MPS022 13100203参数说明,Schroff卡件
首次安装模块时，钥匙锁在背板中央导轨。拔出模块后，钥匙仍保留在中央导轨中，配置插槽仅接受相同的模块类型。如果需要更改模块在钥匙锁在中央导轨上后的机架在机架上，钥匙可以通过向上推来取下，同时将其从导轨上拔下。然后可以将其重新插入模块和模块插入机架中所需位置。注意：只有电源可以放置在最左侧机架位置。编程器连接，并行对于并行接口（仅限MS-DOS程序员）编程器连接到带电缆IC647CBL703的BTM，如图2所示。
MPS022 13100203参数说明扩展机架附件BTM连接到扩展机架中的BRM，带有电缆IC600WDFxxx（其中xxx为长度，单位为英尺）为如图1所示。状态指示模块顶部的三个绿色LED提供模块状态信息如下所述。
当CPU软件完成通电配置并且已轮询（或试图轮询）每个系统中的扩展机架。当任何一个这些条件不符合。中间的LED（程序员端口已启用）是编程器端口激活LED。当编程器和PLC启动时，该LED闪烁或点亮沟通。当他们不通信时，它关闭。请注意，此端口不用于Windows程序员和PLC。
底部LED（扩展端口启用）提供扩展总线的状态。该LED为当BTM与通信时闪烁或打开总线接收器模块通过并行输入/输出总线链路。当他们不通信时，它关闭。卸下模块从机架插槽中卸下模块时，应遵循以下说明。牢牢抓住电路板的顶部和底部将拇指放在面板正面的板盖上将盖子和手指放在塑料夹子上封面的背面。
挤压盖背面的机架夹用手指将夹子从机架导轨并用力拉动板将其卸下从背板连接器。
沿卡导轨滑动板并将其卸下从机架上。
When the module is first installed, the key latches onto
the backplane center rail. When the module is extracted, the key remains in the center rail, configuring
the slot to accept only identical module types.
If it is necessary to change the module location in the
rack after the key has been latched onto the center rail
of the rack, the key can be removed by pushing it upward to unhook the latch while pulling it off the rail.
It may then be reinserted onto the module and the
module inserted into the rack in the desired location.
Note: Only the power supply can be placed in the
leftmost rack position.
Programmer Connection, Parallel
For a parallel interface (MS-DOS programmer only), the
programmer is connected to the top connector of the
BTM with cable IC647CBL703 as shown in Figure 2.
Expansion Rack Attachment
The BTM is attached to BRMs in expansion racks with
cable IC600WDFxxx (where xxx is length in feet) as
shown in Figure 1.Status Indications
Three green LEDs at top of module provide module
status information as described below.
The top LED (MODULE OK) LED is ON when the
CPU software completes its power-up configuration
of the BTM, and has polled (or attempted to poll) each
expansion rack in the system. It is OFF when any of
these conditions are not met.
The middle LED (Programmer Port Enabled) is the
Programmer Port Active LED. This LED is either blinking or ON when the programmer and the PLC are
communicating. It is OFF when they are not communicating. Note that this port is not used in communications between the Windows programmer and the
PLC.
The bottom LED (Expansion Port Enabled) provides
the status of the expansion bus. This LED is either
blinking or ON when the BTM is communicating with
the Bus Receiver Modules connected to it through the
parallel I/O bus link. It is OFF when they are not communicating.Removing a Module
The instructions below should be followed when removing a module from its slot in a rack.
Grasp the board firmly at the top and bottom of
the board cover with your thumbs on the front of
the cover and your fingers on the plastic clips on
the back of the cover.
Squeeze the rack clips on the back of the cover
with your fingers to disengage the clip from the
rack rail and pull the board firmly to remove it
from the backplane connector.
Slide the board along the card guide and remove it
from the rack.
