neoECU devices also have a sleep mode. Sleep mode can be enabled in Function Block scripts using the Sleep step command. Table 1 gives an example Function Block script to enable sleep mode. This script works by checking the present status of a message. If the message is not received when it is expected, the device will go to sleep. When normal traffic is received again, the neoECU will wakeup again.
Table 1: Example Function Block for enabling sleep mode
| Step | Description | Value | Comment | |
|---|---|---|---|---|
| 1 |  | Set Value | Message Present = 0 | Clear the Present flag of a Periodic message normally on the bus |
| 2 |  | Wait for | 2 Second | Wait twice as long as normal periodic duration of the message |
| 3 |  | Jump If | Message Present To Step 1 | Jump to Step 1 if the message is present |
| 4 |  | Sleep | If not present, go into sleep mode | |
| 5 | | Jump to | Step 1 | When device wakes up, go to step 1 |
For more information on Function Block scripts see Vehicle Spy 3's help documentation. Sleep mode examples are included in the examples section for each neoECU device.
