安全级别协议的标准通过以太网传输的安全级别协议的主要标准已经使用了15年以上了。定义现代数字化安全系统需求的主要规范包含在以下标准中：国际电工委员会（IEC）61508 电气/电子/可编程安全级别系统的功能性安全，以及IEC 61784-3 工业通讯网络-配置文件 -第3部分：功能性安全现场总线-通用规则及配置文件定义。
第一批数字化安全系统是采用了单独的、自有的通讯总线的专用控制器。这对于实现安全性来说是前进了一步，可是需要为其设计师和最终用户提供额外的硬件、编程软件、许可、以及额外的现场总线。
诸如EtherCAT这种快速的、高效的工业以太网系统的出现使人们有可以使用IEC 61784-3推荐的“黑色通道”方式。同时也给出了另一个重要的建议，即安全数据通道不能超过目标安全完整性等级（SIL）安全级别最大失效概率的1%，安全配置文件是根据SIL的安全级别设计的。这可以让安全协议集合在现场总线系统内部“打开通道”，极大程度上简化了安全系统的硬件和软件。Safety over EtherCAT (FSoE)）协议符合IEC 61748-3标准中的功能安全通讯设备行规（[FSCP 12]）。在FSoE上的大多数EtherCAT功能性安全的设备都是SIL3级别的。
FSoE的趋势
FSoE的发展趋势是接受来自多家供应商的安全逻辑控制器和安全输入/输出（I/O）设备。已有27家公司生产的产品作为FSoE系统的补充。这也是基于众多供应商对EtherCAT的支持，其中包括200家主控制器供应商、105家I/O供应商、以及160家传动设备供应商。
除此以外，具有安全运动功能的伺服传动已经问世，由于运动控制器可以为了安全停止、安全转矩、以及安全位置（请见表格）而直接向传动设备发送安全功能指令，已经使运动控制产品供应商及用户的自动化设计更加高效合理。不仅如此，不再需要给传动设备停止供电， 这一直以来都是争论的焦点，特别是在考虑例如在按下紧急停止按钮之后，一个惯性滑行的飞轮是否真的可以建立最安全的状况。
