GE IC660ELB912 μGENI 網(wǎng)絡(luò)接口板?
IC660ELB912 是來(lái)自 GE Fanuc 的 μGENI 網(wǎng)絡(luò)接口板。它被設(shè)計(jì)為用戶微處理器系統(tǒng)中的子板。用戶可以將 μGENI 和主板連接到任何能夠讀取和寫(xiě)入 μGENI 上的通用共享 RAM 的 CPU 類(lèi)型設(shè)備中。該設(shè)備稱(chēng)為主機(jī)。?
盡管 RAM 接口針對(duì) IBM 個(gè)人計(jì)算機(jī)總線進(jìn)行了優(yōu)化，但它很容易適應(yīng)各種其他 CPU 類(lèi)型。 由于它處理主機(jī)和 Genius I/O 總線之間的所有數(shù)據(jù)傳輸，μGENI 有效地釋放了主機(jī)。這允許主機(jī)控制遠(yuǎn)程 I/O。它通過(guò)使用 Genius I/O 的特性來(lái)實(shí)現(xiàn)這一點(diǎn)，例如高可靠性和抗噪性。此外，主機(jī)可以使用 Genius LAN 的通信功能與其他主機(jī)進(jìn)行通信。
從某種意義上說(shuō)，μGENI 是一個(gè)通用控制器，為 30 多個(gè)其他總線設(shè)備維護(hù)初始化任務(wù)和管理故障。每個(gè)設(shè)備控制一個(gè)I/O，μGENI保持每個(gè)設(shè)備的更新圖像。它還能夠通過(guò)使用全局?jǐn)?shù)據(jù)、數(shù)據(jù)報(bào)和定向控制數(shù)據(jù)消息與其他控制器進(jìn)行通信。所述μGENI有一系列在其單一的印刷電路板復(fù)雜的部件。
它使用 6303 串行接口微處理器將消息寫(xiě)入 MIT 芯片。該芯片管理與總線的硬件接口并提供支持功能。例如，它處理錯(cuò)誤檢查、LED 驅(qū)動(dòng)器和定時(shí)器功能。發(fā)送/接收電路與 MIT 和總線發(fā)送和接收信號(hào)密切配合。
該μGENI采用雙口RAM交換數(shù)據(jù)。這是在 6303 微處理器和管理器微處理器 - 64180 之間完成的。由于兩個(gè)處理器運(yùn)行兩個(gè)獨(dú)立的系統(tǒng)，雙端口 RAM 確保它們都具有平等的訪問(wèn)權(quán)限。這由 GAL 控制，以逐字節(jié)為基礎(chǔ)向任一處理器提供內(nèi)存。64180 還有一個(gè)單獨(dú)的 8Kb RAM 供其專(zhuān)用。
用戶應(yīng)使用墊片將μGENI安裝到主板上。這是通過(guò)在主板的四個(gè)角孔中放置螺釘、支架或塑料 PCB 支架來(lái)完成的。請(qǐng)勿在板上使用任何粘合劑產(chǎn)品。
重要的是μGENI板的安裝方式不會(huì)阻礙整個(gè)板的氣流。用戶應(yīng)注意不要將其安裝在主板上任何其他板或組件的 1/8 英范圍內(nèi)。
μGENI板需要一個(gè) 5V 直流電源來(lái)操作邏輯電源。
he IC660ELB912 is a μGENI Network Interface Board from GE Fanuc. It is designed to be a daughterboard in a user’s microprocessor system. Users can interface the μGENI and the motherboard in any CPU-type device capable of reading and writing to the general-purpose shared RAM on the μGENI. This device is known as the host.??
Although the RAM interface is optimized for the IBM personal–computer bus, it is easy to adapt to various other CPU types. As it handles all data transfers between the host and the Genius I/O bus, the μGENI effectively frees up the host. This allows the host to control remote I/O. It does this by using the features of the Genius I/O, such as high reliability and noise immunity. Furthermore, the host can use the communication features of the Genius LAN to communicate with other hosts.
In a sense, the μGENI is a general-purpose controller, maintaining initialization tasks and managing faults for over 30 other bus devices. Each device controls an I/O and the μGENI keeps updated images of each one. It is also capable of communicating with other controllers through the use of Global Data, datagrams and Directed Control Data messages.The μGENI has a range of intricate components on its single-printed circuit board.
It uses a 6303-serial interface microprocessor to write messages to the MIT chip. This chip manages the hardware interface to the bus and provides support functions. For example, it handles error checking, LED drivers and a timer function. A transmit/receive circuit works closely with the MIT and bus transmit and receive signals.
The μGENI uses dual port RAM to exchange data. This is done between the 6303-microprocessor and a manager microprocessor - 64180. As the two processors run two separate systems, the dual port RAM ensures they both have equal access. This is controlled by a GAL, delivering memory to either processor on a byte-by-byte basis. The 64180 also has a separate 8Kb of RAM for its exclusive use.
The user should mount the μGENI to the motherboard using spacers. This is done by putting screws, standoffs or plastic PCB supports in the four corner holes of the motherboard. Do not use any adhesive product on the board.It is important that the μGENI board is not mounted in a way that obstructs airflow across the board. Users should take care not to mount it within 1/8 inch of any other board or component on the motherboard.
