SIMATIC Memory Card

Transfer of data
A SIMATIC Memory Card is used to load the neural network and the application into the
TM NPU and to receive data from the TM NPU for further processing.
Before a trained neural network can be used with the TM NPU, this network must be
converted for processing by the AI accelerator, e.g. with Intel® Distribution of OpenVINO™ or
the SIMATIC AI Model Deployer.
The SIMATIC AI Model Deployer converts the neural network and creates an image of the
SIMATIC Memory Card with all required (configuration) files.
The following data structure is copied to the SIMATIC Memory Card:
• "config" folder
– "network.conf": Configuration of the network interface
– "ftpclient.conf": Configuration of the FTP client
– "debug.conf": Enabling of debug mode
• "res" folder
– "npu_app.conf": Each folder with neural network models
• "scripts" folder
– "main.py": Application script
NOTE
Useful information about the configuration files: "network.conf" / "ftpclient.conf" /
"debug.conf" / "npu_app.conf"
• The configuration file "network.conf" is mandatory and must always be provided.
Otherwise, the module does not start.
• The configuration files "ftpclient.conf" and "debug.conf" only have to be provided on the
SIMATIC Memory Card if these functionalities are being used.
• The configuration file "npu_app.conf" can be used for editing parameters relating to the
neural network and the camera. However, the file is not mandatory since the data could
also be entered directly in the MicroPython script (main.py).
