Init and reboot

If the screen displays a message that the update process could not start this is because another network
function has taken priority. When this is completed try to perform the update again.
Each module will be programmed with the configuration information and then reset so that the information is
loaded in to the module. The keypad that is currently being used will eventually be reset and the display will
inform the user that this is taking place.
Module Network Statistics
The module network logs an abundant number of statistics that can be used for fault diagnostics and network
performance analysis. The information below may be requested by support staff to help diagnose potential
problems. To select the network statistics menu select [MENU, 4, 8, 1, 5] the following display explains the
screen information and actions that are performed.
• When the menu item is selected the first statistics will be displayed. To move to the next display press [],
to cancel press the [MENU] key. The first screen will show the network receive and transmit octet count.
*Net Stats*
R:34620 T:78265
R = Received number of octets (8 Bit communication bytes)
T = Transmitted number of octets (8 Bit communication bytes)
• Pressing the [] key will display the next statistics screen showing the overrun and break error counts.
*Net Stats*
O:00000 B:00003
O = Overrun errors occur when the system is heavily loaded and are a normal part of operation. However
the number of overrun errors should not be large in comparison to receive and transmit numbers.
B = Break detect errors occur when the system detects that a device has held the line in a locked state for
longer than the allowable time. This is also part of normal operation.
• Pressing the [] key will display the next statistics screen showing the parity and framing error counts.
*Net Stats*
Z:00000 F:00027
Z = Parity errors should not normally occur during normal operation however they may occur and do not
affect the system.
F = Framing errors will occur during normal operation and do not affect the performance of the system or
how the system operates.
• Pressing the [] key will display the next statistics screen showing the process related communication get
and post functions. These relate to internal tasks that pass the information on the module network to other
parts of the Protege Operating System.
*Net Stats*
G:00000 P:00003
G = Get errors occur when the system is heavily loaded and the available free memory for the
communication receive function becomes exhausted. This can occur normally but should not have high
values in most cases this should always be 0.
P = Post errors occur when the system is heavily loaded and the available free memory for the
communication send function becomes exhausted. This can occur normally but should not have high values
in most cases this should always be 0.
• Pressing the [] key will display the next statistics screen showing the checksum and general UART
(Universal Asynchronous Receiver and Transmitter) errors.
*Net Stats*
C:00000 U:00021
C = Checksum errors occur when a packet sent does not contain a valid checksum. This can occur
frequently depending on the environment and network loading.
U = UART errors occur in normal operation and are the accumulated value of all the individual UART errors.
