LWN1902-6开关电源模块
预设开始值您可以预设正负起始值用于计数器。计数操作从起始值开始继续与中的箭头对应直到启用停止或开始值为再次加载。
负起始值最小负启动值为–32768（8000H）。通过预设负起始值，因此可以最多计数32768个脉冲，直到零穿过柜台。
正起始值如果预设了正的起始值，计数器将递增计数
值为+32767（7FFFH），继续值为-32768（8000H）时的计数操作然后在到达从–1过渡到0。
最小正起始值为1。如果您预设此值
值，65535个脉冲将计数为零十字路口为了计数超过32767个脉冲过零，必须计算起始值
根据以下方程式：
起始值=32767–（脉冲数–32768）
例子：将对40000个脉冲进行计数。起始值在正范围内，因为更多必须对32768个脉冲进行计数。技术数据07 KT 93通常，ABB Procontic CS31系统说明第2卷中列出的技术系统数据对所有模块和中央单元。以下列出了其他数据或与系统数据不同的数据。3.5.1一般数据二进制输入数24二进制晶体管输出数量16通过CS31系统总线通过多达744个二进制输入扩展I/O496个二进制输出96个模拟输入通道48个模拟输出通道与二进制输入和输出相比，总共最多31个远程模块，与CS31系统总线接口相比（另请参见图3-5）潜在差异为了避免07 KT 93中央单元和连接到COM1接口的外围设备，提供此设备从开关柜插座（另见接地图3–3中的连接）。
Preset start values
You can preset both positive and negative start values
for the counter.
The counting operation starts at the start value and is
continued in correspondence with the arrows in the
diagram until the enabling is stopped or a start value is
loaded again.
Negative start value
The minimum negative start value is
–32768 (8000H).
By presetting a negative start value it is thus possible
to count a maximum of 32768 pulses up to the zero
crossing of the counter.
Positive start value
If a positive start value is preset, the counter counts up
to the value of +32767 (7FFFH), continues the
counting operation at the value of–32768 (8000H) and
then signals the zero crossing when reaching the
transition from –1 to 0.
The minimum positive start value is 1. If you preset this
value, 65535 pulses will be counted up to the zero
crossing.
In order to count more than 32767 pulses up to the
zero crossing, the start value has to be calculated
according to the following equation:
Start value = 32767 – (number of pulses – 32768)
Example:
40 000 pulses are to be counted.
The start value is in the positive range, because more
than 32768 pulses have to be counted.Technical data 07 KT 93

Potential differences In order to avoid potential differences between the
07 KT 93 central unit and the peripheral device connected to the COM1 interface, this device is supplied
from the switch cabinet socket (see also the earthing
connections in Fig. 3–3).
