ABB NBIO-31 3BSE011337R1 I/O模块在使用远程底板的系统中，连接所有底板的电缆长度不得超过700英尺。Ŷ远程底板不能单独使用。它必须连接到具有CPU的系统。CPU可以位于PLC或配备有个人计算机接口卡的个人计算机中（参见第11章）。Ŷ远程基板内置隔离远程基板中的I/O模块使用的+5伏逻辑电源与与I/O总线扩展接口相关的接口电路电源之间的隔离有助于实现远程功能。隔离有助于防止与不平衡地面条件相关的问题。Ŷ每个系统允许的远程底板的最大数量取决于所使用的CPU类型。对于CPU 331、340和341，最大值为4。对于编号为350或更高的CPU，最大值为7。Ŷ每个远程基板的右端都安装有一个25针的D型母扩展连接器，用于连接其他基板。Ŷ远程底板有两种尺寸；5插槽（IC693CHS398）和10插槽（IC691CHS392）Ŷ远程背板不支持以下智能选件模块：PCM、ADC、BEM330和CMM。ABB NBIO-31 3BSE011337R1 I/O模块这些模块必须安装在CPU基板上。所有其他I/O和选件模块都可以安装在任何类型的基板上。Ŷ远程底板的物理尺寸相同，使用相同类型的电源，并支持与扩展底板相同的I/O和选件模块。Ŷ每个远程基板都有一个机架编号选择DIP开关ABB NBIO-31 3BSE011337R1 I/O模块
英文资料
There can be no more than 700 feet of cable connecting all baseplates in a system that uses Remote baseplates. Ŷ A Remote baseplate cannot stand alone. It must be connected to a system that has a CPU. The CPU can be in a PLC or in a Personal Computer that is equipped with a Personal Computer Interface Card (see Chapter 11). Ŷ Remote capability is facilitated by the Remote baseplate’s built-in isolation between the +5 volt logic supply used by the I/O modules residing in the Remote baseplate and the supply for the interface circuit associated with the I/O Bus Expansion Interface. Isolation helps prevent problems associated with unbalanced ground conditions. Ŷ Maximum number of Remote baseplates allowed per system depends on the type of CPU they are used with. For CPUs 331, 340, and 341, the maximum is 4. For CPUs numbered 350 and higher, the maximum is 7. Ŷ Each remote baseplate has a 25-pin female D-type Expansion connector mounted at its right end for connection to other baseplates. Ŷ Remote baseplates are available in two sizes; 5-slot (IC693CHS398) and 10-slot (IC693CHS392) Ŷ A Remote backplane does not support the following intelligent option modules: PCM, ADC, BEM330, and CMM. These modules must be mounted in a CPU baseplate. All other I/O and option modules can be mounted in any type of baseplate. Ŷ Remote baseplates are the same physical size, use the same type power supplies, and support the same I/O and option modules as the Expansion baseplates. Ŷ Each Remote baseplate has a Rack Number Selection DIP switchABB NBIO-31 3BSE011337R1 I/O模块
