FB_DALIV2FileLogging
The function block FB_DALIV2FileLogging reads the FIFO buffers written in the function blocks FB_DALIV2EmergencyLightingFT and FB_DALIV2EmergencyLightingDT (IN-OUT variable fbStringRingBuffer) and writes the contents to a log file.
Inputs
VAR_INPUT
bStart : BOOL;
sPathName : STRING;
sNetId : STRING;
END_VARName | Type | Description |
|---|---|---|
bStart | BOOL | The function block is activated by a positive edge at this input. |
sPathName | STRING | Contains the path and file name for the buffer file to be opened |
sNetId | STRING | A string containing the network address of the TwinCAT computer where the buffer file is to be written or read can be specified here. For the local computer an empty string may be specified. |
 | sPathName: The path can only point to the local file system on the computer. This means that network paths cannot be specified here. |
Inputs/outputs
VAR_IN_OUT
fbStringRingBuffer : FB_MemRingBuffer;
END_VARName | Type | Description |
|---|---|---|
fbStringRingBuffer | FB_MemRingBuffer | Reference to the FIFO buffer in which the log entries are stored. |
Outputs
VAR_OUT
bBusy : BOOL;
bError : BOOL;
nErrorId : UDINT;
END_VARName | Type | Description |
|---|---|---|
bBusy | BOOL | When the function block is activated this output is set and remains set until the log buffer is cleared. |
bError | BOOL | If an ADS error should occur during the transmission into the log file, then this output is set after the output bBusy has been reset. |
nErrId | UDINT | Supplies the ADS error number or the command-specific error code (see error codes) when the output bError is set. |
Requirements
Development Environment | PLC library to include |
|---|---|
TwinCAT from v3.1.4020.14 | Tc2_DALI from v3.4.3.0 |
