13. Scheduled Actions


Scheduled Actions are generally used to retrieve data or to perform a "wellness" check according to a user-defined time table.  Typically, the NetLink II will contact your PC at the scheduled time and day, and then automatically download collected data. Note that in addition to the Scheduled Actions described in this section, you can also schedule the unit to regularly perform a Push action, as described in Section 5.4.6.

NetLink II allows a great deal of flexibility in configuration of the Scheduled Action feature.  The unit can perform any of the following actions according to the user-defined schedule:

•                      Callout: NetLink II will contact a remote PC via modem, and execute a series of user-defined commands.  Although these commands are usually employed to download data, they can also report memory conditions, alarm status, and etc.

•                      Page:  NetLink II will dial an alphanumeric pager and send a user-defined message. This allows NetLink II to perform a wellness check, or inform system managers that the unit is operating properly.

•                      SNMP Trap:  NetLink II will send an SNMP Trap to a network manager.  This option can also be used to perform a wellness check, or notify personnel that it is time to check the unit.

•                      Console Port: NetLink II will contact the device connected to its Console Port in order to download data or report status.

•                      Email / Text Message: NetLink II will send a text message or email to a user defined address.


Each of the two available schedules allow up to seven scheduled actions per week. This provides a total of fourteen events per week. For more information on these actions, please refer to Section 12.

Figure 13.1:  Scheduled Action Configuration Menu (Schedule 1 Shown)

To access the Scheduled Action configuration menus from the Main Menu, type 24and press [Enter], a selection menu will be displayed. Next, type 1for Schedule 1, or 2for Schedule 2, and press [Enter]. Both configuration menus include the following:


1. Scheduled Action:  Enables/disables the Scheduled Action function.  Note that in addition to enabling the schedule, the user must also define the schedule and specify the action that will be performed according to schedule.

2-8. Daily Schedules: Defines the time that the action will be performed on each day of the week. Time values are entered in 24-hour (Military) format.


11. Add Exclusion: Defines dates (such as holidays) when the Scheduled Action will not be performed. As each exclusion is defined, it will be added to the display above item 11.

12. Delete Exclusion: Deletes a date from the exclusion list.


Alarm Action Parameters:

21. Action: Defines the type of event that will occur according to the schedule. The user may select None, Callout, Alphanumeric Page, Numeric Page, SNMP Trap, Email/Text Message, or Console. 

22. Phone #: Defines the phone number that will be dialed for a scheduled Callout or Page. This is the number for your remote modem or pager service.

Note:  For Numeric Paging only, this prompt can specify both a pager phone number and a numeric "message". In this case, the phone number is entered using the following format:


Where PHONENO is the pager number, and MESSAGENO is any number which will notify the user that a scheduled page has occurred. For example, to dial 555-1212 and send the message "999", the phone number would be defined as "5551212@999#".

23. Pager ID 1: The first Pager ID Number used when a scheduled alphanumeric page is performed. NetLink II will dial up to three pagers for each schedule.

24. Pager ID 2: The second Pager ID for this schedule.

25. Pager ID 3: The third Pager ID for this schedule.

26. SNMP Mgmt: The SNMP Manager(s) that will receive SNMP Traps generated by this schedule.  This prompt can select Manager 1, Manager 2, or both. Note that IP addresses for each SNMP Manager are defined via the Network Port Configuration menu.

27. Email/Message To: The email address(es) that will receive email and text messages generated by this schedule when the Email/Text Message action is selected. This item can select either or both of the two email addresses, which are defined via the Network Port Configuration Menu, Item 38 (Section 5.4.5.)

28. Message: Defines the message that will be sent for a Scheduled Callout, Alphanumeric Page, SNMP Trap, Email Action, or Console Action.

29. Auto Execute: When this item is enabled, NetLink II can be scheduled to automatically execute the command string defined under item 30.


30. Execute Commands: The Auto-Execute command string.  This command string consists of a series of NetLink II ^Bxx commands, with each command separated by a backslash character and a forward slash character (e.g., \/04\/01). ^Bxx commands are described in Section 17. For more information on Auto- Execute command strings, please refer to Section 12.3.

When the Scheduled Action feature is used to download data or send a wellness message, the Auto Execute string must be defined in order to specify the exact task to be performed. For example, to instruct the NetLink II to automatically send the Site ID message and then send all alarm records, the Auto Execute string would be defined as "\/03\/01,ALM".


•                      When the Auto-Execute string is defined, commands are entered without the ^B character, and each individual command is separated by a slash character.

•                      In order for the Auto Execute feature to function, item 29 must be enabled, the command string must be defined, and item 21 (Action) must be set to perform a Callout, Email Action or Console action.
