high pass filter
A filter that excludes all frequencies below a defined frequency. It allows, or
passes, frequencies above the defined frequency. It is useful for removing low
frequency signal components that would dominate the signal.
low pass filter
A low pass filter excludes frequencies above a defined frequency. It allows, or
passes, frequencies below the defined frequency. It is useful as an anti-aliasing
filter.
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."
