MPS022 13100203參數(shù)說明,Schroff卡件
首次安裝模塊時，鑰匙鎖在背板中央導軌。拔出模塊后，鑰匙仍保留在中央導軌中，配置插槽僅接受相同的模塊類型。如果需要更改模塊在鑰匙鎖在中央導軌上后的機架在機架上，鑰匙可以通過向上推來取下，同時將其從導軌上拔下。然后可以將其重新插入模塊和模塊插入機架中所需位置。注意：只有電源可以放置在最左側(cè)機架位置。編程器連接，并行對于并行接口（僅限MS-DOS程序員）編程器連接到帶電纜IC647CBL703的BTM，如圖2所示。
MPS022 13100203參數(shù)說明擴展機架附件BTM連接到擴展機架中的BRM，帶有電纜IC600WDFxxx（其中xxx為長度，單位為英尺）為如圖1所示。狀態(tài)指示模塊頂部的三個綠色LED提供模塊狀態(tài)信息如下所述。
當CPU軟件完成通電配置并且已輪詢（或試圖輪詢）每個系統(tǒng)中的擴展機架。當任何一個這些條件不符合。中間的LED（程序員端口已啟用）是編程器端口激活LED。當編程器和PLC啟動時，該LED閃爍或點亮溝通。當他們不通信時，它關(guān)閉。請注意，此端口不用于Windows程序員和PLC。
底部LED（擴展端口啟用）提供擴展總線的狀態(tài)。該LED為當BTM與通信時閃爍或打開總線接收器模塊通過并行輸入/輸出總線鏈路。當他們不通信時，它關(guān)閉。卸下模塊從機架插槽中卸下模塊時，應遵循以下說明。牢牢抓住電路板的頂部和底部將拇指放在面板正面的板蓋上將蓋子和手指放在塑料夾子上封面的背面。
擠壓蓋背面的機架夾用手指將夾子從機架導軌并用力拉動板將其卸下從背板連接器。
沿卡導軌滑動板并將其卸下從機架上。
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.
