END_VAR

KLx904_SafetyIn: TwinSAFE telegram sent from a KL1904 or KL2904 to a KL6904. This parameter is doubly linked to SafetyIn in the System Manager (input data of the KLx904).

VAR_OUTPUT

VAR_OUTPUT
    bInput1             : BOOL;
    bInput2             : BOOL;
    bInput3             : BOOL;

    tCycleTime          : TIME;
    bConnectionInRun    : BOOL; 
END_VAR

bInput1: Returns input 1 of a KL1904. If this function block is used for connection to a KL2904, the value is always 0.

bInput2: Returns input 2 of a KL1904. If this function block is used for connection to a KL2904, the value is always 0.

bInput3: Returns input 3 of a KL1904. If this function block is used for connection to a KL2904, the value is always 0.

bInput4: Returns input 4 of a KL1904. If this function block is used for connection to a KL2904, the value is always 0.

tCycleTime: Returns the cycle time in ms for exchanging the TwinSAFE telegram between the devices.

bConnectionInRun: Returns TRUE if there is no error in the connection between the KLx904 and the KL6904.

Example of a call in the FBD:

PROGRAM MAIN
VAR
    fbTwinSAFE_KLx904_input         : FB_TwinSAFE_KLx904_input;
    bInput1_KL1904_S_Address_113    : BOOL;
    bInput2_KL1904_S_Address_113    : BOOL;
    bInput3_KL1904_S_Address_113    : BOOL;
    bInput4_KL1904_S_Address_113    : BOOL;
    tCycleTime_KL1904_KL6904        : TIME;
    bConnection3_In_Run             : BOOL;
END_VAR

In the example the values of the KL1904 input data are written to the connected variables. If the output bConnectionInRun is FALSE, all outputs are set to FALSE.

To link the input data, select the parameter KLx904_SafetyIn and select "Modify link..." from the context menu.

and select the corresponding SafetyIn variable in the dialog that follows.
