is disabled). NVS is sometimes called “EEPROM.”
online help
Online help allows you to get help for your program on the computer screen
by pressing F1. The help that appears in the Help window is context sensitive,
which means that the help is related to what you are currently doing in the
program.
Polled
DeviceNet communications method in which module sends data in response
to a poll request from a master device.
Program mode
The XM module is idle. Typically this occurs when the module configuration
settings are being updated with the XM Configuration program. In Program
mode, the signal processing/measurement process is stopped. The status of
the alarms is set to the disarm state to prevent a false alert or danger status.
Run mode
In Run mode, the module collects measurement data and monitors each
measurement device.
