This part of IEC 61131 specifies functional and electromagnetic compatibility requirements and related verification tests for industrial control equipment of the following types: - programmable controllers (PLC); - programmable automation controller (PAC); - remote I/O; - programming and debugging tools (PADTs); - industrial PC (computers) and industrial panel PC; - displays and human-machine Interfaces (HMI) for industrial use; - distributed control system (DCS), and DCS components that are listed here in the scope; - any product where the primary purpose is performing the function of industrial control equipment, including PLC and/or PAC, and/or their associated peripherals which have as their intended use the control and command of machines, automated manufacturing and industrial processes, e.g. discrete, batch and continuous control. In this document "control equipment" is equivalent to "industrial control equipment" as are PLC and PAC.
