BES212N Bachmann 使用总线扩展模块 对分布式I/O单元的访问时间不到1.5秒

使用总线扩展模块BES212和BES212/N对分布式I/O单元的访问时间不到1.5秒，最远可达3米的高速连接成为可能。多达六个分布式变电站可以在菊花链拓扑中直接互连。每个变电站又可以处理多达15个M1标准模块。

使用RJ45连接器的接线是这项新技术的一个优点。因此布线非常方便。使用带有总线扩展的I/o不需要特殊的协议。用户可以直接访问这些模块:就像它们是本地的一样。集成24 V电源的总线扩展模块BES212/N为变电站供电。

• 带2个接口的总线扩展从模块
• 总线扩展从属模块，可选集成电源
• 多达6个本地变电站
• 最小信号延迟
• 两个站之间的距离最大为3米
• 从属模块上的集成看门狗

With the bus expansion module BES212 and BES212/N a »high speed« connection up to 3 m away is possible with less than 1.5 µs access time to distributed I/O units. Up to six distributed substations can be directly interconnected in a daisy chain topology. Each substation can in turn handle up to 15 M1 standard modules.

The wiring using RJ45 connectors is one advantage of this new technology. Thus wiring is significantly facilitated. A special protocol is not required to use the I/Os with the bus expansion. The user can access these modules directly: As if they were local. The bus expansion module BES212/N with integrated 24 V power supply provides power for the substation.

• Bus expansion slave module with 2 interfaces
• Bus expansion slave module optionally with integrated power supply
• Up to 6 local substations
• Minimal signal delay
• Distances of up to 3 m between 2 stations
• Integrated watchdog on slave modules
