The Options parameter can be used to change the properties of the write command if required by the slave device. Use Function Code 06 instead of Function Code 16 for writes. Check this option for the ODP and ODV products. Use Yaskawa ACCEPT/ENTER. This option must be checked for Yaskawa products. |

| Last Error | The result of the last poll of the associated data address in the slave. The Last Error code can be individually cleared by clicking on this parameter and using the Reset pushbutton. |
| Enable | Can be used to enable/disable the polling of the associated data address in the slave. |
