RTC Action/Message Qualifi er Parameters (P3605-P3608)
Qualifi er parameters shown in Table 12-4 set the interval of time of the actions and messages selected.

DESCRIPTION
0
Once
Action/Message is scheduled once to occur on the date and time entered.
1
Second
Action/Message is scheduled every second. Starting on the date and time entered and
repeated every second thereafter.
2
Minute
Action/Message is scheduled every minute. Starting on the date and time entered and
repeated every minute thereafter at the same seconds into the minute specifi ed in the start
date and time.
3
Hourly
Action/Message is scheduled hourly. Starting on the date and time entered and repeated
every hour thereafter at the same minutes and seconds into the hour as specifi ed in the start
date and time.
4
Daily
Action/Message is scheduled Daily. Starting on the date and time entered and repeated every
day thereafter at the same hour, minutes and seconds specifi ed in the start date and time. If
the day specifi ed does not exist for that month the action/message is skipped.
5
Monthly
Action/Message is scheduled monthly. Starting on the date and time entered and repeated
every month thereafter on the same day, hour, minutes and seconds specifi ed in the start
date and time.
6
Yearly
Action/Message is scheduled yearly. Starting on the date and time entered and repeated
every year thereafter on the same month, day, hour, minutes and seconds in the start date
and time.
RTC Schedule Date Parameters (P3609-P3612)
To each action and message there is an associated start date and time. For Action 1 (P3609) is used; for Action 2 (P3610)
and for Messages 1 & 2 (P3611 and P3612) are used respectively.
The internal date and time parameter format is shown in Table 12-5 .

RTC Counter and Maximum Count Parameters (P107 and P3630)
Monitor parameter P107 is a general purpose RTC Counter that can be assigned as the target of a RTC action. This
parameter may be incremented, decremented or reset by RTC actions.
Parameter number P3630 sets the maximum for P107, so that: -P3630 ≤ P107 ≤ P3630.
The comparators A&B of the PLC Operating Mode along with the Composite Reference make use of the maximum setting of
a parameter for internal scaling of their operations.
RTC Daylight Saving Time Parameter (P3631)
P3631 has three settings: OFF, U.S.A. (United States of America) and E.U. (European Union).
Setting it to OFF disables the DST Feature. Setting it to USA enable Daylight Saving Time for US customers. Setting it to EU
enables Daylight Saving Time for Europe based countries.
Power Cycles and RTC Edit Changes
The RTC acts like an alarm clock during power cycles, edit changes and DST (Daylight Saving Time) updates. After power
up, even though an action/message would have occurred during the power down period no action/message is issued, that
action/message is lost. The next regularly scheduled action/message will trigger on the next regularly occurring clock edge
after power up.
Likewise if the RTC is advanced by some time-offset due to editing or DST action/messages may be lost. For example,
digital output 1 is scheduled to turn on at 1:00 PM daily. At 12:15:00 PM the clock is changed to 1:15:00 PM advancing it an
hour.
The output will not turn on that day since its triggering edge never occurs.
On the other hand, if the clock is receded by one hour, that is, changed at 1:30:00 PM to 12:30:00 PM then two triggers for
digital output 1 on will have been generated that day since the RTC will have passed through 1:00 PM twice. Furthermore,
if an active RTC message is not acknowledged by an operator and power is cycled that message persists after the cycle.
The operator must acknowledge an RTC message even if power is cycled. The same is NOT true for outputs. RTC controlled
digital outputs and relays are reset at power up.
