A
Default CPU set to CPUB
The default view for the HMI has been set to
CPU A
Messnger Commission
Command Sent for Breaker
[Name]
Logged when a command to commission an
Entelliguard Messenger is issued to a CPU
Messnger Decommission
Command Sent for Breaker
[Name]
Logged when a command to decommission
an Entelliguard Messenger is issued to a CPU
Frequency Set To [50/60]Hz for
[CPUA/B]
Logged to record a change in the frequency
setting for a given CPU
Caution: Settings Failed Writing
Frequency to [CPUA/B]
Logged to indicate that a request to change
the system frequency of a given CPU was
rejected
Also check the event log for communication
errors within the general time frame in which
this event occurred. See the communications
troubleshooting tips above if this is the case
(
Troubleshooting communications between
an HMI and a CPU: on page 241
).
Caution: Settings Failed Writing
Commission Status To [CPUA/B]
Logged to indicate that a request to change
the commissioning status of a given CPU was
rejected
Also check the event log for communication
errors within the general time frame in which
this event occurred. See the communications
troubleshooting tips above if this is the case
(
Troubleshooting communications between
an HMI and a CPU: on page 241
).
Attention: System Freq
[50/60]Hz While CPU Synch
Clock Freq [60/50]Hz
Indicates a discrepancy between the
frequency jumper setting on the Hardware
CPU sync clock in the CPU chassis and the
firmware setting in the HMI / CPU
Verify that the jumper on the CPU synch clock
is set to the same system frequency as the
software setting.
Caution: CPUA and CPUB have
duplicate IDs
Both CPUs are given the same designation (A
and or B).
Contact GE Post Sales Service immediately
(see
). Certain
control schemes and advanced features of
Entellisys will not function in this state.
Caution: Invalid ID for CPUA.
Expecting ID 0
The designation in the CPU firmware does
not match the designation assigned to that
CPU in the HMI.
Verify that the IP addresses for each CPU are
not reversed with respect to their A and B
designations.
Caution: Invalid ID for CPUB.
Expecting ID 1
The designation in the CPU firmware does
not match the designation assigned to that
CPU in the HMI.
Verify that the IP addresses for each CPU are
not reversed with respect to their A and B
designations.
Attn:Settings Discrepancy btwn
CPUA & CPUB. Updt in
Maintenance-Settings Menu
The settings are not consistent between the
primary and redundant CPUs and require
synchronization.
Open the Settings File tab under the
Maintenance dialog box to synchronize the
settings files. Note that a sufficient privilege
level is required to perform this action.
Caution: Option Mismatch
between CPUA and CPUB. Retry
The available options programming is not
consistent between the primary and
redundant CPUs.
Contact GE Post Sales Service (see
).
