远程控制威力是无比的。可提升PLC的控制能力、扩大控制地域及提高控制效益。总之，远程控制也已是PLC应用的重要方面。
以上介绍的五大控制，头三个是为了使不同的系统都能实现自动化。信息控制是为了实现信息化，其目的是使自动化能建立在信息化的基础上，实现管理与控制结合，进而做到供、产、销无缝连接，确保自动化效益。
远程控制则是使在信息化基础上的自动化能远程化。既可实现各个角落信息汇总，保证信息完整，为信息的全面使用提供方便；又为自动化的扩展，能从局部的设备级，发展到全局的生产线级，车间级，以至于工厂级、地域级，建立自动化工厂、数字化城市，提供可能。显然，这种大规模、大范围的自动化、信息化，将具有更大威力及得到更大的效益。
