Data transmitting and receiving system

摘要

A data transmitting and receiving system that can be easily built even in an environment where different models coexist, wherein the data transmitting module checks whether or not the OK file exists in the working area (S2), if the OK file exists (YES at S2), deletes the OK file (S4), and prevents data transmitting modules of other data transmitting apparatuses from accessing to the working area. The data transmitting module writes the FTP file in the working area (S6). After writing the FTP file, the data transmitting module creates an END file in the working area (S8) and declares that the data transmitting module completed writing the FTP file.
