摘要： PROBLEM TO BE SOLVED: To provide a LAN repeater capable of avoiding operational abnormality caused by version mismatching between data loaded to equipment on one LAN side and the data loaded to equipment on the other LAN side.
SOLUTION: A first reception means 11 of a LAN repeater 10 receives version information of data loaded to equipment from the equipment on the side of a trunk LAN 20 and a second reception means 13 receives version information of data from equipment on the side of a base LAN 30. A control means 15 compares the received version information to each other and controls the continuation and stop of relay processing in accordance with a result of the comparison. For example, if the version information agrees completely, the data are relayed; and when there is mismatching, relay processing is stopped. Alternatively, if high-order digits are agree, regardless of whether low-order digits of the version information agree, the data are relayed; and if high-order digits do not agree, relay processing is stopped.

摘要： PROBLEM TO BE SOLVED: To provide a data processing system in which the function of a processing part is not restricted more than required by data replaced with a safe value, etc. resulting from an abnormality. SOLUTION: An information source 11 transmits unit data 40 in which a valid flag 42 is set to "1", a monitoring part 14 monitors the input state of the unit data 40 and when there is the abnormality, outputs prescribed unit data in which the data are at safe values and the valid flag 42 is set to "0" instead of the unit data. Only specified unit data among pieces of unit data outputted by the monitoring part 14 is inputted in a replacement part 16 and when the valid flag of the unit data is "0", alternate data are outputted to a processing part 15. The alternate data are those which do not restrict the function of the processing part 15 differently from the safe value. COPYRIGHT: (C)2007,JPO&INPIT
摘要翻译：要解决的问题：提供一种数据处理系统，其中处理部分的功能不受限于由异常导致的安全值等替换的数据所要求的更多。解决方案：信息源11将有效标志42设定为“1”的单位数据40，监视部14监视单位数据40的输入状态，当发生异常时，输出规定的单位数据其中数据处于安全值，并且有效标志42被设置为“0”而不是单位数据。监视部14输出的各单位数据之间的指定单位数据仅被输入到替换部16，当单位数据的有效标志为“0”时，向处理部15输出交替数据。那些不限制处理部分15的功能与安全值不同的那些。版权所有（C）2007，JPO＆INPIT
