S_SetMode input

Edge-triggered input for confirming or enabling the operating mode set at S_Mode0 to S_Mode7.

Data type: SAFEBOOL
Initial value: SAFEFALSE

Manual confirmation (positive edge at the S_SetMode input) is required if AutoSetMode is set to FALSE.

Hinweis
If AutoSetMode = TRUE, the set operating mode is automatically accepted.
This depends on:
  • The function block being activated (Activate = TRUE)
  • and no error being present (Error = FALSE)
  • and mode selector switching not being locked (S_Unlock = SAFEFALSE).

Connection: Connect this input to a button (e.g., key switch) connected to the Sicherheitssteuerung, either directly or via other safety-related functions/function blocks. Constant SAFETRUE or SAFEFALSE values are not permitted.

The function block performs internal edge monitoring for the S_SetMode input. The function described is only executed on a positive signal edge. An additional static SAFETRUE signal after a positive signal edge has no effect.

In those states where a positive edge is required at S_SetMode, the function block regards a static SAFETRUE signal at S_SetMode as an error. In such cases, switch S_SetMode to SAFEFALSE to exit the error state.

ValueDescription
SAFEFALSEManual confirmation of the set operating mode not requested.
Edge SAFEFALSE > SAFETRUEManual confirmation of the operating mode set at S_Mode0 to S_Mode7.
