CommandDelete input
This edge-triggered input starts the function block operation.
Data type: SAFEBOOL
Initial value: SAFEFALSE
Connection: Connect this input directly or via additional safety-related functions/function blocks as follows:
- Either with a safety-related Boolean variable whose value SAFETRUE represents the status "delete data set from recipe file".
- Or with a signal from the safety-related application, which represents the request to delete the data set from the recipe file.
This can be a signal of a single upstream safety-related function block or the logical connection of signals of several upstream function blocks.
Constant SAFETRUE or SAFEFALSE values are not permitted.
If the function block is activated (input Activate = TRUE), the possible values at this input lead to the following function block behavior:
| Value | Description |
|---|---|
| SAFETRUE | Request to delete the data set (IDRecipeDataSet) from the recipe file specified at input IDRecipeFile. The data set is locked against modification. The data is then overwritten with the value zero. This may take several Safety PLC cycles.In addition, the modified recipe file is updated with the project CRC of the current project and the serial number of the current Safety PLC.If the command is executed successfully, Done switches to SAFETRUE. |
| SAFEFALSE | No data set delete operation is requested. |
