Inputs:
| Name of Function Block | A local tag that references the name of the Function Block. |
| ExtInputs | These are the input IO mapping. |
| ExtOutputs | These are the output IO mapping. |
| Start | This is the input that starts the Function Block. |
Outputs:
| InCycle | BOOL output bit that indicates the status of execution of the Function Block. If this is high, then the Function Block is executing. |
| Done | BOOL output bit that indicates the status of completion of the Function Block. If this is high, then the Function Block execution is complete. |
| Error | BOOL output bit that indicates if an error occurred during execution. |
| ErrCode1 and ErrCode2 | INT error codes from the robot controller. These should be 0 in normal operation, and one or both are greater than 0 when the Error bit is high. |
Function Blocks have additional inputs and/or outputs. These are described separately for each Function Block in the following:
