Description
WACTIVE 1 0 True (1) denotes that the system is
configured sufficiently to
communicate to the sensor.
False (0) denotes that the Wireless
system is not active.
Causes for this include:
- No Registered Sensors.
RST_DEVICE 2 1 Writing True (1) to this coil will force
a device reset and cleans out all
current status. Always read as False
(0).
RST_WNET 3 2 Writing True (1) to this coil will force
a
Wireless Network Reset and reform
the operating network setting based
on CHANM and NETID (in Gateway
Registers). Always read as False (0).
RST_COM 4 3 Writing True (1) to this coil will force
the ADDRESS, COMMODE, and
BAUDRATE to defaults. Always read
as False (0). After setting this coil to
true, a device reset command must
be issued before any of the new
settings will take effect.
