一、支持的通讯协议
基础通讯能力：该脱扣器本身不带原生通讯接口，需选配ABB专用通讯扩展模块实现数据交互
主流支持协议：
Modbus RTU：最常用的工业串行通讯协议，可接入PLC/DCS系统实现远程监控
Profibus DP：适配西门子等主流工业自动化控制系统，支持高速数据传输
部分版本可选配Modbus TCP以太网通讯模块，实现网络化远程管理
二、核心组态参数
1.过载保护（L段）组态参数
电流阈值I1：调节范围0.4In–1.0In，共25档可选
脱扣时间t1：调节范围3s–144s，支持8条反时限曲线选择
热记忆功能：可手动开启/关闭，模拟线缆热积累特性
2.选择性短路保护（S段）组态参数
功能使能：可通过DIP开关手动开启/关闭该段保护
电流阈值I2：调节范围0.6In–10.0In
脱扣时间t2：调节范围0.05s–0.80s，支持定时限t=k、反时限t=k/I²两种曲线
区域选择性联锁：可手动开启/关闭，实现上下级保护精准配合
启动屏蔽功能：可手动开启/关闭，规避电机启动电流误触发保护
