FB_CreateGUID
The function block generates a new GUID. It is possible to get a list of different new GUIDs with one call if an array of type GUID is specified as buffer at the input.
Inputs
VAR_INPUT
bExecute : BOOL;
sNetId : T_AmsNetId;
tTimeout : TIME := DEFAULT_ADS_TIMEOUT;
pGuidBuffer : POINTER TO GUID;
nGuidBufferSize : UDINT;
END_VAR
Name | Type | Description |
|---|---|---|
bExecute | BOOL | The function block is activated by a rising edge at this input. |
sNetId | T_AmsNetId | String containing the AMS network ID of the target device to which the ADS command is addressed (type: T_AmsNetId). |
tTimeout | TIME | States the length of the timeout that may not be exceeded by execution of the ADS command. |
pGuidBuffer | POINTER TO GUID | Indicates the address to the buffer for generated GUIDs. It is possible to specify the address on an ARRAY OF GUID. |
nGuidBufferSize | UDINT | Indicates the size in bytes of the specified buffer. |
Outputs
VAR_OUTPUT
bBusy : BOOL;
bError : BOOL;
nErrorId : UDINT;
END_VAR
Name | Type | Description |
|---|---|---|
bBusy | BOOL | When the function block is activated, this output is set to TRUE and remains set until feedback is received. As long as bBusy is TRUE, no new command can be executed. |
bError | BOOL | If an error occurs during command execution, this output is set, once the bBusy output has been reset. |
nErrorId | UDINT | In the event of a set bError output returns the ADS error code. |
