解释"illegal_data_address: exception code = 2"错误的含义 "illegal_data_address: exception code = 2" 这类错误通常出现在涉及内存访问的编程环境中,特别是在使用C、C++这类低级语言时。这个错误代码指示程序试图访问一个非法的数据地址,具体来说,它试图执行一个非法操作码(opcode)或者访问了内存中的一个不允...
非法数据地址(Illegal Data Address): 解释:非法数据地址表示Modbus Poll尝试读取或写入从设备中不存在的数据地址。这可能是由于数据地址设置不正确或数据地址在从设备中不存在引起的。 说明:用户应确认所选的数据地址在从设备中存在,并且地址设置正确。比较Modbus Poll的请求设置与从设备的规格说明,确保数据地址匹配。

Hello all; Here's my scenario. I have a serial Modbus slave (a Woodward EGCP2 controller), from which I'm reading data. Everything was working fine...
I can only see that the Illegal data address error code is generated because of a buffer overrun and/or garbled data in the frame buffer array. As mentioned the starting address has to be equal or larger for the error code 2 to be set. This means the third and/or fourth byte of the...
