“Modbus-Response”用于输出前端Modbus节点的返回数据在Node-RED控制台显示的节点，一般不使用。“Modbus-Flex-Connector”用于与Modbus设备动态建立连接的节点，使用该节点需要传入连接所需的参数，以及配置存储连接信息的空间（配置一个新的服务器节点，IP和端口可以任意配置，其余参数根据实际需求调整，这里采用TCP连接并...
With the Modbus TCP Connector data can be accessed via the Modbus TCP protocol. This connector is developed as Connectivity Suite Connector and therefor supports standardized configuration as well as data transfer. The Configuration of the Connector is done with the Common Configurator, which is ...

“Modbus-Flex-Connector”用于与Modbus设备动态建立连接的节点,使用该节点需要传入连接所需的参数,以及配置存储连接信息的空间(配置一个新的服务器节点,IP和端口可以任意配置,其余参数根据实际需求调整,这里采用TCP连接并通过Modbus TCP协议通信,超时时间为1000),其余参数可通过前端节点传入。
根据提供的信息,似乎您在询问西门子的S7-1500 PLC的Modbus TCP通信建立后如何使用“Connected”变量进行判断。首先,“MB_CLIENT”背景数据块中的静态变量"Connected"用于判断连接是否已经建立。当连接成功建立时,这个变量可能会被复位或设置为某个特定的值。这是通过对比第6步中提到的DB2数据块的Connector变量的设置来实...
