4.4.2 Generating the system.txt Configuration File
This section describes the procedure for generating a system.txt configuration file and details any operating
system specific differences in behavior among the development packages.
First, the file must contain LOCAL declarations for all modules that are to run on the host computer. At a
minimum, this must include the ssdm module and the timer module. Hence, the following declarations must
exist:
LOCAL 0x20 * ssdm - Board interface task
LOCAL 0x00 * tim_xxx - Timer task
LOCAL declarations are also required for any optional modules running on the host. Typically, this includes
the s7_mgt protocol configuration utility and the user's own application module. It may also include any host-
based protocol modules and the s7_log utility. For example:
LOCAL 0xcf * s7_mgt - Management/config task
LOCAL 0x2d * upe - Example user part task
LOCAL 0x3d * s7_log - Prints messages to screen/file
LOCAL 0x22 * MTP3 module
Once all the LOCAL declarations are in place, REDIRECT commands should be added for all modules that are
logically running on the board so that any messages destined for these modules are transported via the ssdm
module (module_id = 0x20).
The following REDIRECT commands are always required:
REDIRECT 0x71 0x20 * MTP2 module_id
REDIRECT 0x10 0x20 * LIU module
REDIRECT 0x8e 0x20 * onboard management module
If ATM support is required, then the following REDIRECT commands are also required:
REDIRECT 0x31 0x20 * ATM Module
REDIRECT 0x41 0x20 * Q.SAAL Module
Having ensured that all modules running on the board are accessible, it is then necessary to ensure that any
status indications issued from the board successfully arrive at a module running on the host. If this does not
happen, the system quickly runs out of available messages for inter-process communication.
Two module_ids (0xdf and 0xef) require redirection to a suitable process running on the host; initially these
messages should be redirected to the s7_log utility that prints out a line for each message received.
Ultimately, the user's own application should deal with these notifications.
REDIRECT 0xdf 0x3d* LIU/MTP2 status messages -> s7_log
REDIRECT 0xef 0x3d* Other indications -> s7_log
