As from the STEP 7 V15 it is possible to use the FileReadC/FileWriteC instructions to read/write ASCII Files from/to SIMATIC memory card. The user could be use it to make possible to input / output data from / to the PLC like recipes, logs, reports, etc. The attached project shows a simple example of usage. The blocks are commanded by the Watch table. TIPs: The file name should contain the path and the extension (like, for example ‘UserFiles\myFile.txt’). The SIMATIC memory card has a big, but limited, number of write cycles, so avoid to write data in short time intervals . Better to trigger the write task just when really necessary.
