DCS系统在工业生产过程的广泛应用，使可靠性、稳定性问题更加突出，也使人们对整个系统要求越来越高。人们希望DCS系统尽量少出故障，又希望DCS系统一旦出现故障，能尽快诊断出故障部位，并尽快修复，使系统重新工作。下面简单介绍故障大体分类及故障诊断的一般方法。
　　一、DCS系统故障的分类
　　为了便于分析、诊断DCS系统故障发生的部位和产生原因，可以把故障大致分为如下几类。
　　1、现场仪表设备故障
　　现场仪表设备包括与生产过程直接联系的各种变送器、各种开关、执行机构、负载等。现场仪表设备发生故障，直接影响DCS系统的控制功能。在目前的DCS控制系统中，这类故障占绝大部分。这类故障一般是由于仪表设备本身的质量和寿命所致。
　　2、系统故障
　　这是影响系统运行的全局性故障。系统故障可分为固定性故障和偶然性故障。这类故障一般比较明显且影响也是局部的，它们主要是由使用不当或使用时间较长，模板内元件老化所致。
　　3、硬件故障
　　这类故障主要指DCS系统中的模板(特别是I/O模板)损坏造成的故障。这类故障一般比较明显且影响也是局部的，它们主要是由使用不当或使用时间较长，模板内元件老化所致。
　　4、软件故障
　　这类故障是软件本身所包含的错误所引起的，软件故障又可分为系统软件故障和应用软件故障。系统软件是DCS系统带来的，若设计考虑不周，在执行中一旦条件满足就会引发故障，造成停机或死机等现象。此类故障并不常见。应用软件是用户自己编定的。在实际工程应用中，由于应用软件工作复杂，工作量大，因此软件错误几乎难以避免，这就要求在DCS系统调试及试运行中十分认真，及时发现并解决。
　　5、操作、使用不当造成故障
　　在实际运行操作中，有时会出现DCS系统某功能不能使用或某控制不封不能正常工作，但实际上DCS系统并没有毛病，而是操作人员操作不熟练或操作错误所引起的。这对于初次使用DCS系统的操作工较为常见。
