Terminology
This table defines the terms that are used in this publication.
Acronym | Full Term | Definition |
|---|---|---|
BP | Backplane Power | Power that is generated from module power by the adapter and expansion power, and
supplied to the I/O system through the backplane. |
CIP™ | Common Industrial Protocol | An industrial communication protocol that is used by Logix 5000® based automation
systems on EtherNet/IP™, ControlNet®, and DeviceNet® communication networks. |
CIP Sync™ | Common Industrial Protocol Synchronization | CIP Sync provides the increased control coordination needed for control
applications where absolute time synchronization is vital to achieve real-time
synchronization between distributed intelligent devices and systems. |
CJC | Cold Junction Compensator | A device that is used in thermocouple measurements to help obtain accurate
temperature readings at the hot junction. |
DAC | Digital to Analog Converter | A device converts digital signals into analog signals, enabling seamless
communication between digital devices and analog systems. |
DCE | Data Communications Equipment | A device that facilitates data transmission over a network. |
DTE | Data Terminal Equipment | A device that serves as a communication endpoint in a network. |
HART | Highway Addressable Remote Transducer | A protocol that enables both analog and digital communication over the same
wiring, including device diagnostic and status information. |
HSC | High-speed Counter | A device that is used to count input signals at a rapid rate. Typically
associated with incremental encoders. |
LA | Local Actuator - Power | Local Actuator Power supplied through the RTB. |
MB | Mounting Base | A device that provides data and power connections from the backplane to the
installed module. |
MP | Module Power | Power that is supplied to the adapter and expansion power. |
MSB | Most Significant Bit | The bit that has the largest value in a multi-bit binary number. |
MTO | Motor Torque Off | A motor control function that disables torque generation by removing
torque-producing drive output from the motor. |
NFC | Near Field Communication | A short-range wireless technology that enables communication between two
electronic devices over a distance of 4 cm (1.6 in.) or less. |
ODVA | Open DeviceNet Vendor Association | A nonprofit association of vendors that are established for the promotion of CIP
networks. |
PL | Performance Level | ISO 13849-1 safety rating |
RIUP | Removal and Insertion Under Power | A feature that enables the device to be connected and disconnected from the
system without having to remove power from the system. |
RPI | Requested Packet Interval | Time interval (usually in milliseconds) that users are requesting their data be
exchanged at |
RTB | Removable Terminal Block | A component that is used for wiring field devices to. |
RTD | Resistance Temperature Detector | A type of sensor whose resistances change as its temperature changes. |
SA | Sensor Actuator - Power | Sensor Actuator Power (24V DC nominal) for the field devices. |
SELV | Safety Extra Low Voltage | An electrical system where the voltage level is considered safe under normal or
fault conditions, as defined in the EN and IEC standards. |
SIO | Standard Input/Output | Describes the function of a port on an IO-Link master device. |
SSI | Serial Synchronous Interface | A serial communication standard for transmitting data between a leader device and
a follower device. Typically associated with absolute encoders. |
SSV | Sensor Source Voltage | Voltage that is supplied to a sensor. |
VCL | Voltage Clamp Low | The low threshold for limiting the voltage level. |
XT | Extreme Environment | Modules with XT at the end of their catalog numbers have design considerations
and conformal coating that add a degree of protection for harsh, corrosive gas
environments. |
