Question

在Windows10上运行OpenHab2，我无法让OpenHAB2从串行端口请求保留寄存器数据。在该端口上未看到MODBUS请求。我安装了NTP绑定（ntp时间）（可以工作），并尝试了Modbus绑定1.12.0，尽管它仅对OpenHAB1有效。

我的OpenHAB2配置是

.sitemap

    sitemap boiler label="My home" 
    {
        Frame label="Date" 
        {
          Text item=Date
          Text item=holding1501 label="Holding1501 out[%.1f °C]"
          Text item=holding1500 label="Holding1500 out[%.1f °C]"
        }
    }

.items

    DateTime Date  "Date [%1$tA, %1$td.%1$tm.%1$tY %1$tH:%1$tM:%1$tS]"  { channel="ntp:ntp:local:dateTime" }
    Number holding1501 "Holding1501 [%.1f]" <temperature> {channel="modbus:data:localSerial:holding:holding1501:number"}
    Number holding1500 "Holding1500 [%.1f]" <temperature> {channel="modbus:data:localSerial:holding:holding1500:number"}

和.things

    Bridge modbus:serial:localSerial [port="COM6", id=10, baud=19200, stopBits="1", parity="even", dataBits=8, encoding="rtu"]
    {
        Bridge poller holding [ start=1500, length=1, refresh=1000, type="holding" ] 
        {
            Thing data holding1500 [ readStart="1500", readValueType="int16", writeStart="1500", writeValueType="int16", writeType="holding" ]
            Thing data holding15011 [ readStart="1501", readValueType="int16", writeStart="1501", writeValueType="int16", writeType="holding" ] 
        }
        Thing data holding1500 [ readStart="1500", readValueType="int16", writeStart="1500", writeValueType="int16", writeType="holding" ]
        Thing data holding15011 [ readStart="1501", readValueType="int16", writeStart="1501", writeValueType="int16", writeType="holding" ] 
    }

要使MODBUS进入OpenHAB2，我缺少什么。对一些教程或工作示例的引用将不胜感激。

Answer 1

最终找到了解决方案：OpenHAB 2.3.0在MODBUS v2.x上不起作用。使用OpenHAB2 2.4.0（快照）时，MODBUS RTU正常工作（使用com0com将OH2桥接到MOD_RSsim）。未能使MODBUS / TCP正常工作，似乎是IP端口连接问题）

OpenHAB2访问MODBUS RTU从站设备
