描述
SPS5710-2-LF 內(nèi)部有處理器,內(nèi)存,內(nèi)部檢測等電路
SPS5710-2-LF控制器的底板。(C系列硬件都是由底板和模件兩部分組成,模件是插在底板上,用螺栓固定)
底板上會有好多接口用于SPS5710-2-LF控制器與其它部分的連接。
模件
模件是控制部分的主體,內(nèi)部有處理器,內(nèi)存,內(nèi)部檢測等電路,控制部分的主要工作將在這里完成;模件上有LED燈和顯示屏,在這里能獲取到很多C300工作過程或故障中的各種信息
FTE網(wǎng)設(shè)備索引號
網(wǎng)絡(luò)中C300區(qū)別于其它節(jié)點(服務(wù)器、操作站、其它C300)的標識,可以理解為C300的IP地址(C300和服務(wù)器、操作站等都在同一個FTE網(wǎng)絡(luò)中,網(wǎng)絡(luò)中各個節(jié)點之間靠IP來區(qū)分)
備用電池接口
用專用電纜連接備用電池,目的是當C300沒電的時候保持C300內(nèi)存RAM里的最新組態(tài)策略不丟失。
GPS時鐘源網(wǎng)絡(luò)接口
在自控系統(tǒng)中時鐘同步非常重要,也就是系統(tǒng)中的每個節(jié)點的時間最好一致。如果網(wǎng)絡(luò)中的每個節(jié)點的時間都取得GPS時鐘源設(shè)備,時鐘很容易保持一致。C300控制器可利用這個網(wǎng)口連接外部時鐘源,從時鐘源獲取時間。如這個網(wǎng)口未插網(wǎng)線去連接時鐘源,那么C300時間可通過軟件設(shè)定來源于服務(wù)器。
冗余網(wǎng)口
一對冗余的C300控制器這個網(wǎng)口用網(wǎng)線連接完成主備控制器之間數(shù)據(jù)同步。
連接FTE網(wǎng)的兩個網(wǎng)口
FTE網(wǎng)中任何一個節(jié)點都有兩個網(wǎng)口,用兩個不同顏色的網(wǎng)線連接兩臺不同的交換機(詳情可參閱FTE網(wǎng)),這就是那兩個網(wǎng)口,底板上有標明A和B.
IOLINK接口
C300作為控制部分的核心需要IO卡件的配合,C300的IO卡件就靠這兩對接口去連接IO.C300連接IO能力是有限的,每對接口最多能并聯(lián)40個IO,并且兩對接口連接IO的總數(shù)不能超過64個,而不是80個。(如上面接口并聯(lián)40個,那么下面接口只能接24個了)。接口成對出現(xiàn)也是冗余的概念,也就是每個IO卡件都有倆根IOLINK電纜與C300連接,斷一條不影響運營。
SPS5710-2-LF 內(nèi)部有處理器,內(nèi)存,內(nèi)部檢測等電路
Mainboard of the SPS5710-2-LF controller. (The C series hardware is composed of two parts: the base plate and the module. The module is inserted into the base plate and fixed with bolts.)
There are many ports on the baseboard for connecting the SPS5710-2-LF controller to other parts.
module
Module is the main body of the control part, there are processors, memory, internal detection and other circuits, the main work of the control part will be completed here; There are LED lights and displays on the module, where you can get a lot of information about the working process or fault of the C300
FTE network device index number
The identification of C300 from other nodes (servers, operating stations, and other C300) in the network can be understood as the IP address of C300 (C300, server, operating station, etc., are in the same FTE network, and each node in the network is distinguished by IP).
Standby battery interface
The backup battery is connected with a dedicated cable to keep the latest configuration policies in the C300 RAM intact when the C300 is out of power.
GPS clock source network interface
Clock synchronization is very important in automatic control systems, that is, the time of each node in the system is best consistent. If the time of every node in the network is obtained from the GPS clock source device, the clock is easily consistent. The C300 controller can use this network port to connect to an external clock source and obtain time from the clock source. If this network port is not connected to the clock source, the C300 time can be set by software from the server.
Redundant network port
A pair of redundant C300 controllers This network port is connected by a network cable to synchronize data between the active and standby controllers.
Connect the two network ports of the FTE network
Any node in the FTE network has two network ports, with two different colors of network cables connected to two different switches (see FTE network for details), this is the two network ports, the bottom plate is marked with A and B.
IOLINK interface
As the core of the control part, the C300 needs the coordination of IO cards, and the C300 IO cards rely on these two pairs of interfaces to connect IO. The C300 IO connection capability is limited, each pair of interfaces can be connected to a maximum of 40 IO, and the total number of IO connected by two pairs of interfaces cannot exceed 64, rather than 80. (If the upper interface is connected to 40 in parallel, then the lower interface can only connect to 24). The interface pairs are also redundant concepts, that is, each IO card has two IOLINK cables connected to the C300, and breaking one does not affect operation.
