【功能描述】
8502-BI-DP (Bus Interface Module) BIM提供8000系列I/O模塊與a之間的通信鏈路profibus – dp主機(jī)。它從模塊中高速采集數(shù)據(jù)而局域網(wǎng)的運(yùn)行速度高達(dá)6mbaud，允許主機(jī)對(duì)快速響應(yīng)控制過(guò)程中的條件。
BIM收集I/O模塊的數(shù)據(jù)并制作可根據(jù)主人的要求提供。它是Profibus主機(jī)的一個(gè)奴隸。以及循環(huán)數(shù)據(jù)交換，這是讀取輸入所必需的BIM支持Profibus Extended，支持輸出數(shù)據(jù)的寫入診斷狀態(tài)信息。它還支持許多已經(jīng)實(shí)現(xiàn)的特殊功能，以允許高完整的系統(tǒng)操作和現(xiàn)場(chǎng)維護(hù)。
◆連接MTL8000節(jié)點(diǎn)到Profibus-DP主機(jī)局域網(wǎng)
◆最多支持24個(gè)I/O模塊 HART過(guò)程和狀態(tài)變量通過(guò)Profibus-DP
◆擴(kuò)展模塊和通道狀態(tài)診斷
◆局域網(wǎng)速度高達(dá)6mbaud
◆配置用非易失性存儲(chǔ)器
◆軟件可通過(guò)本地端口或Profibus主機(jī)配置 HART?通過(guò)通信適配器進(jìn)行維護(hù)
8502支持從Profibus主機(jī)進(jìn)行參數(shù)化。這以“每個(gè)模塊”為基礎(chǔ)配置，即所有通道都在一個(gè)通道上模塊攜帶相同的配置。配置創(chuàng)建于使用GSD文件中提供的詳細(xì)信息的Profibus配置器。此方法速度快，并且可以基于此構(gòu)建配置在表示物理模塊的“邏輯”模塊上。模塊一次添加一個(gè)到配置和參數(shù)被選擇應(yīng)用于模塊的所有通道。
可以選擇邏輯模塊來(lái)提供HART狀態(tài)和流程變量在Profibus-DP循環(huán)輸入電報(bào)。此外，對(duì)于在需要訪問(wèn)許多HART變量的應(yīng)用程序中可以使用HART“郵箱”。該技術(shù)收集HART變量按要求的;在電報(bào)中節(jié)省空間，有時(shí)過(guò)度處理數(shù)據(jù)。此方法僅在使用時(shí)可用參數(shù)化。
配置由Profibus主站向下傳遞給BIM在會(huì)議開(kāi)始時(shí)。如果系統(tǒng)停止并重新啟動(dòng)，則配置文件重新傳輸?shù)紹IM。

【英文介紹】
8502-BI- Bus Interface Module (DP) The BIM provides a communication link between the 8000 series I/O modules and the A profibus -DP host. It collects data from modules at high speeds while the LAN operates at speeds up to 6mbaud, allowing the host to respond quickly to conditions during control.
BIM collects data from I/O modules and makes them available at the owner's request. It's a slave to the Profibus mainframe. As well as cyclic data exchange, which is necessary to read the input BIM supports Profibus Extended, which supports writing diagnostic status information to the output data. It also supports a number of special features that have been implemented to allow for high integrity system operation and field maintenance.
◆ Connect the MTL8000 node to the Profibus-DP host LAN
◆ Supports up to 24 I/O module HART processes and state variables via Profibus-DP
◆ Expansion module and channel status diagnosis
◆ LAN speed up to 6mbaud
◆ Configure with non-volatile memory
The software can be maintained via a local port or Profibus host configured with HART? via a communication adapter
The 8502 supports parameterization from the Profibus host. This is configured on a "per module" basis, that is, all channels on one channel module carry the same configuration. The configuration is created by the Profibus configurator using the details provided in the GSD file. This method is fast and builds can be configured based on it on "logical" modules that represent physical modules. Modules are added one at a time to the configuration and parameters are selected to apply to all channels of the module.
Logic modules can be selected to provide HART state and process variables in the Profibus-DP loop input telegrams. In addition, HART "mailboxes" can be used for applications that require access to many HART variables. The technique collects HART variables as required; Saving space in telegrams and sometimes over-processing data. This method can be parameterized only when used.
The configuration is passed down from the Profibus master to the BIM at the beginning of the meeting. If the system stops and restarts, the configuration file is transferred back to the BIM.
