适用范围：This Part of IEC 61131 specifies requirements and related tests for programmable controllers (PLC) andtheir associated peripherals (for example, programming and debugging tools (PADTs), human-machineinterfaces (HMIs), etc.) which have as their intended use the control and command of machines andindustrial processes.PLCs and their associated peripherals are intended to be used in an industrial environment and may beprovided as open or enclosed equipment. If a PLC or its associated peripherals are intended for use inother environments, then the specific requirements, standards and installation practices for those otherenvironments must be additionally applied to the PLC and its associated peripherals.This standard also applies to any products performing the function of PLCs and/or their associatedperipherals.Equipment covered in this standard is intended for use in overvoltage category II (IEC 60664-1) inlow-voltage installations, where the rated mains supply voltage does not exceed a.c. 1 000 V r.m.s. (50/60Hz), or d.c. 1 500 V. (If PLCs or their associated peripherals are applied in overvoltage category IIIinstallations, then additional analysis will be required to determine the suitability of the equipment for thoseapplications.)
