Wakeup After the Operator Manually Tells the Gateway to Enter Deep Sleep
Because the Gateway is aware that they system was placed in Deep Sleep mode prior to
power-down, the Gateway will expect the Remotes to take additional time to report in.
1. Power up the Gateway.
2. Immediately after power up, the Form-
C output will be connected between „COM &
NO‟.
3.
As the Remotes report in, the individual bits in the „Remote Status‟ register (register
25) will change state from „1‟ to „0‟. Each bit in this register maps directly to a
Remote in the network.
4. If all Remotes report in within ten minutes, the Form-C output will change state to
connect between „COM & NC‟. MODBUS register 91 will read a value of zero.
5. If all Remotes do not
report in within ten minutes, the FET LED‟s will illuminate and
the FET‟s Outputs will short to ground. You can review the „Remote Status‟ register
(see step 3 above) to determine which Remote(s) did not report in as expected.
Wakeup After the Remotes Automatically Enter Deep Sleep
Because the Gateway is not aware that they system was placed in Deep Sleep mode, it is
likely that the Gateway will indicate a problem after the 75 second boot-up timeout. This
occurs because the remotes are in a Deep Sleep state and will not send a heartbeat
frequently enough to prevent this from happening.
1. Power up the Gateway.
2. Immediately after power up, the Form-
C output will be connected between „COM &
NO‟.
3.
As the Remotes report in, the individual bits in the „Remote Status‟ register (register
25) will change state from „1‟ to „0‟. Each bit in this register maps directly to a
Remote in the network.
4. If all Remotes report in within 75 seconds, the Form-C output will change state to
connect between „COM & NC‟. MODBUS register 91 will read a value of zero.
5.
If all Remotes do not report in within 75 seconds, the FET LED‟s will illuminate and
the FET‟s Outputs will short to ground. You can review the „Remote Status‟ register
(see step 3 above) to determine which Remote(s) did not report in as expected.
6. After any Remotes report in, MODBUS register 91should read a value of 2222. This
indicates that the Remotes entered Deep Sleep without being told to by the
Gateway. After all Remotes report in, register 91 should read a value of zero.
