2.产 品 详 情 资 料：
ABB G2010 A 10.4ST GENERA物理上，一个典型的SNP多点系统由一个编程器和两个或多个PLC组成，通过“菊花链”型布线布置相互连接，如下图所示。有必要为每个从设备（PLC或选件模块）分配一个唯一的SNP（90系列协议）地址，使用编程软件，如Logicmaster、VersaPro或Logic Developer PLC。编程器使用SNP地址指定将与哪个PLC通信。SNP协议使用RS-422通信标准。ABB G2010 A 10.4ST GENERA注意，PLC或选件模块不通过多点系统相互通信。他们只与程序员通信。一次只能有一个由编程器指定的设备与编程器通信。多点电缆有两种多点电缆来源：GE Fanuc电缆，目录号ABB G2010 A 10.4ST GENERA这种预制电缆可用于PLC安装在同一机柜中的应用，例如冗余系统。这条电缆的长度是40英寸（米）。
hysically, a typical SNP multidrop system consists of a programmer and two or more PLCs interconnected by a “daisy-chain“ type cabling arrangement, as shown in the figure below. It is necessary to assign each slave device (PLC or Option module) a unique SNP (Series Ninety Protocol) address, using programming software such as Logicmaster, VersaPro,ABB G2010 A 10.4ST GENERA or Logic Developer-PLC. The SNP address is used by the programmer to designate which PLC it will communicate with. The SNP protocol uses the RS-422 communications standard. Note that the PLCs or Option modules do not communicate with each other over the multidrop system. They only communicate with the programmer. And only one device, the one designated by the programmer, can communicate with the programmer at a time.Multidrop Cables There are two sources of multidrop cables:GE Fanuc cable, catalog number ABB G2010 A 10.4ST GENERAThis pre-made cable can be purchased for applications where the PLCs are mounted in the same cabinet, such as in the case of redundant systems. The length of this cable is 40 inches ( meter).ABB G2010 A 10.4ST GENERA
