欧姆龙CP系列PLC做MODBUS RTU从站，一招搞定 - 腾讯云
大家好，今天我来给大家介绍一下cp系列plc的串行通讯功能，具体是如何配置为modbus_rtu从站的。 欧姆龙的PLC在国内非标自动化行业中应用相当广泛，且价格相对经济。
Modbus 协议广泛应用于各种工业控制设备中，欧姆龙的变频器3G3MZ、3G3RV、3G3MZ 都支持Modbus－RTU 通信，因此通过CP1H 的串行通信接口，可以简单经济的实现和欧姆
双击左侧工程选项板设置，选项板1选择NX1W-CIF11，通讯模式为Modbus-RTU 主机，波特率设为9600bps，数据位8位，停止位1位，偶校验，然后同步至PLC。 图2-6
Modbus RTU Master - CP2E Function Block - OMRON Industrial Automation
Use the Modbus RTU protocol for communication with inverters when performing velocity control for packing machines where RS -485 serial communication is used to set and monitor inverters directly from the PLC. Execute 5 types of Modbus RTU commands. Select function blocks to suit your application and set parameters. * Scroll left and right to see.
Which OMRON PLCs can perform Modbus Communications
May 19, 2023 · Modbus RTU and Modbus ASCII. Modbus RTU is the most common form of the protocol and is used on any serial communications layer such as RS232, RS485 and RS422. It is a binary protocol. Modbus ASCII is similar to RTU in that it also is used on serial networks, however all values are encoded in ASCII characters.
