为适应工业环境使用，与一般控制装置相比较，PLC机有以下特点：

1. 可靠性高，抗*力强

    工业生产对控制设备的可靠性要求：

①平均故障间隔时间长

②故障修复时间（平均修复时间）短

任何电子设备产生的故障，通常为两种：

     ①偶发性故障。由于外界恶劣环境如电磁干扰、超高温、超低温、过电压、欠电压、振动等引起的故障。这类故障，只要不引起系统部件的损坏，一旦环境条件恢复正常，系统也随之恢复正常。但对PLC而言，受外界影响后，内部存储的信息可能被破坏。

     ②*性故障。由于元器件不可恢复的破坏而引起的故障。

如果能限制偶发性故障的发生条件，如果能使PLC在恶劣环境中不受影响或能把影响的后果限制在zui小范围，使PLC在恶劣条件消失后自动恢复正常，这样就能提高平均故障间隔时间；如果能在PLC上增加一些诊断措施和适当的保护手段，在*性故障出现时，能很快查出故障发生点，并将故障限制在局部，就能降低PLC的平均修复时间。为此，各PLC的生产厂商在硬件和软件方面采取了多种措施，使PLC除了本身具有较强的自诊断能力，能及时给出出错信息，停止运行等待修复外，还使PLC具有了很强的抗*力。
