When a message times out, a message log file is created. This means that the message has not been sent successfully. Also, the system has reached the configured number of times for the system in sending the message again. The data that is written to the file is one of the following Trimble Mincom Aquila Caterpillar (TMAC ) structures:
- "tmacm_req_desc_t"
- "tmacm_msg_desc_t"
This structure is followed by the user data portion of the message.
A timer function on the onboard system periodically checks for the existence of the message log file. The frequency of this check is determined by the "$ Message Log File Interval" configuration key. The following sequence of internal messaging occurs after the creation of the message log file:
- The message times out.
- Message log file is created.
- Timer function checks for the existence of file.
- If timer function finds the file, a file status message is sent to the office.
- The office receives the file status message. Then, a file action message is sent to the onboard system to deactivate the file. Then, the onboard system will stop writing to the message log file.
- Fleet on the monitor display group responds with a file status message. The file status message indicates that the file has been deactivated.
- The office requests the usage of an onboard File Transfer Protocol (FTP) for the file.
- The office deletes the file with the use of the FTP server.
The default route file contains information that allows the onboard system to get a default assignment when an assignment cannot be received from the office. The file may contain the following items:
- A waypoint
- The default destination for that waypoint
- The other destinations for specified types of materials
The destination waypoint for a dump waypoint is a loading machine waypoint. The destination waypoint for a shovel waypoint is a dump waypoint. When the default assignment file is used, the routes that are created consist of two types of waypoints: the current waypoint and the destination waypoint. Waypoints that are between the current waypoint and the destination waypoint are not considered in the default assignment route. The waypoints will not be displayed. Therefore, a route in a default assignment is displayed as a straight line.
The "DiagMsgLogxxx.txt" log file will be recorded in the diagnostic directory that is specified in the configuration file with the "$ Diag Directory" key. Multiple log files will be written so this file is not overwritten on start-up. Before a file is deleted, the number of log files that will be written is specified in the configuration file with the "$ Diag Log File Count =" key. The default value for this key is three. The log file is a Unicode format. The log file can be viewed in Windows NT Notepad or Microsoft Word.

The signal from the horn needs to go to pin 5 on the Digital Input on the health interface module. This signal is a switch to ground on the health interface module and not a 24V input. This digital input wire is Y986-A75-BR(Brown)(pin 5 on the 6-pin Deutsch connector) to signal to Cat® Health Onboard that a "send truck" is required. On the loading tool application, Cat Health Onboard supports the ability to create a "send truck" message through a horn or button press. Also, in the topeconfig.txt for the loading tool, the keys:
- $ Send Truck Input =4
- $ Digital IO Poll Rate =50
Note: The above keys will need to be added.
