IOF_SER_SaveFlash
The IOF_SER_SaveFlash function block checks the system parameters located in the DPRAM memory. If no error is present it activates them and saves them in the EEPROM. The function block can adjust system parameters in the EEPROM of the controller to suit the application.
Notice | |
The EEPROM can be re-written up to 100,000 times. The PLC should not automatically activate this function block, but it should be called by the user for specific purposes. |
Inputs
VAR_INPUT
NETID : T_AmsNetId;
DEVICEID : UDINT;
SAVE : BOOL;
TMOUT : TIME := DEFAULT_ADS_TIMEOUT;
END_VARName | Type | Description |
|---|---|---|
NETID | T_AmsNetId | The network address of the TwinCAT computer on which the ADS command is to be executed can be specified here. For the local computer an empty string may be specified. |
DEVICEID | UDINT | The DeviceId is used to specify the SERCOS master whose system parameters are to be stored. The device IDs are specified by the TwinCAT system during the hardware configuration. |
SAVE | BOOL | The function block is enabled by a positive edge at this input. |
TMOUT | TIME | Specifies the time-out period that must not be exceeded when the command is executed. |
Outputs
VAR_OUTPUT
BUSY : BOOL;
ERR : BOOL;
ERRID : UDINT;
END_VARName | Type | Description |
|---|---|---|
BUSY | BOOL | When the function block is enabled, this output is set and remains set until a feedback is received. |
ERR | BOOL | If an error should occur during the transfer of the command, then this output is set once the BUSY output was reset. |
ERRID | UDINT | Returns the ADS error number when the ERR output is set. |
