| local or remote | 0 à 1 | locked
| locked | 1 à 0 | remote
| Example: From local to remote: 0 à 1, 1 à 0 |  |
5 | Plasma Mode On | 0 = No Action 1 = Turn Plasma Mode ON if previously this bit was 0 |  |
6 | Plasma Mode Off | 0 = No Action 1 = Turn Plasma Mode OFF if previously this bit was 0 Bits 5 and 6 are in collision. Therefore the bit 6 has higher priority than the bit 5. |  |
