Documenting a Safety Matrix
A Safety Matrix is documented via menu item "Options > Reports > Configuration Report".
This displays all of the configurations in the matrix in a text file; they can then be printed or
saved in this format. The same matrix can be reconfigured on the basis of this text file,
or a hard copy of it can be printed out via the menu item "File > Print...". In order to ensure
that as much information as possible is retained in this printout, activate all options on the
"General" tab prior to printing (accessible via "View > Adapt > Layout"); otherwise, fields that
are not visible will not be printed. Please note that this type of printout does not meet the
criteria of an acceptance document, as it lacks key information such as a signature and
cyclic interrupt OB.

Organizing matrices into different shutdown groups

The information below is intended to demonstrate how two matrices located in different
shutdown groups but the same OB are installed. This is carried out using S7 F-
Systems Lib V1_3.
Creating shutdown groups
The F-module driver of an F-signal module may only be assigned to one shutdown group.
Therefore, when creating shutdown groups you must make sure that all signals in an F-
signal module are used in the same shutdown group. The use of signals in an F-signal
module in different shutdown groups results in errors during compiling due to invalid
interconnections.
In the example below, the intention is to have two matrices be executed with a matrix cycle
time of 300 ms, but in separate shutdown groups.
