A program including configuration data, symbols, and documentation.
The arrangement and interconnection of hardware components within a system and the hardware and software parameters that determine the operating characteristics of the system.
Automates industrial processes (also known as programmable logic controller or programmable controller).
(digital input/output) An individual circuit connection at the electronic module that corresponds directly to a data table bit. The data table bit holds the value of the signal at the I/O circuit. It gives the control logic digital access to I/O values.
An electronic communication bus between expansion I/O modules and a controller.
A programming unit that has 1 input and returns 1 immediate result. However, unlike FBs, it is directly called with its name (as opposed to through an instance), has no persistent state from one call to the next and can be used as an operand in other programming expressions.
Examples: boolean (AND) operators, calculations, conversions (BYTE_TO_INT)
Rectangular connector for electrical signals with frequencies below 3 MHz, complying with IEC 60807-2.
(input/output)
A standard type of 8-pin connector for network cables defined for Ethernet.
(terminal block) The component that mounts in an electronic module and provides electrical connections between the controller and the field devices.
