*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.
• Pressing the [] key will display the next statistics screen showing the
acknowledge failure and lost packet errors.
*Net Stats*
A:00002 L:00003
A = Acknowledge errors occur when the module that a communication command
was sent to did not acknowledge. These errors occur in normally operating
systems.
L = Lost packet errors occur when the system loses a packet it tries to send to a
module because the module is not connected or the communication to the module
has been lost.
Offline User Update
An offline user update will update all offline users and programming to intelligent modules.
This should be performed when programming of the system is completed and all intelligent
modules are online. To enter the offline user update function select [MENU, 4, 8, 1, 6] the
following display explains the screen information and actions that are performed.
• Select the offline update option from the network menu. The display will prompt to
ask if you are sure you want to upload offline users to the modules. If you want to
continue with the offline update press the [ENTER] key, to cancel press the
[MENU] key.
