TRIO塊,如圖79所示,是獨(dú)立的、可配置的I/O塊,用于將現(xiàn)場(chǎng)設(shè)備連接到CI862通信總線。這些塊可以單獨(dú)安裝在機(jī)器上、接線盒中,也可以分組安裝在機(jī)架或面板中。TRIO塊由鑄鋁制成,重量約為1.8千克(4磅)。它的尺寸約為22.5 x 10 x 7.5厘米(9 x 4 x 3英寸)。每個(gè)塊都有自己的通信能力和微處理器,并提供6到32個(gè)電路用于連接輸入和輸出設(shè)備。您可以在總線上以任何組合或順序放置塊。你可以在同一輛公交車上混合使用積木。各種類型的模塊可用功能框圖完整的CI862K01單元由一個(gè)TP862基板、一個(gè)CI862通信接口板及其機(jī)械組成,如圖80所示。所有電子設(shè)備和所有功能都位于板上,該板還包括μGenie從模塊?;搴虲I862通過(guò)一個(gè)80引腳的邊緣連接器連接。與外界的連接是在基板上進(jìn)行的。
TRIO blocks, Figure 79, are self-contained, configurable I/O blocks used to interface field devices to the CI862 communications bus. These blocks can be individually installed on machines, in junction boxes, or grouped in racks or panels. A TRIO block is made of cast aluminum, and weighs approximately 1.8 kgs (4 pounds). It measures approximately 22.5 x 10 x 7.5 cm (9 x 4 x 3 inches). Each block has its own communications capability and microprocessor, and provides from 6 to 32 circuits for connecting input and output devices. You can place blocks on the bus in any combination or sequence. You can use a mix of blocks on the same bus. Various types of blocks are available Functional Block Diagram A complete CI862K01 unit consists of a TP862 baseplate, a CI862 communication interface board, and their mechanics, Figure 80. All electronic devices and all functions are located on the board which also includes the μGenie slave module. The baseplate and CI862 are connected via an 80-pin edge connector. Connections to the outside world are made on the baseplate.
