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 being Alarm one, the
rightmost Alarm 32. You can not choose to save channel information if you have selected not to save Alarm
ID's.
The following example shows what the Alarm log entries look like if this configuration is selected:
1:21:10 PM 10/29/98 00000000000000000000000000000000
1:21:11 PM 10/29/98 01000000000000000000000000000000
1:21:13 PM 10/29/98 11000000000000000000000000000000
1:21:14 PM 10/29/98 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 10/29/98 Alarm-01 (CH1-68.72) 1
1:39:46 PM 10/29/98 Alarm-02 (CH3-68.54) 1
1:40:11 PM 10/29/98 Alarm-01 (CH1-73.22) 0
1:40:12 PM 10/29/98 Alarm-01 (CH1-86.36) 1
1:40:27 PM 10/29/98 Alarm-01 (CH1-71.42) 0
1:41:10 PM 10/29/98 Alarm-01 (CH1-69.98)(CH2-71.24) 0
