L0130AE-0H控制系統模塊
指揮權的轉移將命令傳輸到計數器所需的時間裝置取決于裝置的配置（n°總線上的單元數）。
在兩個不同的轉移以確保正確操作。
● 第一種可能性每次傳輸后啟動計時器50-100毫秒并在傳輸下一個命令。
● 第二種可能性使用遠程裝置的內部協議（二進制輸入/輸出狀態字）。
該位稱為“數據傳輸狀態”。
數據傳輸狀態=“0”? 正在執行命令
數據傳輸狀態=“1”? 執行完成上述脈沖圖導致計數向上。計數方向可以顛倒交換輸入A和B。
RPI（參考點啟動器）和C之間的關系（零點）。
為了在穿過機器零點，使用輸入RPI和C。輸入A上的脈沖向上計數，輸入b上的脈沖向下數數。取決于DIP的設置開關、上升邊緣、下降邊緣或兩側邊緣觸發計數。當RPI為接通。信號C不得出現兩次或多次RPI的一個期限內。VALID必須打開。它通過雙絞線直接連接到CS 31。這具有以下優點：–減少布線和材料成本。
–中央單元的串行端口保持空閑。
● 存儲在遠程顯示器EEPROM中的信息TCAD由其消息編號從中央單元。
● 從中央單元激活的各種消息每兩秒鐘在屏幕上滾動一次。
● 激活的消息可以通過以下方式取消激活一次一個或全部。
● 消息顯示在16個超級扭曲的兩行上8 mm高的字符。
● 每條消息中可以嵌入兩個變量數據。每個數據最多有6個字符，其中一個是這是標志。
● 蜂鳴器（可編程）可激活或去激活。
● 前面板上有一個按鍵功能。它可以是在用戶程序中用作輸入以確認消息、蜂鳴器等。
● 遠程顯示器TCAD由PC編程基于編程軟件。
NCB是CS31總線的放大器。
它確保放大器功能，而最大安裝3個NCB后，一輛公交車的長度可達2km。NCB的使用是完全透明的，診斷是在設備和中央單元上可用（如果幾乎有一個）不同線路的故障。
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.
