java 使用modbus协议通讯遇到的问题

在项目中使用了modbus通讯相关的jar如下：

modbus4J.jar

RXTXcomm.jar

seroUtils.jar

rxtxParallel.dll

rxtxSerial.dll

 

在使用过程中遇到了几个恶心的坑，主要是RXTXcomm.jar 和 rxtxParallel.dll、rxtxSerial.dll的版本一致性问题

还有modbus4J.jar和seroUtils.jar的版本也必须一致。

 

RXTXcomm.jar 和 rxtxParallel.dll、rxtxSerial.dll的版本不一致：

modbus4J.jar和seroUtils.jar的版本不一致：
modbusFactory.createRtuMaster(serialParameters);会报异常错误，关键是网上总是找不到合适的jar，所以我把整理好的jar包放到了网盘中，需要的可以下载
