L0130AE-0H控制系统模块
指挥权的转移将命令传输到计数器所需的时间装置取决于装置的配置（n°总线上的单元数）。
在两个不同的转移以确保正确操作。
● 第一种可能性每次传输后启动计时器50-100毫秒并在传输下一个命令。
● 第二种可能性使用远程装置的内部协议（二进制输入/输出状态字）。
该位称为“数据传输状态”。
数据传输状态=“0”➟ 正在执行命令
数据传输状态=“1”➟ 执行完成上述脉冲图导致计数向上。计数方向可以颠倒交换输入A和B。
RPI（参考点启动器）和C之间的关系（零点）。
为了在穿过机器零点，使用输入RPI和C。输入A上的脉冲向上计数，输入b上的脉冲向下数数。取决于DIP的设置开关、上升边缘、下降边缘或两侧边缘触发计数。当RPI为接通。信号C不得出现两次或多次RPI的一个期限内。VALID必须打开。它通过双绞线直接连接到CS 31。这具有以下优点：–减少布线和材料成本。
–中央单元的串行端口保持空闲。
● 存储在远程显示器EEPROM中的信息TCAD由其消息编号从中央单元。
● 从中央单元激活的各种消息每两秒钟在屏幕上滚动一次。
● 激活的消息可以通过以下方式取消激活一次一个或全部。
● 消息显示在16个超级扭曲的两行上8 mm高的字符。
● 每条消息中可以嵌入两个变量数据。每个数据最多有6个字符，其中一个是这是标志。
● 蜂鸣器（可编程）可激活或去激活。
● 前面板上有一个按键功能。它可以是在用户程序中用作输入以确认消息、蜂鸣器等。
● 远程显示器TCAD由PC编程基于编程软件。
NCB是CS31总线的放大器。
它确保放大器功能，而最大安装3个NCB后，一辆公交车的长度可达2km。NCB的使用是完全透明的，诊断是在设备和中央单元上可用（如果几乎有一个）不同线路的故障。
Transfer of command
The time required to transfer commands to the counter
unit depends upon the configuration of the installation (n°
of units on the bus).
It is necessary to have a short delay between two different
transfert to ensure correct operation.
● First possibility
Start a timer for 50-100 milliseconds after each transfert
and wait until the time is elapsed before transfering the
next command.
● Second possibility
Use the internal protocol of the remote unit (Bit 0 of the
binary input/output status word).
This bit is called the "Data transfer status".
Data transfert status = "0" ➟ Executing command
Data transfert status = "1" ➟ Executing complete The above shown pulse diagram results in counting
upwards. The counting direction can be reversed by
interchanging inputs A and B.
Relationship between RPI (reference point initiator) and C
(zero point).
In order to reset the counter to 0 when crossing the
machine zero point, the inputs RPI and C are used.mpulses on input A count upwards,impulses on input b
count downwards.Depending on the setting of the DIP
switches, rising edges, falling edges or both edges trigger
counting.The falling edge of C resets the counter to 0 while RPI is
ON. The signal C must not occur twice or more times
within one period of RPI.
The VALID must be ON.It is directly connected to the CS 31 by a twisted pair. This
allows the following advantages :
– reduction of the wiring and material costs.
– the serial port of central unit remains free.
● The messages stored in EEPROM in the remote display
TCAD are called by their message number from the
central unit.
● The various messages activated from the central unit
are scrolled on the screen every two seconds.
● The activated messages can be desactivated one by
one or all at once.
● The message is displayed on 2 lines of 16 supertwist
8 mm high characters.
● Two variable datas can be embedded in each message. Each data has a maximum of 6 characters, one of
which is for the sign.
● A buzzer (programmable) can be activated or
desactivated.
● A key function is available on the front plate. It can be
used in the user program as an input to acknowledge a
message, the buzzer, etc.
● The remote display TCAD is programmed with a PC
based programming software.The NCB is an amplifier for CS31 bus.
It ensures a amplifier function whereas the maximum
lenght on one bus can reached upto 2km with the installation of 3 NCB.
The use of NCB is totally transparent and a diagnosis is
available on the unit and on the central unit if almost one
of the different lines is faulty.
