I am trying to understand the firmware of a Grundfos CIM 500 product. The CIM 500 is a control module for grundfos pumps which uses a web interface.
From binwalk I have found that it is running eCos, but I have a very hard to to extract any information, file structure, ram file, disk images or anything of that matter.
I was hoping someone here with more experience with firmware analysis could give some help with what this firmware is, if it is compressed/encrypted, what kind of architecture the module is running, and how i could get more information from it.
I have viewed it in a hex editor and found traces of HTML, but no files or informative file headers.
The firmware is available on the Grundfos software page (https://www.grundfos.com/dk/support/software), or directly here:
