Abstract

本申请实施例公开了一种数据采集方法、装置、Modbus系统及存储介质，属于通信技术领域。在本申请实施例中，主机与从机一次交互采集一个或多个分段数据，每个分段数据携带的数据数量最大为256。在Modbus系统中，一个数据最小以一字节表示，则每个分段数据携带的数据可达256字节，如果一次交互采集到多个分段数据，那么能够采集的数据量将远大于协议限制的252字节。也即本方案中一次交互能够采集的数据量更多，在需要采集的数据量一定的情况下，能够减少主机与从机的交互次数，这样总线占用频率降低但占用率提高。且由于从机一次响应的数据量更多，主机不会长时间耗费在一个从机上，因此，Modbus系统的实时性将提高。
