IS215UCVEM08B控制模块现货

产品详细资料
RS485/RS422通信745为用户提供了两个可以同时使用的后部通信端口。两者都实现了《GEK-106636A:745通信指南》中概述的AEG Modicon Modbus协议的子集。COM1端口可用于二线制RS485模式或四线制RS422模式，但不会同时在两种模式下工作。在RS485模式下，数据传输和接收通过一对双绞线完成，传输和接收数据在相同的两根导线上交替。这些电线应连接到标有RS485的端子上。RS422模式使用指定为RS485的COM1端子用于接收线路，使用指定为RS422的COM1终端用于发送线路。COM2端口仅用于双线RS485模式。通过使用这些端口，可以从远程计算机、SCADA系统或PLC进行连续监测和控制。为了大限度地减少噪声带来的误差，建议使用屏蔽双绞线。还应遵守正确的极性。例如，继电器必须与所有B1端子（标记为COM1 RS485+）连接在一起，所有B2端子（标记COM1 RS485–）连接在一同。端子B3（标记为COM1 RS485 COM）应连接到屏蔽内部的公共电线。为了避免回路电流，屏蔽应仅在一点接地。
RS485/RS422 Communications The 745 provides the user with two rear communication ports which may be used simultaneously. Both implement a subset of the AEG Modicon Modbus protocol as outlined in publication GEK-106636A: 745 Communications Guide. The COM1 port can be used in the two-wire RS485 mode or the four-wire RS422 mode, but will not operate in both modes at the same time. In RS485 mode, data transmission and reception are accomplished over a single twisted pair with transmit and receive data alternating over the same two wires. These wires should be connected to the terminals marked RS485. The RS422 mode uses the COM1 terminals designated as RS485 for receive lines, and the COM1 terminals designated as RS422 for transmit lines. The COM2 port is intended for the two wire RS485 mode only. Through the use of these ports, continuous monitoring and control from a remote computer, SCADA system or PLC is possible. To minimize errors from noise, the use of shielded twisted-pair wire is recommended. Correct polarity should also be observed. For instance, the relays must be connected with all B1 terminals (labeled COM1 RS485+) connected together, and all B2 terminals (labeled COM1 RS485–) connected together. Terminal B3 (labeled COM1 RS485 COM) should be connected to the common wire inside the shield. To avoid loop currents, the shield should be grounded at one point only.
