Features
input process data read and output process data write
SDO read and write
EEPROM read and write
FoE read and write

EoE
Beware that real-time applications need some special considerations.
Requirements
Linux
Python 3
GCC (installed on your machine)
Python scripts that use PySOEM must be executed under administrator privileges
Windows
Installation
python -m pip install pysoem
or
pip install pysoem
