APPENDIX B GENERAL LOG ITEMS
This appendix describes the log items for Sensor, Relay, Alarm, Security, Administration, Communication
and System. Once enabled messages assigned to its group will be logged on a file in the USB Storage
device. Log files are text files.
The following list of active log files are found in the root directory of the storage device.
• SENSOR.LOG,
• RELAY.LOG,
• ALARM.LOG,
• SYSTEM.LOG,
• ADMIN.LOG,
• SECURITY.LOG,
• COMM.LOG.
Log files are created in the root directory. At the start of each day, the active log files are moved into an
archive folder. The archive folder name identifies the year and month of the archive. For example folder
“2014_02” holds the log files for the month of February, in the year 2014. The log files themselves are
renamed, the three digit extension “.log” is replaced with a two digit day of month value. For example
“RELAY.05” would be the log file “RELAY.LOG” from the fifth day of the month. Lastly, it is recommended
that periodically the USB storage device be backed-up to secure, offline storage to ensure the information
are not lost. For performance reasons, at this time the log files can be removed from the USB storage
device.
Log messages can be displayed on the Printer Port when menu item Log File>Printer is enabled while menu
item Option>Remote is configured for Printer. Additionally these messages can be directed to the LCD
Display or a Telnet Console if the menu item Log File>Display or Log File>Console are enabled.
All log files get timestamps every 10 seconds and will display MODBUS traffic summary every minute.
Additional messages listed in this general group will also appear in all log files.
The TIME message contains the following format:
TIME <YEAR,MONTH,DAY> <24HR:MIN:SEC> Day <1-7=Sun.to Sat.>
The example below indicates a timestamp of Monday Aug 27/2012 at 12:00:17 am:
TIME 2013,8,27 00:00:17 Day 2
The Date and Time Changed message will appear when the date and time is changed from various
sources; Remotely (AMC Manager), from Menu, or from BAS. The Date and Time Changed message
contains the following formats:
Date and Time Changed <Source>
There are five MODBUS channels; 1-4 are for sensors, relays, and analog output devices and channel 5 for
BAS communication. The MB5 summary will appear periodically (every minute) when this channel is active.
The MB (MODBUS) summary message contains the following format:
MB<Channel> TA(s) T:<Total Transactions>,G:<Good Transactions>,B:<Bad Transactions>
The following messages typically appear at start up in all log files and are also described below:
• TIME <Date and Time> AMC-1DB Gas Monitor <Version>
• MAC:<MAC> from FLASH
