模拟输入/输出更改的点列表在下表中,“格式”列中的条目表示可以通过查找第7–72页表7–11:内存映射数据格式中的条目来确定相关数据点的格式。例如,“F1”格式在该表中被描述为一个(16位)无符号值,没有任何小数位数。因此,应以这种方式解释读取的值。该点用于根据其他点中给出的每单位量的1000分重构电压值。用这个点乘以这个点,再除以1000得到伏特。由于某些SCADA系统不读取32位值,因此在标称一次电压可能超过32767伏的情况下,您还可以将VT比率与主设备中的标称二次电压(均为16位)相乘。**该点用于根据其他点中给出的每单位数量的1000次重构功率值。将特定点乘以这个点,然后除以1000得到VA、kW或kvar。在Modbus中,当前按键以格式代码F6报告。为了使该值适合十六位有符号值,在DNP中使用F8,当没有按键时返回ASCII零(49十进制)
Point List For Analog Input/ Output Change In the following table, the entry in the “Format” column indicates that the format of the associated data point can be determined by looking up the entry in Table 7–11: Memory Map Data Formats on page 7–72. For example, an “F1” format is described in that table as a (16-bit) unsigned value without any decimal places. Therefore, the value read should be interpreted in this manner This point is used to reconstruct voltage values from the 1,000ths per-unit quantities given in the other points. Multiply the particular point by this one, and divide by 1000 to get volts. Since some SCADA systems don’t read 32 bit values, you can also multiply the VT ratio and nominal secondary (both of which are 16 bit) in the master in cases where the nominal primary may exceed 32767 volts. ** This point is used to reconstruct power values from the 1,000ths per-unit quantities given in the other points. Multiply the particular point by this one, and divide by 1000 to get VA, kW or kvar. In Modbus, the current keypress is reported with format code F6. In order to fit the value into a sixteen-bit signed value, F8 is used in DNP, with ASCII zero (49 decimal) returned when no key is pressed.
