RELIANCE 57C332A工控框架
延迟时间-要求输入保持高于（或低于）报警前延迟时间的限制设置跳闸（变高）。这有助于防止因工艺噪声而跳闸的有害报警。
延迟时间-要求输入保持低于（或高于）极限设置加上延迟时间的死区在警报清除（变低）之前。这有助于防止由于工艺噪声而导致的警报意外清除。
回铃-当报警发生时，导致先前确认的报警需要确认（优先级1-4）清除。HI将过程输入与极限设置进行比较并且当进程等于或高于限制设置。这个当进程较少时，报警状态将清除（0）大于极限设置减去死区。
LO将过程输入与极限设置进行比较并且当进程等于或小于限制设置。这个当进程较大时，报警状态将清除（0）大于极限设置加上死区。
HI-DEV比较了流程之间的差异
输入和偏差输入（P-D）与极限设置，并且在以下情况下将触发报警状态高（1）：
（P-D）等于或大于极限设置。这个当（P-D）小于限制设置减去死区。
LO DEV比较了偏差输入和过程输入（D-P）与限制设置，它将触发报警状态高（1）
当（D-P）等于或大于极限时背景当（D-P）为时，报警状态将清除（0）小于极限设置减去死区。
DEV比较了过程输入和偏差输入|P-D|与限制设置，它将触发报警状态高（1）当|P-D|等于或大于极限设置时。当|P-D|小于时，报警状态将清除（0）极限设置减去死区。或将过程输入与范围指针参数引用的范围限制进行比较，并将触发报警状态高（1）当过程等于或大于上限或等于或小于下限时。
当进程小于上限减去死区或大于下限加上死区。通电-在热启动期间，所有报警的处理方式与热启动期间相同：输出初始化在最后一个状态下，所有先前确认的报警都被视为已确认，任何新的报警都将被在第一扫描周期上处理。冷启动时，所有报警输出均初始化为0，所有报警均复位，任何
基于块输入的新报警将在第一个扫描周期内处理。在冷起动期间，报警将由PU启用参数确定启用或禁用。报警状态报警状态可通过Modbus通信或本地仪表链路选项进行报警管理
在远程位置。报警状态在具有Modbus通信的线圈中可用，或相同信息为：
通过LIL通信打包成单个字（报警状态字）。有关详细信息，请参见本文件的网络通信部分。
HI compares the process input with the limit setting and it will trip the alarm status high (1) when the process is equal to or higher than the limit setting. The alarm status will clear (0) when the process is less than the limit setting minus the deadband. LO compares the process input with the limit setting and it will trip the alarm status high (1) when the process is equal to or less than the limit setting. The alarm status will clear (0) when the process is greater than the limit setting plus the deadband. HI DEV compares the difference between the process input and the deviation input (P-D) with the limit setting and it will trip the alarm status high (1) when (P-D) is equal to or greater than the limit setting. The alarm status will clear (0) when (P-D) is less than the limit setting minus the deadband. LO DEV compares the difference between the deviation input and the process input (D-P) with the limit setting and it will trip the alarm status high (1) when (D-P) is equal to or greater than the limit setting. The alarm status will clear (0) when (D-P) is less than the limit setting minus the deadband. DEV compares the absolute difference between the process input and the deviation input |P-D| with the limit setting and it will trip the alarm status high (1) when |P-D| is equal to or greater than the limit setting. The alarm status will clear (0) when |P-D| is less than the limit setting minus the deadband. OR compares the process input with the range limits referenced by the range pointer parameter and will trip the alarm status high (1) when the process is equal to or greater than the high limit or equal to or less than the low limit. The alarm status will clear (0) when the process is less than the high limit minus the deadband or greater than the low limit plus the deadband. POWER UP - During a warm start, all alarms will be handled the same as during a hot start: outputs are initialized at the last state, all previously acknowledged alarms are treated as acknowledged, and any new alarms will be processed on the first scan cycle. On a cold start, all alarm outputs are initialized at 0, all alarms are reset and any new alarms, based on the block inputs, will be processed during the first scan cycle. Also, during a cold start, alarms will be enabled or disabled as determined by the PU ENable parameters. Alarm Status Alarm status is available with Modbus communication or the Local Instrument Link option for alarm management at a remote location. The alarm status is available in coils with Modbus communication or the same information is packed into a single word (Alarm Status Word) with LIL communication. Detailed information can be found in the Network Communications section of this document.
