西门子ET200SP总线适配器

BusAdapter BA 2xRJ45

BusAdapter BA 2xFC

SIMATIC ET 200SP 的接口模块具有一个用于总线适配器的通用 PROFINET 接口。 使用适宜的总线适配器，可根据特定应用的要求来调整连接类型：

• 对于具有中等机械负荷和 EMC 负荷的标准应用，可使用 BA 2xRJ45 总线适配器。该适配器具有用于标准 RJ45 插头的两个插座。
• 对于各个部件要承受较高机械和/或 EMC 负荷的机器与系统，建议使用 BA 2xFC 总线适配器。 在此情况下，将通过 FastConnect 端子来直接连接总线电缆（与 PROFIBUS 连接器类似），这已在无数应用中得到证明。采用这种技术时，组装极为迅速，与 RJ45 插入式连接器相比，抗振性和抗电磁干扰性均提高 4 倍。
• 带有光纤电缆连接用总线适配器可用于覆盖两个站和/或较高 EMC 负载之间的较高电位差。

该总线适配器的另一个优点是： 其目的是：修理出现问题的 RJ45 插座、后期转用可靠的 FastConnect 技术或者光纤连接技术时，仅仅只需更换该适配器。

以下接口模块通过总线适配器来提供 PROFINET 连接：

• IM 155-6PN 标准型
• IM 155-6PN 高性能型

ET 200SP BusAdapter “BA-Send"

BA-Send BusAdapters are used whenever an existing ET 200SP station is to be expanded with IP67 modules of the SIMATIC ET 200AL.

The SIMATIC ET 200AL is a distributed I/O device with degree of protection IP65/67 that is easy to operate and install. Due to its high degree of protection and ruggedness as well as its ***all dimensi*** and low weight, the ET 200AL is especially suitable for use at the machine and on moving plant secti***. SIMATIC ET 200AL enables the user to access digital and analog signals and IO-Link data at low cost.

SIMATIC BusAdapters

In standard applicati*** with moderate mechanical and EMC loads, SIMATIC BusAdapters with an RJ45 interface can be used, e.g. the BusAdapter BA 2xRJ45.

For machines and systems in which higher mechanical and/or EMC loads act on the devices, a SIMATIC BusAdapter with connection via FastConnect (FC) or fiber-optic cable (SCRJ or LC) is recommended. Likewise, all SIMATIC BusAdapters with a fiber-optic cable connection (SCRJ, LC) can be used with the increased loads.

BusAdapters with connecti*** for fiber-optic cables can be used to cover high potential differences between two stati*** and/or high EMC loads.

An overview of the essential properties of the PN interfaces is shown in the table below

可方便地将此总线适配器插到接口模块中，然后用螺丝进行固定。

该总线适配器可配有参考标识牌。
