在选择设备时，首先要选择有较高抗干扰能力的产品，其包括了电磁兼容性（EMC），尤其是抗外部干扰能力，如采用浮地技术、隔离性能好的PLC系统；其次还应了解生产厂给出的抗干扰指标，如共模拟制比、差模拟制比，耐压能力、允许在多大电场强度和多高频率的磁场强度环境中工作；另外是靠考查其在类似工作中的应用实绩。在选择国外进口产品要注意：我国是采用220V高内阻电网制式，而欧美地区是110V低内阻电网。由于我国电网内阻大，零点电位漂移大，地电位变化大，工业企业现场的电磁干扰至少要比欧美地区高4倍以上，对系统抗干扰性能要求更高，在国外能正常工作的PLC产品在国内工业就不一定能可靠运行，这就要在采用国外产品时，按我国的标准（GB/T13926）合理选择。
2综合抗干扰设计
主要考虑来自系统外部的几种如果抑制措施。主要内容包括：对PLC系统及外引线进行屏蔽以防空间辐射电磁干扰；对外引线进行隔离、滤波，特别是原理动力电缆，分层布置，以防通过外引线引入传导电磁干扰；正确设计接地点和接地装置，完善接地系统。另外还必须利用软件手段，进一步提高系统的安全可靠性。
