应用
OBT(光学总线终端)用于连接PROFIBUS
站没有积分光学接口或PROFIBUS DP
RS485段到光线。然后是现有的DP设备
提供了光学数据传输的优点。
PROFIBUS站连接到RS 485界面
the OBT via a cable terminated at both ends, e.g. connecting
电缆830-1t。该电源使用
两个光学接口。
The following optical transmission media can be connected to
找不到:
•
Plastic fiber-optic cables can be used up to an individual
segment length of 50 m. They can be configured very easily
on site with 2 x 2 Simplex connectors.
•PCF
1)
光纤电缆可用于个体
分段长度高达300米。这些电缆是预测的。
The OBT supports all PROFIBUS data transmission rates up to
12.Mbit/s.

设计
The OBT has a compact plastic housing. It is suitable for
mounting on a DIN rail or for wall mounting with a mounting plate
借助于两个洞钻孔。
The OBT has the following connections:
•
用于连接PROFIBUS DP节点的9引脚子D插座
如编程设备(PG),PC,操作员面板(OP),
S7-300或没有积分光学元件的节点,例如,ET 200s或
PROFIBUS DP components from other suppliers or a
PROFIBUS DP-RS 485段。
•
用于连接塑料和PCF的两个光学接口
fiber-optic cables with Simplex connectors (connection to
CP 342-5 FO, CP 5613 FO, IM 153-2 FO, IM 467 FO or to
ET 200与集成光学)
•
24 V DC进给电源
■
功能
•
通过连接连接与RS 485接口的电台
cable 830-1T or PROFIBUS cable with bus connectors
(在两端终止)或RS 485段
•
在光线上提供电气连接点
(例如,启动和诊断的PG连接)。
•
支持从9.6 kbit / s的所有PROFIBUS数据率
12.Mbit/s including 45.45 kbit/s for PROFIBUS PA
•
Regeneration of the signals in amplitude and time
•
Cascade depth when using user-defined bus parameters up
to 126 stations
•
Galvanic isolation of the station via fiber optic cable
•
通过LED显示器进行简单的诊断,用于操作电压为
以及收到数据CH1,CH2和CH3。
