Set Discrete Watchdog Data
[cmdchars] = !R
Description
The Set Discrete Watchdog Data command sets output levels for targeted discrete output channels of the addressed FieldPoint module. The output channels will output the specified levels if the watchdog timer expires.
Syntax
!R[positions][wdgData]
Use !o!R for modules with up to 32 channels.
| [positions] | Four ASCII-hex characters specify the targeted channels. A "1" in any bit means that the command stores an output level for the corresponding channel. A zero in any bit means that the corresponding channel is not targeted. If you send !o!R, [positions] must contain eight ASCII-hex characters. |
| [wdgData] | Four ASCII-hex characters specify the levels that targeted channels must output if the bank watchdog timer expires. A "1" in any bit means ON. A zero in any bit means OFF. The command ignores bits corresponding to untargeted channels. If you send !o!R, [wdgData] must contain eight ASCII-hex characters. |

Example
The following command sets watchdog output levels for channels of the FieldPoint module at address 51 (0x33). If the watchdog timer expires, channels 0, 1, 2, and 3 will be turned OFF and channels 4, 5, 6, and 7 will be turned ON.

The following command sets watchdog output levels for channels 0, 14, 24, 25, 28, 29, 30, and 31 of the FieldPoint module at address 34 (0x22). If the watchdog timer expires, channels 0, 14, 25, 28, 29, 30, and 31 will be turned ON and channel 24 will be turned OFF.
