Examples described herein provide for memory access protection in programmable logic devices. In an example, an integrated circuit includes a programmable logic region, control logic, an interconnect, and a memory controller. The control logic is communicatively coupled to the programmable logic region....
Push buttons, limit switches, andphotoelectric sensorsare examples of devices providing a discrete signal. Discrete signals are sent using eithervoltageorcurrent, where a specific range is designated asOnand another asOff. For example, a PLC might use 24 V DC I/O, with values above 22 VDC ...

Method of organizing programmable logic array devices for board testability A system provides for the testing of components which connect to one or more of programmable logic devices (PLDs), each of which is organized in a predetermined manner. Each PLD includes a plurality of programmable logic se...
1、The programmable Logic Controller (PLC)A Programmable Logic Controller, PLC, or Programmable Controller is a small computer used for automation of industrial processes, such as control of machinery on factory assembly lines. Unlike general-purpose computers, the PLC is designed for extended temper...
AN82250 describes implementation of programmable digital logic designs in the PLD portion of Universal Digital Blocks (UDBs) in PSoC 3, PSoC 4, PSoC 5LP, and PSoC 6. Introduction PSoC 3, PSoC 4, PSoC 5LP, and PSoC6 (hereafter referred to as PSoC) are more than just microcon...
Push buttons, limit switches, and photoelectric sensors are examples of devices providing a discrete signal. Discrete signals are sent using either voltage or current, where a specific range is designated as On and another as Off. For example, a PLC might use 24 V DC I/O, with values ...
or actuators or any other devices in the factory. Along a programmed code on its CPU commands uses this data to control and operate external devices on the factory floor , via so called output modules. The modules translate digital information into physical signals or reformat it into specific ...
