4.10 Verifying Wireless Device Activity
After a device is registered, the SLOT it was registered at
can be verified by reading the WDL. Once the slot is
known, a user can read the WDC [SLOT], WDR [SLOT],
and FRR [SLOT] associated with the wireless device.
If a wireless device is registered, but is not actively
communicating, the ACTIVE coil @ WDC[SLOT] offset 0
will be false.
When a wireless device is actively communicating, the
ACTIVE coil @ WDC[SLOT] offset 0 will be true.
4.11 Viewing Wireless Device Data
(Fast Read Method)
All Wireless Devices have two pieces of commonly useful
data:
1) if a threshold is breached or if the device is in an
exception state
2) the acquired data measurement.
Using the FRR, a user can quickly collect new data
generated by multiple devices registered on the gateway.
The purpose of these registers is to allow for efficient
access to the remote wireless device’s most current data.
When new data is available from any Wireless device the
FRR is updated with the newly reported values. The FRR
will zero itself out if
no new
data is received within a
defined period. The defined period is specified in the
Wireless Device Registers offset 18.
