为故障跳闸涉及的每个断路器提供保护跳闸功能块。它提供可设置的脉冲延长，以确保足够长的跳闸脉冲，以及正确配合自动重合闸功能所需的所有功能。

跳闸功能块还包括一个可设置的门锁功能，用于演化故障和断路器锁定。跳闸矩阵逻辑TMAGGIO跳闹矩阵逻辑TM AGGIO功能用于将跳闸信号和其他逻辑输出信号路由至IED上的不同输出触点。

TMAGGIO输出信号和物理输出允许用户根据具体应用需求将信号调整为物理跳闸输出。固定信号功能块固定信号功能（FXDSIGN)生成许多可用于IED配置的预设（固定)信号，用于强制其他功能块中未使用的输入达到某一水平/值，或用于创建某些逻辑。12.监测测量CVMMXN、CMMXU、VNMMXU和VMMXU，CMSQ和VMSQ。

测量功能用于从IED获取在线信息。这些服务值可以在本地HMI和变电站自动化系统上显示关于以下方面的在线信息:·测量的电压、电流、频率、有功、无功和视在功率和功率因数·一次和二次相量·正序、负序和零序电流和电压mA，输入电流·脉冲计数器mA输入信号监控功能的主要目的是测量和处理来自不同测量传感器的信号。

过程控制中使用的许多设备将频率、温度和直流电池电压等各种参数表示为低电流值，通常在4-20 mA或0-20 mA范围内。报警限可以设置并用作触发器，例如生成跳闸或报警信号。该功能要求IED配备mA输入模块。

A protective trip block is provided for each circuit breaker involved in a fault trip. It offers a configurable pulse extension to ensure a sufficiently long trip pulse, as well as all the functions required to properly match the automatic reclosing function.

The trip function block also includes a configurable door lock function for evolutionary failure and circuit breaker locking. Tripping Matrix logic TMAGGIO Tripping Matrix logic TMAGGIO function is used to route tripping signals and other logic output signals to different output contacts on the IED.

The TMAGGIO output signal and physical output allow the user to adjust the signal to the physical trip output according to the specific application requirements. The Fixed Signal function (FXDSIGN) generates a number of preset (fixed) signals that can be used for IED configuration, to force unused inputs in other function blocks to a certain level/value, or to create certain logic. 12. Monitor and measure CVMMXN, CMMXU, VNMMXU and VMMXU, CMSQ and VMSQ.

The measurement function is used to obtain online information from the IED. These service values can be displayed online on local HMI and substation automation systems about :· Measured voltage, current, frequency, active power, reactive power and apparent power and power factor · Primary and secondary phasors · positive, negative and zero sequence current and voltage mA, Input current · Pulse counter mA The main purpose of the input signal monitoring function is to measure and process signals from different measurement sensors.

Many devices used in process control represent various parameters such as frequency, temperature, and DC battery voltage as low current values, typically in the range of 4-20 mA or 0-20 mA. Alarm limits can be set and used as triggers, such as to generate tripping or alarm signals. This function requires the IED to be equipped with an mA input module.
