V1.3规范拓宽了国际SERCOS实时标准的功能和应用范围，同时考虑了机器和工厂建设的新趋势。扩展与现有规范完全兼容，以确保高水平的标准化和来自不同制造商的设备的最佳互操作性。
在电子驱动器领先之后，液压和气动性越来越多地向数字控制模块转向。这会增加灵活性，并将先前通过机械手段解决的任务转移到软件解决方案。SERCOS组织认识到这一趋势的重要性，并扩展了现有的SERCOS驱动器型材，以便现在支持电动，液压和气动驱动器。
Two new profiles have been added to the Sercos specification. The energy profile defines parameters and commands for the reduction of the energy consumption in a uniform and vendor-independent manner. An encoder profile makes the interface of absolute and incremental encoders available to all devices on a Sercos network.
在协议级别指定以下新服务：过采样和时间戳。过采样过程允许采集和传输等距值快于配置的总线或连接周期。这增加了在极其关键的应用程序（例如激光应用）中的过程控制复杂性，因为它允许收集更多数据并以更快的速度传送命令值。测量方法直接集成到协议中，从而使得可以在不同的制造商中和独立于产品中访问这些机制。
In addition, the specification defines a time-stamping procedure for the event-triggered acquisition of values with corresponding time stamps, as well as the time-triggered activation of command values. This function is event-controlled, promptly transmitting defined events such as certain measurement values to the controller and switching outputs independently from the clock cycle. This increases process stability in complex solutions such as those needed in semiconductor or solar manufacturing.
规范更新由安装指南完成，该指南指定具有铜线和光纤的电缆，每个都考虑IP20和IP65 / 67保护等级。
