软启动具有的保护 1）外部故障输入保护。瞬停端子用于外加保护装置，如热继电器等。 2）失压保护。软启动器断电且又来电后，无论控制端子处于何种位置，均不会自行启动，以免造成伤害事故。 3）启动时间过长保护。由于软启动器参数设置不当或其原因造成长时间启动不成功软启动器会自行保护。 4）软启动器过热保护。温度升至80±5℃时保护动作，动作时间＜0.1秒；当温度降至55℃，过热保护解除。 5）输入相保护。滞后时间＜3秒。 6）输出缺相保护。滞后时间＜3秒。 7）三相不平衡保护。滞后时间＜3秒，以各相电流偏差大于50%±10%为基准。 8）启动过电流保护。启动时持续大于电机额定工作电流5倍时保护动作。 9）运行过载保护。以电机额定工作电流为基准作反时限热保护。 10）电源电压过低保护。滞后时间：当电源电压低于极限值50%时，保护动作，时间＜0.5秒，否则低于设定值时保护动作，时间＜3秒。 11）电源电压过高保护。当电源电压高于极限值130%时，保护动作，时间＜0.5秒，否则高于设定值时保护动作，时间＜3秒。 12）负载短路保护。滞后时间：＜0.1秒，短路电流为软启动标称电机电流额定值10倍以上。
模块可以连接到CPU的右侧，进一步扩展数字或模拟输入/输出能力。CPU 1212C接受两个，CPU1214C接受八个信号模块.大量不同的数字量和模拟量模块可提供每种任务所需的输入/输出。数字量和模拟量模块在通道数目、电压和电流范围、隔离、诊断和报警功能等方面有所不同。 对于在此列举的所有模块系列，SIPLUS 部件也可应用在扩展温度范围 -25 - +60℃ 以及腐蚀性环境/冷凝环境中。S7-1200 信号板SIMATIC S7-1200集成通讯支持新用户和人员通过增加一个信号板，可以在控制器上增加数字或模拟I/O来满足您的需求。停机时间并保证运行
创新就已成为西门子业务成功的基石以PROFINET为枢纽，基于企业生产管理平台的核心控制，数据的处理能力将得到尽情释放，设备供应商完全可以对橡胶制造工厂进行远程监控和预警；基于大数据、根据数据波动，设备具备自诊断功能，总是在将坏未坏之时发现问题，将其上报给服务方，工程技术人员可在远程完成维修；设备在生产过程中，能够进行生产的自纠正，通过自适应算法进行调整，提高生产的稳定性。借助统一的PROFINET介质，不仅可以帮助客户提高生产水平，而且可以完成企业的精益化管理。与此同时，软控股份也在筹划建设自己的数据中心。未来，通过PROFINET串联，企业的生产管理平台将实现统一的电子数据管理和信息集成，并与PLM、MES、ERP等系统对接，实现全制造环节的互联互通，在生产与企业管理层面实现数字化。畅享数据，展望智能化远景。西门子与软控就是这样通过PROFINET一“线”相连，共同构建无限可能。制造2025刚刚踏上征程，面对智能制造激动人心的未来，软控股份深耕市场，以理性的实践紧扼信息化奔腾并在一年后的收购埋下了伏笔
作为一个上久负盛名的品牌制造业作为zui重要的经济支柱，正在面临着的挑战，例如：如何缩短产品上市时间、提高生产效率、以及大规模的生产如何能够兼顾价格和个性化的产品等。我们凭借创新技术，硬件软件无缝集成，并可基于数据分析进行服务，确保生产过程更加灵活
