SIMATIC NET modules. It is used on the following:
 PROFIBUS modules
 Industrial Ethernet modules
 Modules for Gateways (for example, IE/PB Link)
Installation
The firmware loader is available when you have installed NCM S7 on your PG/PC.
Load Files
The Firmware Loader supports the following file types:
 <file>.FWL
A file form that contains extra information that can be displayed in the dialogs of
