Recording data

This function block records the current values of variables when a high –signal at the input "bStore" is present. The values are stored in a file parameterized in a universal binary format.

Does at the same time the input "bReset" a high signal is present,

  • Either completely reset the previous file
  • Or if the filename or path has changed, a new file is created.

At the output of “State", the current state is shown.


Changes the structure of the recording (for example, adding or deleting of variables, etc.) a new filename and/or path must be specified! If this is not done, an existing file is no longer being evaluated!


The parameters are set via the parameter dialog by selecting a name from the list of the recorder. This list is provided in the data point administration (see Tools menu).


Name I/O Type(s) Function
DRCPath I DYNTEXT File path
DRCName I DYNTEXT File name
bStore I BIT Save
bReset I BIT Reset or new
State O UCHAR State


Unused or incorrectly configured recorder blocks are marked when downloading.

Important: Pay attention to block sequence! The block numbers at the inputs "Path" and "State" have to be lower than the block number of the Data Recorder block.

In Linux-based systems, the path (DRCPath) is the extension of a pre-configured path. The configuration is done in the run-time kernel associated configuration file. For example:
