2.产 品 详 情 资 料：
ABB SPNIS21您可能有硬件问题。检查多点电缆；它可能接线错误、损坏或断开。其中一个接头上的导线可能松动。还要检查您尝试连接的PLC的状态。它可能没有通电；它可以被停止；或者它可能有其他问题。通过将编程器直接连接到PLC的编程器端口，消除PLC本身可能存在的问题。即使编程软件配置为Multidrop，只要SNP ID匹配。收发器主体上的连接器为标准RJ-45型，ABB SPNIS21用于连接到非屏蔽双绞线（UTP）以太网电缆。该单元有一个附带的40“（1米）电缆，带有标准14针AAUI连接器，用于连接至具有以太网接口电源和链路完整性LED指示灯的90-30系列以太网模块ABB SPNIS21或CPU。
You may have a hardware problem. Inspect the multidrop cable; it may be wired incorrectly, damaged, or disconnected. A wire may be loose on one of the connectors. Also check the status of the PLC you are trying to connect to. It may not be powered up; it may be stopped; ABB SPNIS21or it may have some other problem. Eliminate the PLC itself as a possible problem by connecting your programmer directly to the PLC’s programmer port. You should be able to communicate with a PLC using this direct connection even if the programming software is configured for Multidrop, as long as the SNP IDs match.Connector on transceiver body is standard RJ-45 type for connection to unshielded twisted pair (UTP) Ethernet cable This unit has an attached 40" (1 meter) cable with standard 14-pin AAUI connector for connecting to a Series 90-30 Ethernet moduleABB SPNIS21 or CPU with Ethernet interface Power and Link Integrity LED indicator lights.
