Diagnostic Messages via Terminal
On boot the terminal window will display several messages detailing the boot up and conguration le load of
the unit, these are summarized below. If you require support on a WTP3 installation it is helpful to have a copy of
the conguration les in use and a log of a system boot to send to the WTP support specialist.
Error Types
Error messages are categorised into four types:
• Info
• Warning
• Critical
• Fatal
Info
General message displayed for information, e.g. software version number
Warning
An indication that a conguration error exists. The error does not need the system to stop, but requires user
attention.
For example, if a conguration le calls for a device that is not visible on the network:
Warning: nmeain.d : Serial Device 15 on CAN Channel 1 does not exist
Critical
An indication that an error exists that requires immediate user attention. Critical errors will not stop the system,
but the system is unlikely to operate correctly until the issue is resolved.
Fatal
Fatal errors will stop the WTP3 application from running. FTP access is normally retained. The user must rectify
the issue to use WTP3.
For example, if the le directory referred to in wtp_cong.d for the user les does not exist:
Fatal : Cong File Path does not exist : mydirectory
Conguration Consistency
At startup the system will attempt to cross reference the cong les for validity, ensuring the user has not:
• called the same COM port in multiple les, using dierent port settings
• called the same COM port in multiple les with dierent functions (e.g compass and GPS)
• assigned multiple analogue inputs to a single variable
In this case the system will output Warning messages to the user, as per the following examples:
Heel1 MHU_A_B Multiple Analogue Denition : 0 1 2
• “heel1” and “mhu_a_b” functions have been congured to the same port (channel 0, device 1, port 2):
