State the Problem
The device has failed to
write to the database
memory. Any data
written during this
time may have been
lost
Either the host has not
delivered a discrete
command with in the
fault state time, or the
delivered discrete com-
mand from the host in-
dicates a bad status.
The device is in simula-
tion mode and may not
be reporting actual in-
formation.
The device is operating
in a high power mode.
This is not recommen-
ded for this device.
Diagnostics and troubleshooting
Recommended Ac- Associated Device
tions Status Bits
1. Reset the device. 2. Byte 0; bit 2
If logging dynamic da-
ta is not needed, this
advisory can be safely
ignored. 3. If the con-
dition persists, replace
the transmitter.
1. Verify that the dis- Byte 1, Bit 0
crete control host is
on line and sending
discrete commands. 2.
Ensure that the dis-
crete control host is
sending commands at
least once within the
fault state time (fault
state time can be ad-
justed to meet the
needs of the applica-
tion). 3. Verify that the
discrete control host is
sending commands
with good status . 4. If
the condition persists,
replace the transmit-
ter.
1. Verify that simula- Byte 8; bit 0
tion is no longer re-
quired. 2. Disable Sim-
ulation Mode in Serv-
ice Tools. 3. Reset the
device.
1. Disable high power Byte 2; bit 7 only if de-
mode. vice_powerMode == 1
