2.5 Software loading

The program memory on the CPU board is loaded with monitor software and selected
language files at the factory. The software is used for running all the functions that are
integrated into the PC board. For service upgrade main software and language files, please

The detailed structure of a parameter module depends on the specific needs for each
individual parameter. However, some common parts are used in the parameter modules. The
electronics inside the module is usually divided into isolated (floating) and non-isolated
sections. Typically, the non-isolated section consists of buffers to interface the parameter
module to the module bus while the rest of the electronics is located in the isolated section. The
isolated section includes the microcontroller together with memory components, the front-end
analog electronics (amplifiers, etc.) and sensor drivers.
