What benefits does IEC 61131-3 offer?

IEC 61131-3 makes controls easier to develop and maintain.
The programming language improves software life cycles, making requirements analysis, design, construction, testing, validation, installation, operation, and maintenance easier.
IEC 61131-3 increases the efficiency of implementing new automation solutions by using readily available control components developed on other projects and by outside developers.
Designers can program complicated systems without spending needless time, money, and effort on software.
Users encounter less errors since data typing helps to prevent them early in development.
