Y_YA_Execute_ST_Template
This function block is a template which can be used when developing functions/function blocks in Structured text using Execute input and adhere to PLCopen output behavior.
Parameters:
| * | Parameter | Data Type | Description | Default |
|---|---|---|---|---|
| VAR_INPUT | ||||
| B | Execute | BOOL | Upon the rising edge, all other function block inputs are read and the function is initiated. To modify an input, change the value and re-trigger the execute input. | FALSE |
| VAR_OUTPUT | ||||
| B | Done | BOOL | Set high when the commanded action has completed successfully. If another block takes control before the action is completed, the Done output will not be set. This output is reset when Execute goes low. | |
| B | Busy | BOOL | Set high upon the rising edge of the Execute input, and reset when Done, CommandAborted, or Error is true. In the case of a function block with an Enable input, a Busy output indicates the function is operating, but not ready to provide Valid information. (No Error) | |
| B | CommandAborted | BOOL | Set high if motion is aborted by another motion command or MC_Stop. This output is cleared with the same behavior as the Done output. | |
| B | Error | BOOL | Set high if an error has occurred during the execution of the function block. This output is cleared when 'Execute' or 'Enable' goes low. | |
| B | ErrorID | UINT | If Error is true, this output provides the Error ID. This output is reset when 'Execute' or 'Enable' goes low. | |
