From the Alarm configuration dialog box, you can define the information that will be saved in the
log file. Options include the Time and Date when the state change occurred, the Alarm number, the
Channel(s) that tripped the alarm along with the current reading, and the state of the alarm itself or
all alarms, either 1 or 0. Additionally you can define the character that is used to separate the
information in the file. This is useful if you want to read the file into a program that presents the
information in a tabular format, such as Microsoft Excel.
By using combinations of option settings you can define how the alarm log file is filled. If you
choose not to save Alarm ID's (Alarm numbers) in combination with saving All Alarm States, your
Alarm file will be saved with one line of text each time an Alarm state change is detected during
polling. The line will contain the optional Time and Date and 32 digits, one for each alarm, set to
either 0 or 1. The left most digit is Alarm one and the rightmost is Alarm 32. Note that you cannot
choose to save channel information if you have not checked the Alarm ID's checkbox.
The following example shows what the Alarm log entries look like if this configuration is selected:
1:21:10 PM 01/29/03 00000000000000000000000000000000
1:21:11 PM 01/29/03 01000000000000000000000000000000
1:21:13 PM 01/29/03 11000000000000000000000000000000
1:21:14 PM 01/29/03 00000000000000000000000000000000
If you choose to log Alarm ID's and multiple Alarm state changes are detected during a single poll,
multiple lines of text will be saved in the log file; one for each alarm that had a state change. By
examining the optional Time and Date information you can identify which lines in the Alarm log are
associated with Alarms that were detected during a specific polling event. If you have Alarm ID's
enabled, you can also choose to log Channel information. The channel information contains the channel
label and the current reading associated with the channel. The following example shows what the alarm
log entries look like if this configuration is selected:
1:39:46 PM 01/29/03 Alarm-01 (CH1-68.72) 1
1:39:46 PM 01/29/03 Alarm-02 (CH3-68.54) 1
1:40:11 PM 01/29/03 Alarm-01 (CH1-73.22) 0
1:40:12 PM 01/29/03 Alarm-01 (CH1-86.36) 1
1:40:27 PM 01/29/03 Alarm-01 (CH1-71.42) 0
1:41:10 PM 01/29/03 Alarm-01 (CH1-69.98)(CH2-71.24) 0
