4.2.2 Generating a System Configuration File
This section describes the procedure for generating a system configuration
file (system.txt) and details any operating system specific differences in
behaviour of the development packages.
First, the file must contain LOCAL declarations for all modules that run on the
host computer. As a minimum this must include the SSDS module and the
timer module. Hence the following declarations must exist:
LOCAL 0x20 * ssd / ssds - Board interface task
LOCAL 0x00 * tim_xxx - Timer task
LOCAL declarations are required for any optional modules that run on the
host. Typically, this includes s7_mgt and the user's own application module.
It may also include host-based protocol modules and the s7_log utility. For
example:
