technical data. Ä Chap. 3.3 ‘Technical data’ page 54
The memory is divided into the following parts:
n Working memory for temporary data and parts of the user program.
n Parametrization memory for current firmware and overlay file system with firmware
adjustments, user program and data.
n Non-volatile memory for retentive data.
Ä Chap. 4.5 ‘Memory management’ page 67
