这些脉冲涉及某个值，通常是能量脉冲计数连接到累积脉冲的RTU的数字输入端。这些脉冲计数器值被发送到主站。在数字输入板上以固定间隔读取脉冲，然后在每个采样周期结束时，读取RTU中的所有脉冲计数值。脉冲计数器值被打上时间戳并被传输到主站，主站将它们存储在数据库中。脉冲计数器值被阻止的脉冲输入不会被扫描或发送到主站。

RTU仅在其数据库中存储脉冲数。主站缩放脉冲计数器值并将其存储在其数据库中供内部使用。然后，与过程相关的值(如能量)通过将脉冲数乘以每个脉冲所代表的值来获得，该值通常称为“每个脉冲的值”

计数器可以在周期读数结束时清零，例如每小时一次，或者只要设备没有重启就永远不清零。为了进行监督，在数据库中存储新的读数之前，执行检查以确定先前存储的值已被传输。如果出现错误情况(例如输入板故障)，计数器值在传输到主站之前将被标记为无效。

These pulses involve a certain value, usually the energy pulse count connected to the digital input of the RTU for accumulating pulses. These pulse counter values are sent to the main station. Read pulses at fixed intervals on the digital input board, and then at the end of each sampling cycle, read all pulse count values in the RTU. The pulse counter values are timestamped and transmitted to the main station, which stores them in the database. Pulse inputs with blocked pulse counter values will not be scanned or sent to the main station.

The RTU only stores the number of pulses in its database. The main station scales the pulse counter value and stores it in its database for internal use. Then, the value related to the process (such as energy) is obtained by multiplying the number of pulses by the value represented by each pulse, which is usually referred to as the “value of each pulse”

The counter can be reset to zero at the end of the cycle reading, for example once an hour, or never reset as long as the device is not restarted. For supervision purposes, before storing new readings in the database, perform checks to ensure that previously stored values have been transferred. If an error occurs (such as input board failure), the counter value will be marked as invalid before being transmitted to the main station.
