- for modes "3" and "7" (time-synchronised output)
By programming SC.A... according to the following table, you can set at which time
points the time-synchronised output issues a pulse:
SC.A... Pulse is output
01:143_0 At the beginning of each month at 0 hrs.
02:143_0 At the beginning of each month at 6 hrs. The day boundary (= month
boundary ) "06:00 hrs." can be changed via the serial interfaces under
the address "2:141".
01:142_0 At the beginning of each day at 0 hrs.
02:142_0 At the beginning of each day at 6 hrs. The day boundary "06:00 hrs."
can be changed via the serial interfaces under the address 2:141.
01:403_0 At the beginning of each hour.
01:402_0 At the beginning of each minute.
04:156_0 At the beginning of each measurement period

The pulse duration can be set individually for each output via the serial interfaces
under the addresses "1:618" to "4:618" as a multiple of 125 ms.
If a mode other than "1" or "3", "3", "5" or "7" is set, SC.A... has no significance.
cp.O1 ... cp.O4 cp value for Outputs 1...4
If the output is programmed as a volume pulse output ( Md.A...= 1 ), the increase in
volume is converted with cp.A... into the number of pulses to be output. The con-
version takes place according to the formula: i = V ž cp.A...
where i: Number of output pulses and V: Volume increase which is to be out-
put as a pulse.
cp.A... therefore states how many pulses are to be output for 1 m
3
.
If a mode other than "1" is set, cp.A... has no significance. This also applies to the
setting "time-synchronised output" (see above), although then cp.A... is displayed
dependent on SC.A... with a time unit.
With a change of the output cp value, the corresponding input buffer is cleared .
(cf. messages "Outp.1 Error" to "Outp.4 Error, page 49).
SpO1 ... SpO4 Status pointer for Outputs 1...4
The status pointers SpO1 ... Sp04 determine which status messages an output
represents which is parameterised as a status or event output.
The display of the status pointer occurs as a short text according to Chapter 3.8
with a following arrow pointing upwards "
-
" (e.g. "I3 Warn.sig."). Here, the symbol
"
-
" indicates that the "signal arrives".
For entry a special numerical display is implemented (e.g. " 08_03:1.1 "), because
a text entry on the device would only be possible with a great deal of effort.
If the output is programmed as status or event output "with active logic"
(
Md.A... = 2 or 9), then Sz.A... sets with which status messages of the momentary
status
®
(3.8) the output is to be switched on. If none of the selected messages is
present, the output remains switched off.
If the output is programmed as status or event output "with inactive logic"
(
Md.A... = 6 or 10), then Sz.A... sets with which status messages of the momentary
status the output is to be switched off. If none of the selected messages is present,
the output remains switched on (!).
In contrast to the status output, an event output is reset automatically after an a d-
justable time to its basic state. This time can be set with WinPADS.
