Standard and safety program
The example code supplied is fully functional for the described
application. The individual functions of the example code are
explained in the following Chapters so that you are in a position
to implement your own projects.
Note
In this example code, passwords are used for the safety
functions. These are as follows:
S7 safety program and HW Config: siemens
STARTER Safety Screens: 12345
Settings in the hardware configuration
Properties of the CPU
Before the safety functions of the CPU can be used, they must
be released. The properties window of the CPU is opened by
double clicking on the CPU317F-2.
Under the Protection tab, the safety functions of the CPU are
enabled by selecting the following functions:
■ Level of protection; 1: Access protect for F CPU,
■ Activate Removable with password,
■ Enter a password (in this example code, siemens),
■ Activate CPU contains safety program.
Properties of the F-DI module
The signal sources for the safety functions (pushbuttons to
acknowledge STO, SS1, SLS and Emergency Stop) are read-in
using the fail-safe module DI24xDC24V (6ES7326-1BK01-
0AB0). The Properties dialog box opens after double clicking
on the module. The properties of the module can be parameterized
by selecting the Parameters tab.
