88 – Programming Time/Date Events & Actions using DTMF
The Sicon-8 has a battery-backed, real-time clock with memories for 128 individual time/date functions
that we call “events”. The clock/calendar can schedule events up to the year 2068 (Events that repeat
yearly are not effected by the YR2068 limit). Events can be programmed to cause relays to operate.
Simple sequences of relays and pauses can also be triggered by events. We call these functions
“actions”. There are 128 action sequences that can be programmed in the Sicon-8. Events can trigger
actions if the action sequence number equals the event number. For instance, event # 001 can only
cause action sequence 001 to trigger. Event # 001 cannot trigger Action sequence 002 or any other
action, except 001. Although the events and actions are tied together, they were made independently
programmable so that you can change a time/date without having to re-program the action or vice-versa.
There are four main event modes that can be used:
1. One-Shot - An event that takes place only once and is never repeated.
2. Repeating – An event that occurs periodically forever such as something that happens every day at
5pm, or something that happens every hour of every day forever.
3. Specific start & duration – These are events that you program to begin running on a specified date
and time, but that run for a programmed duration. For instance, you might want an event to occur
every day at 7am from March 01 through March 07 of next year, but never again thereafter.
4. Specific start & duration that happens every year – This is an event that is programmed like number 3
above except that it re-occurs every year. For instance, you want to automatically change power at
X-o’clock every day during the month of April, and you want to do this every year, forever.
The most common use of the event scheduler is mode #4, where a station needs to change power and/or
antenna pattern on a specific & re-occurring schedule.
The basic command steps to set up any event is as follows:
Enter system setup: 91
Enter event setup command: 88
Enter 3-digit event number: 001 - 128
Enter setup command:
- Disable event: 0
- Enable event: 1 (You must do steps 2 & 3 before enabling an event. If you try to enable an event that
is not already set up or has expired, your event will be automatically disabled.)
- Set event time: 2 (see "Setting the event time") Setting the event time automatically enables the
event. If you don’t want the event to occur, you must disable it using the 88,###, 0 sequence as
described above.
- Set event action: 3 (go to "Setting the action")
