Glossary
Broadcast
Data transmissions to all address or functions
Bumpless reconfiguration
A reconfiguration in which the real time data connection to the module is not
closed and reopened. Communications are never interrupted and
configuration data is applied to the module immediately. This works best in a
single owner-controller system.
Compatible match
An electronic keying protection mode that requires that the physical module
and the module configured in the software to match according to vendor and
catalog number. In this case, the minor revision of the module must greater
than or equal to that of the configured slot.
Connection
The communication mechanism from the controller to another module in the
control system.
ControlBus
The backplane used by the 1756 chassis.
ControlLogix chassis
Hardware assembly that houses devices such as ControlLogix Hydraulic Servo
modules, ControlLogix controllers and power supplies.
ControlLogix controller
Controller used in the ControlLogix system that uses programmable memory
for storage of data to implement specific functions such as I/O control, logic,
timing and data file manipulation. The ControlLogix controller owns and
communicates with the ControlLogix Hydraulic Servo module to control
hydraulic applications.
ControlLogix power supply
An electrical circuit that filters, conditions and supplies appropriate voltages
for system components and circuitry.
