Use the buildin Datalog function. Regards, Marcjan

From manual The S7-200 Explorer is the application used to read a data log from the memory cartridge, and then store the data log in a Comma separated Values (CSV) file. Each time a data log is read, a new file is created. This file is saved in the Data Log directory. The file name is formatted as follows: PLC Address, data log name, date, and time. Regards, Marcjan
