>>>>>型號(hào):1756-DHRIO 遠(yuǎn)程 I/O 通信接口模塊 具體取決于電纜長(zhǎng)度
【功能描述】
Allen-Bradley 1756-DHRIO 是一款 ControlLogix Data Highway Plus/遠(yuǎn)程 I/O 通信接口模塊。該模塊有兩 （2） 個(gè)通道，支持每秒 57.6 KB、每秒 115.2 KB 和每秒 230.4 KB 的通信速率，具體取決于電纜長(zhǎng)度。它最多可以通過(guò)三個(gè)機(jī)箱和四個(gè)通信網(wǎng)絡(luò)傳輸消息。通過(guò)該模塊，即使在不同的網(wǎng)絡(luò)上，PLC、SLC 和 ControlLogix 控制器等設(shè)備之間也可以進(jìn)行信息交換。
它支持以下類(lèi)型的通信：設(shè)備之間的遠(yuǎn)程 I/O、控制和信息協(xié)議 （CIP） 消息傳遞以及 Data Highway Plus （DH+） 消息傳遞。它最多可以有 32 個(gè) Logix 連接，遠(yuǎn)程 I/O 鏈路可以連接到遠(yuǎn)程 I/O 設(shè)備以及其他智能設(shè)備。當(dāng)連接到遠(yuǎn)程 I/O 網(wǎng)絡(luò)時(shí)，它可以充當(dāng)適配器或掃描儀，即使在沒(méi)有消息指令的情況下也能傳輸模擬、數(shù)字、塊和特殊數(shù)據(jù)。在安裝 1756-DHRIO 模塊之前，您需要對(duì)每個(gè)通道的網(wǎng)絡(luò)類(lèi)型交換機(jī)進(jìn)行編程，并安裝和連接 ControlLogix 電源和機(jī)箱。您可以在同一機(jī)箱中安裝盡可能多的模塊，但這取決于您的可用電源。請(qǐng)注意，即使在施加機(jī)箱電源時(shí)，也可以安裝或拆卸模塊，但您需要遵守安全預(yù)防措施，特別是該區(qū)域是無(wú)害的，并且電源已斷開(kāi)，以防止電弧可能導(dǎo)致模塊和連接器的觸點(diǎn)過(guò)度磨損。確保釋放電位靜電，因?yàn)槟K對(duì)靜電放電很敏感。

【英文介紹】
The Allen-Bradley 1756-DHRIO is a ControlLogix Data Highway Plus/ Remote I/O communication interface module. The module has two (2) channels and supports communication rates of 57.6 kilobits per second, 115.2 kilobits per second and 230.4 kilobits per second, depending on cable length. It can transmit messages through up to three chassis and four communication networks. With this module, information can be exchanged between devices such as PLCS, SLCS and ControlLogix controllers, even on different networks.
It supports the following types of communication: remote I/O, Control and Information Protocol (CIP) messaging between devices, and Data Highway Plus (DH+) messaging. It can have up to 32 Logix connections, and remote I/O links can connect to remote I/O devices as well as other smart devices. When connected to a remote I/O network, it can act as an adapter or scanner, transmitting analog, digital, block, and special data even in the absence of message instructions. Before installing the 1756-DHRIO module, you will need to program the network type switches for each channel and install and connect the ControlLogix power supply and chassis. You can install as many modules as you want in the same chassis, but it depends on your available power supply. Note that a module can be installed or removed even when a case power supply is applied, but you need to follow safety precautions, especially if the area is harmless and the power supply is disconnected to prevent arcing that may cause excessive wear on the contacts of the module and connector. Make sure to release the potential static electricity, as the module is sensitive to electrostatic discharge.
