I/O channels that connect to analog I/O devices. Analog channels use varying voltage or current signals.
analog input device
A device that provides a variable current or voltage, such as 4 to 20 milliamps or 0 to 10 volts, representing a condition in a machine or process. An analog input device provides its signal to an analog input signal channel.
analog output device
A device that is provided a variable current or voltage, such as 4 to 20 milliamps or 0 to 10 volts, representing a condition in a machine or process. An analog output device receives its signal from an analog output signal channel.
Part of the global memory of a PLC that incudes binary bits that are available for use by any program block.
code work memory
A section of the work memory that contains parts of the PLC program code.
Modules that allow a PLC to communication with other devices through one or more communication ports on the module.
Central Processing Unit. The brains of the PLC. The CPU stores and scans the user program and stores data needed by the user program and other devices and systems.
DBs. Each DB is an organized set of data in a Siemens PLC program that is used by one or more program blocks. An instance DB stores data use by one program block. A global data block contains data that is available to any program block.
data work memory
A section of the work memory that contains parts of the data blocks and technology objects.
Data Block. An organized set of data in a Siemens PLC program that is used by one or more program blocks. An instance DB stores data use by one program block. A global data block contains data that is available to any program block.
Direct Current. Current that flows in one direction.
A 35 millimeter mounting rail for control components and related devices.
An industrial network used for distributed control communication.
A software or hardware security barrier designed to limit access to a system to authorized personnel or systems.
Gigabyte. Approximately 1 billion bytes. Each byte is 8 consecutive bits.
Memory areas such as image tables and bit memory that are accessible to all program blocks in the user program.
Human machine interface. A device or system that displays machine or process information and provides a means for entering control information.
human machine interface
HMI. A device or system that displays machine or process information and provides a means for entering control information.
Input/Output. Refers to a device, channel, or module involved with PLC inputs and/or output
A standard of the International Electrotechical Commission that provides common approaches and concepts for PLCs.
Tables in a PLC CPU memory that store the most recent input and output status conditions. A binary 1 represents an on condition and a binary 0 represents and off condition.
A device that provides pulses to indicate changes in position.
A type of Ethernet local area network that is widely used for computer and control system communication in factories and other industrial environments.

Non-volatile storage for the user program, program data, and configuration information.
Temporary memory used during the processing of a code block.
Modbus remote terminal unit. A serial communication protocol used to connect a master device, often a PLC or industrial computer, to slave devices. The master device controls the communication of slave devices.
Used to describe a type of memory that does not require continual application of power to prevent data loss.
Proportional-integral-derivative control. One of the most common types of process control. PID control adjusts system outputs by reacting to three values, one that is proportional to an error, one that represents the error over time, and one that represents the rate of change of the error.
PROFIBUS DP is an open standard fieldbus of PROFIBUS & PROFINET International (PI) that is widely used for master-slave control communications in factory automation.
The open Industrial Ethernet standard of PROFIBUS & PROFINET International (PI), and the leading Industrial Ethernet standard world-wide.
The most widely-used form of PROFINET. PROFINET IO extends the benefits of standardized, Ethernet communication to distributed field devices.
PROFINET isochronous real-time. The highest of three simultaneous performance levels of PROFINET IO communication. PROFINET IRT communication is designed to handle the most time-sensitive motion control applications.
A grouping of PLC instructions. A Siemens PLC can have three types of program blocks: organization blocks (OBs), function blocks (FBs), and functions (FCs).
PID control. One of the most common types of process control. PID control adjusts system outputs by reacting to three values, one that is proportional to an error, one that represents the error over time, and one that represents the rate of change of the error.
A two-channel incremental encoder. By comparing the phasing of the pulses received from both channels, a controller can determine the direction of motion.
