Term: Definition:
Adapter The adapter interfaces between DeviceNet devices and
ArmorPoint I/O modules. ArmorPoint I/O DeviceNet adapters
include the 1738-ADN12, -ADN18, -ADN18P, and -ADNX.
Auto Catalog Replace The ArmorPoint I/O DeviceNet adapter supports the swapping
of two identical modules connected to the adapter. That is, if a
1738-IB4M12 is in slot 3 and another 1738-IB4M12 is in slot 7,
the two modules can be removed from the ArmorPoint system
and the slot 3 module placed into slot 7, and vice-versa. When
Automatic Device Replacement (ADR) is active, the swapped
modules will be reconfigured to match the previous module in
their new slot. When ADR is not active, the configuration
parameters will not be modified, the swapped modules must
have identical configuration and values for their EDS file
parameters.
Auto Device Replacement
(ADR) This refers to the ADR feature of a ControlLogix System on
DeviceNet. With ADR active, any device on the DeviceNet link
may be removed and replaced with an out-of-the-box
checkmark compliant DeviceNet device. The ADR feature will
result in downloading the values of the configuration
parameters of the EDS file of the removed device to the new
device.
Auto Start Mode A feature that lets the ArmorPoint I/O system get “up and
running” without the prerequisite to configure any of the EDS
parameters for the PointBus
™ or ArmorPoint I/O modules.
Using Auto Start Mode will result in a scan list within the
adapter that stores the modules identity information.
Autobaud A feature in devices (e.g., ArmorPoint I/O modules) on the
DeviceNet network that causes them to listen to
communications on the network and set their own baudrate to
match the network rate.
Backplane The PointBus that consists of ArmorPoint I/O modules
connected to the ArmorPoint DeviceNet adapter.
Baudrate Rate of communications between devices on the DeviceNet
network. Backplane baudrate is used for the 1738-ADN12,
-ADN18, and -ADN18P. Subnet baudrate is used for the
1738-ADNX.
Change of State (COS) DeviceNet communications method in which the adapter
sends data based on detection of any changed value within
the input data. Data is independently received based on a
change of state from the sender. Data in both directions can be
acknowledged or unacknowledged depending on the run-time
configuration of the system.
Commissioning The period in time associated with post startup activities.
Commissioning implies that the system has been validated
and all configuration parameters are correct, all modules are
in good operating condition, and the adapter scanlist is
complete.
ControlFlash™ Utility software you can use to update the adapter’s firmware
with the most current boot and application code.
