Term: Definition:
Adapter POINT I/O DeviceNet adapter (1734-ADN and 1734-ADNX).
Auto Catalog Replace The POINT I/O DeviceNet adapter supports the swapping of
two identical modules connected to the adapter. I.e., if a
1734-IB4 is in slot 3 and another 1734-IB4 is in slot 7, the two
modules can be removed from the POINT system and the slot 3
module placed into slot 7, and vice-versa. When 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 Replace 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 POINT I/O system get “up and running”
without the prerequisite to configure any of the EDS
parameters for the POINTBus
™ or POINT I/O modules. Using
Auto Start Mode will result in a scan list within the adapter
which stores the modules identity information.
Autobaud Feature in devices (e.g. POINT 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 POINT I/O modules connected to
the 1734-ADN(X) adapter.
Baudrate Rate of communications between devices on the DeviceNet
network. Backplane baudrate is used for the 1734-ADN.
Subnet baudrate is used for the 1734-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
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.
