在尽管PLC的运行是安全、可靠的，作为一个系统来说，稳定可靠仍然是不可忽视的问题.系统安全设计要充分利用PLC的特点，使PLC的运行能真正达到安全、可靠。
(1)硬件保护。主要包括：联锁保护、限位保护和急停保护等。
(2)软件保护。主要包括：联锁保护、限位保护、限时保护和自检保护等。PLC是利用存储程序进行控制，用存储的程序进行安装保护，也可以使其只执行正确的操作，而拒绝错误的命令。软件保护主要利用自检信息及时发现隐患，清除故障;也可针对工程的特点，自编诊断程序而排除故障，以确保PLC可靠、稳定、安全运行。
PLC控制系统的可靠性，其主要因素还是要做好后期的维护管理工作，维护设备主要部位：供电电源，外部环境、安装状态、电源(Ps)、中央处理单元(CPU)、信号模板(SM)及寿命元件输人、输出中间继电器等外围设备等。
