4.9 Adding a Wireless Device to the Gateway
Each device has a 32-bit serial identifier (SID). To add a
wireless device, this SID is written to the intended SLOT
(two registers at a time) in WDL registers.
Note: The two SLOT ID registers must be written to using
FC = 16 (Write to Multiple Registers) otherwise an error
will be generated. See section 3.0 for more details.
SLOT IDs can only be added one at a time.
For example: If you have sensor 43527 in hand and you
wanted to add this to SLOT 0, you would write the
following.
40101 / 100
0
40102 / 101
43527
To move a wireless device from one slot to another, the
SID of the wireless device only needs to be written to the
new SLOT. The old SLOT will be erased and prepared for
future use.
To delete a wireless device from the list, write a 0,0 into
the SLOT and the device will be erased and the SLOT is
prepared for future use.
When registering the first wireless device, the second LED
will go red signifying there is no wired communication
available, then the third LED will start flashing while the
wireless network resets. Please wait approximately 30
seconds (until all LEDs turn green, signifying a successful
network reset) after registering the first device, before at-
tempting any other tasks.
If the WDL SLOT is written to incorrectly, a “MODBUS IO
error message” is returned.
Please see Ref.3 for more information.
