网络是DCS的基础，网络的性能直接决定着DCS的性能，同时，网络通信的安全也日益成为DCS是否安全可靠的zui大问题。随着信息化的日益深入普及，信息安全的问题凸现，也必将成为影响DCS技术进一步发展和更广泛应用的制约因素。无线通信技术的广泛应用更给通信安全提出了迫切的要求。当务之急是尽快出台一系列有关工业通信的安全标准，结合已有的IT信息安全标准，逐步形成适用于DCS的通信安全和信息安全体系，在DCS系统中逐步完善通信和信息的安全保障功能。
通过“十一五”的努力，我国自主知识产权的DCS已经开始进入大型、综合、成套、关键的应用领域，如千万吨级大型炼油装置成套控制、百万千瓦级超(超)临界火电机组成套控制、百万千瓦级核电机组成套控制等。在上述大型项目的示范与带动下，国产DCS的*进一步提高，国内DCS厂家的经营规模进一步扩大，实力进一步增强。与国外DCS*相比，国内厂家的经营规模还有待提高，系统的功能性还需要进一步提升，特别是成套系统供货能力、整体解决方案(TotalSolution)提供能力、高可靠性、高安全性控制系统的设计制造能力和新产品、新技术的创新能力等方面，还需要有一个大幅度的提高。
