- PLC"Programmable Logic Controller" A Programmable Logic Controller, PLC, or Programmable Controller is a digital computer used for automation of industrial processes, such as control of machinery on factory assembly lines. Used to synchronize the flow of inputs from (physical) sensors and events with the flow of outputs to actuators and events variables viewed in the Watch Window are saved as a part of the project. This means that the next time you open the project, those variables will be pre-loaded in the watch window. This does not apply to AKD variables, which are not saved with the project.
- While variables may be changed or locked/unlocked (see Force a Variable), parameters may not be. AKD parameters in the Watch Window are read only.
