GE 8502-BI-DP  总线接口模块

【产品详情】

8502-BI-DP (Bus Interface Module) BIM提供8000系列I/O模块与a之间的通信链路profibus – dp主机。它从模块中高速采集数据而局域网的运行速度高达6mbaud，允许主机对快速响应控制过程中的条件。

BIM收集I/O模块的数据并制作可根据主人的要求提供。它是Profibus主机的一个奴隶。以及循环数据交换，这是读取输入所必需的BIM支持Profibus Extended，支持输出数据的写入诊断状态信息。它还支持许多已经实现的特殊功能，以允许高完整的系统操作和现场维护。

◆连接MTL8000节点到Profibus-DP主机局域网

◆最多支持24个I/O模块 HART过程和状态变量通过Profibus-DP

◆扩展模块和通道状态诊断

◆局域网速度高达6mbaud

◆配置用非易失性存储器

◆软件可通过本地端口或Profibus主机配置 HART®通过通信适配器进行维护

8502支持从Profibus主机进行参数化。这以“每个模块”为基础配置，即所有通道都在一个通道上模块携带相同的配置。配置创建于使用GSD文件中提供的详细信息的Profibus配置器。此方法速度快，并且可以基于此构建配置在表示物理模块的“逻辑”模块上。模块一次添加一个到配置和参数被选择应用于模块的所有通道。

可以选择逻辑模块来提供HART状态和流程变量在Profibus-DP循环输入电报。此外，对于在需要访问许多HART变量的应用程序中可以使用HART“邮箱”。该技术收集HART变量按要求的;在电报中节省空间，有时过度处理数据。此方法仅在使用时可用参数化。

配置由Profibus主站向下传递给BIM在会议开始时。如果系统停止并重新启动，则配置文件重新传输到BIM。

【英文介绍】

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.
