F-periphery data component of the safety card
When compiling the configuration tool (HW Config), the system automatically generates an F‑periphery data component (DB) for each safety card. The F‑periphery DB offers users an interface in which they can evaluate or control variables in the safety program.
The symbolic name consists of the invariable prefix "F", the start address of the F-periphery, and the name entered in the object properties during configuration for the F-periphery (e.g.: F00008_198).
The following table shows the F‑periphery DB of the safety card:
Address | Symbolic name (variable) | Data type | Function | Presetting | |
|---|---|---|---|---|---|
Variables that the user can control. | DBX0.0 | "F00008_198" (PASS_ON) | BOOL | 1: Activate passivation | 0 |
DBX0.1 | "F00008_198" (ACK_NEC) | BOOL | 1: Acknowledgment required for reintegration of the safety card | 1 | |
DBX0.2 | "F00008_198" (ACK_REI) | BOOL | 1: Acknowledgment for reintegration | 0 | |
DBX0.3 | "F00008_198" (IPAR_EN) | BOOL | Variable for reparameterization (not supported by the safety card) | 0 | |
Variables that the user can read. | DBX2.0 | "F00008_198" (PASS-OUT) | BOOL | Run passivation | 1 |
DBX2.1 | "F00008_198" (QBAD) | BOOL | 1: Substitute values are output | 1 | |
DBX2.2 | "F00008_198" (ACK_REQ) | BOOL | 1: Acknowledgment required for reintegration | 0 | |
DBX2.3 | "F00008_198" (IPAR_OK) | BOOL | Variable for reparameterization (not supported by the safety card) | 0 | |
DBB3 | "F00008_198" (DIAG) | BYTE | Service information | - |
PASS_ON
With the PASS_ON variable, you can activate a passivation of the safety card. Passivation of the F-periphery takes place, provided that PASS_ON = "1".
ACK_NEC
After resolving a fault, the safety card is reintegrated depending on the setting of the variable ACK_NEC.
- ACK_NEC = 0: Automatic reintegration.
- ACK_NEC = 1: Automatic reintegration following acknowledgment by the user.
WARNING
Impermissible parameterization of the variable ACK_NEC = 0.
Severe or fatal injuries.
- The parameterization of the variable ACK_NEC = 0 is permitted only if automatic reintegration is safe for the respective process.
- Check if automatic reintegration is permitted for the respective process.
ACK_REI
In order to reintegrate the safety card after the fault has been corrected, user acknowledgment with positive edge at the variable ACK_REI is required. Acknowledgment is only possible if variable ACK_REQ = 1.
ACK_REQ
The F-control system sets ACK_REQ = 1 after all faults in the data exchange with the safety card have been corrected. After successful acknowledgment, the F-control system sets ACK_REQ to "0".
PASS_OUT
The variable PASS_OUT indicates whether there is a passivation of the safety card. Substitute values are output.
QBAD
Error in the data exchange with the safety card. Indicates passivation. Substitute values are output.
DIAG
For service information purposes, the variable DIAG supplies non-failsafe information about faults that have occurred in the F‑control system. For further information, refer to the relevant F‑control system manual.
