RCP (recipe)
The RCP instruction reads the data value of a variable from the recipe data file that resides in the recipe data file folder in the SD card and updates the value to the run-time engine. Writes the variable value with the run-time engine to the recipe data file in the SD card.
Languages supported: Function block diagram, ladder diagram, structured text.
This instruction applies to the L20E, L50E, and L70E controllers.
RCP
Parameter | Parameter Type | Data Type | Description |
|---|---|---|---|
Enable | Input | BOOL | Enable recipe read/write instruction block.
|
RWFlag | Input | BOOL | TRUE: RWFlag (Write operation). Recipe writes the variable's values with the run-time engine into a recipe data file on the SD card. FALSE: RWFlag (Read operation). The recipe reads the variable's values from the SD card and updates the corresponding variable's value to the runtime engine. |
CfgID | Input | USINT | Recipe configuration VA ID number 1-10. |
FileName | Input | STRING | Recipe data file name (maximum 30 characters length). |
Status | Output | USINT | Recipe instruction block current status. RCP status codes:
|
ErrorID | Output | UDINT | The numeric RCP error code. The definitions are defined in RCP error codes. |
