初始Codesys与ST-1.3.4Codesys的trace示波器跟踪功能
<p style="margin-top: 0px; margin-bottom: 15px; color: rgb(85, 85, 85); font-family: "Microsoft Yahei", "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 15px; text-indent: 30px; text-wrap: wrap;">Codesys平台支持trace跟踪功能，trace实际上就抓数据，显示波形的用途。我们在调试的时候，可以使用波形来协助我们分析程序逻辑，分析设备运行状态。</p><p style="margin-top: 0px; margin-bottom: 15px; color: rgb(85, 85, 85); font-family: "Microsoft Yahei", "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 15px; text-indent: 30px; text-wrap: wrap;"><br/></p><p style="margin-top: 0px; margin-bottom: 15px; color: rgb(85, 85, 85); font-family: "Microsoft Yahei", "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 15px; text-indent: 30px; text-wrap: wrap;"><br/></p><p><img src="/upload/image/20230917/1694911094770218.png" alt="" class="wp-image-3545" style="height: auto; vertical-align: middle; border: 0px; margin: 0px auto; display: block;"/>添加trace</p><p style="margin-top: 0px; margin-bottom: 15px; color: rgb(85, 85, 85); font-family: "Microsoft Yahei", "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 15px; text-indent: 30px; text-wrap: wrap;"><br/></p><p style="margin-top: 0px; margin-bottom: 15px; color: rgb(85, 85, 85); font-family: "Microsoft Yahei", "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 15px; text-indent: 30px; text-wrap: wrap;"><br/></p><p style="margin-top: 0px; margin-bottom: 15px; color: rgb(85, 85, 85); font-family: "Microsoft Yahei", "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 15px; text-indent: 30px; text-wrap: wrap;">首先鼠标放到application上面，然后右击弹出如图上选择框。选择添加对象，然后选择跟踪。这里跟踪需要说明的是名称需要是英文的，不然会报错。</p><p style="margin-top: 0px; margin-bottom: 15px; color: rgb(85, 85, 85); font-family: "Microsoft Yahei", "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 15px; text-indent: 30px; text-wrap: wrap;"><br/></p><p style="margin-top: 0px; margin-bottom: 15px; color: rgb(85, 85, 85); font-family: "Microsoft Yahei", "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 15px; text-indent: 30px; text-wrap: wrap;"><br/></p><p><img src="/upload/image/20230917/1694911094872014.png" alt="" class="wp-image-3546" style="height: auto; vertical-align: middle; border: 0px; margin: 0px auto; display: block;"/>添加trace</p><p style="margin-top: 0px; margin-bottom: 15px; color: rgb(85, 85, 85); font-family: "Microsoft Yahei", "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 15px; text-indent: 30px; text-wrap: wrap;"><br/></p><p style="margin-top: 0px; margin-bottom: 15px; color: rgb(85, 85, 85); font-family: "Microsoft Yahei", "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 15px; text-indent: 30px; text-wrap: wrap;"><br/></p><p style="margin-top: 0px; margin-bottom: 15px; color: rgb(85, 85, 85); font-family: "Microsoft Yahei", "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 15px; text-indent: 30px; text-wrap: wrap;">写好名称后，点击确定。</p><p style="margin-top: 0px; margin-bottom: 15px; color: rgb(85, 85, 85); font-family: "Microsoft Yahei", "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 15px; text-indent: 30px; text-wrap: wrap;"><br/></p><p style="margin-top: 0px; margin-bottom: 15px; color: rgb(85, 85, 85); font-family: "Microsoft Yahei", "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 15px; text-indent: 30px; text-wrap: wrap;"><br/></p><p><img src="/upload/image/20230917/1694911095876376.png" alt="" class="wp-image-3547" style="height: auto; vertical-align: middle; border: 0px; margin: 0px auto; display: block;"/>添加配置</p><p style="margin-top: 0px; margin-bottom: 15px; color: rgb(85, 85, 85); font-family: "Microsoft Yahei", "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 15px; text-indent: 30px; text-wrap: wrap;"><br/></p><p style="margin-top: 0px; margin-bottom: 15px; color: rgb(85, 85, 85); font-family: "Microsoft Yahei", "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 15px; text-indent: 30px; text-wrap: wrap;"><br/></p><p style="margin-top: 0px; margin-bottom: 15px; color: rgb(85, 85, 85); font-family: "Microsoft Yahei", "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 15px; text-indent: 30px; text-wrap: wrap;">咱们这里需要先配置一下trace，配置到Maintask任务下，这个配置的意思就是trace跟踪中数据更新的时间按照配置的任务的扫描周期运行，每个扫描周期更新一次采样数据。</p><p style="margin-top: 0px; margin-bottom: 15px; color: rgb(85, 85, 85); font-family: "Microsoft Yahei", "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 15px; text-indent: 30px; text-wrap: wrap;"><br/></p><p style="margin-top: 0px; margin-bottom: 15px; color: rgb(85, 85, 85); font-family: "Microsoft Yahei", "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 15px; text-indent: 30px; text-wrap: wrap;"><br/></p><p style="margin-top: 0px; margin-bottom: 15px; color: rgb(85, 85, 85); font-family: "Microsoft Yahei", "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 15px; text-indent: 30px; text-wrap: wrap;">配置完成之后，我们还需要为这个跟踪添加监控的数据变量，这里要求-必须是英文的！否则会报错。</p><p style="margin-top: 0px; margin-bottom: 15px; color: rgb(85, 85, 85); font-family: "Microsoft Yahei", "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 15px; text-indent: 30px; text-wrap: wrap;"><br/></p><p style="margin-top: 0px; margin-bottom: 15px; color: rgb(85, 85, 85); font-family: "Microsoft Yahei", "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 15px; text-indent: 30px; text-wrap: wrap;"><br/></p><p style="margin-top: 0px; margin-bottom: 15px; color: rgb(85, 85, 85); font-family: "Microsoft Yahei", "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 15px; text-indent: 30px; text-wrap: wrap;">有了仿真以及trace抓曲线的功能之后，我们就可以很方便的调试程序了。即使我们没有硬件设施，我们也能学习ST编程相关的知识。下一个示例程序中，我们将给大家分享trace波形分析以及仿真的具体用法，敬请期待！</p><p><br/></p>
