Elfin EW11 TCP 客户端不发送数据

Question

我想使用 Elfin EW11 设备作为 Modbus TCP 客户端/主站向 Modbus TCP 服务器/从站（另一个 Elfin EW11）发送请求。它通过 RS485 连接到我的测试计算机/PC。

PC ---RS485--> Elfin EW11 TCP 客户端 ---WLAN---> Elfin EW11 TCP 服务器---RS485--->IOT 设备

Elfin EW11 Modbus TCP 客户端应接收来自 RS485 接口的请求，并通过 WLAN 将其发送到 Modbus TCP 服务器。

它出现在其状态页面中，

1. 已连接到服务器 2、收到RS485的请求，但是
2. 不向服务器发送任何内容

参见 Modbus TCP 客户端状态页面的屏幕截图

我已经尝试过了 A。 Modbus TCP 服务器。当通过 WLAN 直接从我的 PC 查询时，它响应良好 b. TCP 客户端配置中的几个选项、超时等。没有成功。 没有数据从 TCP 客户端传输到 TCP 服务器

我预计至少会传输一些字节，即使 Modbus 请求是错误的。

插入：我非常确定从我的 PC 发送的帧/modbus 请求的格式正确（请参阅下面的评论）

有人有 Elfin EW11 作为 Modbus TCP 客户端吗？
