2.5 FB200 "Safety"

Figure 2-8: Writing parameters – response data record (response DB)

If the parameters are changed incorrectly, an error data record is output for each

incorrect parameter. Its structure and the error codes can be found in the

SINAMICS S120 function manual

FB200 "Safety"

The F functionality of the example is confined to using the respective signals of the

F input module for controlling/disabling the individual safety functions in the

SINAMICS S120 drives.

Furthermore, the passivation bit of the F input module and the SINAMICS S120

drives are read, and the acknowledge signal for reintegrating both 'modules' is

used.

The safety bits of the SINAMICS S120 can be accessed just as the bits of

F-DI/DOs in the safety program:

In the example, the input bytes 0 and 1 contain the safety status word 1 of

drive 1 and the input bytes 6 and 7 the safety status word 1 of drive 2.

In the example, the safety control word 1 of drive 1 is sent via the output bytes

0 and 1 and safety control word 1 of drive 2 is sent via the output bytes 6

and 7.

FB200, FC201 and FC202 are blocks that can be edited by the user. FB200 calls

the save functions FC201 and FC202. They control the safety functions of the

drives via PROFIsafe. In the example, they read the safe inputs of the F input

module and write the respective functions of the PROFIsafe frames of drive 1

and 2.
