21. Set Date (V)
The letter V is the command
to set the date. The format for
the set date command
is as follows:
Vmm:dd (American)
Vdd:mm (International)
Programming Example
-
Enter the following
statements
into
the HP-85 to program the date for July 12th.
REMOTE 717 (END LINE)
OUTPUT 717; "'/12:07X"
(END LINE)
OUTPUT 717; "D2X" (END LINE)
When END LINE is pressed the second time, the Model 705 sets
the date for July 12th in International
format when the END LINE
key is pressed
the third time
the date
is displayed
on the
Model 705. For American format the second statement
would be:
OUTPUT 717; "VO7:12X" (END LINE)
The date (American
or International)
must appear
in the state-
ment as a four digit number. If three digits are used instead of
four the Model 705 moves the three digits to the right by one
place. For example, enter the following statement
into the HP-85.
OUTPUT 717; "V123X" (END LINE)
When the END LINE key is pressed
the date is set to 01.23
which is January 23rd in the American format. If two or less digits
are used instead of four digits the Model 705 displays an IDDCO
(Illegal
Device
Dependent
Command
Option)
and does
not
change the present date. The colon between
the month and day
in the statement
is optional.
22. Set Interval Time (IV)
The letter W is the command
to set the interval time in sec-
onds. The maximum
interval
time is the programmed
time
for the channel to be closed. The format for the interval time
command
is as follows:
Wnnn.nnn
where
W = Set Interval Time Command
n = Number of Seconds
Programming Example
-
Enter the following
statements
into
the HP-85 to program the interval time to three seconds.
REMOTE 717 (END LINE)
OUTPUT 717; "WOO3.OOOX" (END LINE)
When
the END LINE
key is pressed
the second
time,
the
Model 705 sets the interval time to three seconds. To verify that
the interval time has been set to three seconds send a Dl com-
mand. This is the command to display the interval time.
In the second
statement
the leading
and trailing
zeroes
are
optional. As long as the decimal point is entered in the appropri-
ate place the leading and trailing zeroes are optional. The inter-
val time format on the Model 705 display is always six digits.
23. Programmable Terminator (Y)
The Model 705 uses special terminator
characters
to mark
the end of its data string. To allow a wide variety of control-
ler's to be used, the terminator
can be changed
by sending
the appropriate
command
over the bus. For more informa-
tion and a programming
example
refer to paragraph
3.5.7.
24. Alternate Outputs (U)
The letter U is the command
to program the Model 705 to
transmit the status word, settling time, alarm time, interval
uo-
Ul
u2
-
-
u3-
u4-
u5-
U6
u7
-
-
Sending the UO command
outputs the present chan-
nel number. The present channel number can be sent
with or without a prefix depending
on the present pre-
fix mode (G). Refer to the flowchart
in Figure 3-6 for
the sequence
of sending the U and G modes. Refer
to paragraph
3.5.8 step 7 for information
concerning
the prefix modes and their formats.
Sending
the Ul command
outputs
all the channel
numbers. All the channel
numbers can be sent with
or without a prefix depending
on the present prefix
mode (G). Refer to the flowchart
in Figure 3-6 for the
sequence
of sending the U and G modes. Refer to
paragraph
3.5.8 step 7 for information
concerning
the
prefix modes and their formats.
Sending the U2 command
outputs the digital I/O port
status. The digital I/O port status can be sent with or
without
a prefix
depending
on the present
prefix
mode (G). Refer to the flowchart
in Figure 3-6 for the
sequence
of sending the U and G modes. Refer to
paragraph
3.5.8 step 7 for information
concerning
the
prefix modes and their formats.
Sending the U3 command
outputs the time and date.
The time and date can be sent with or without a prefix
depending
on the present prefix mode (G). Refer to
the flowchart
in Figure 3-6 for the sequence of send-
ing the U and G modes. Refer to paragraph
3.5.8
step 7 for information
concerning
the prefix modes
and their formats.
Sending the U4 command
outputs the status word.
The status word can be sent with or without a prefix
depending
on the present prefix mode (G). Refer to
the flowchart
in Figure 3-6 for the sequence
of send-
ing the U and G modes. Refer to paragraph
3.5.8
step 7 for information
concerning
the prefix modes
and their formats.
Sending the U5 command
outputs the channel set-
tling time. The channel settling time can be sent with
or without
a prefix depending
on the present
prefix
mode (G). Refer to the flowchart
in Figure 3-6 for the
sequence
of sending the U and G modes. Refer to
paragraph 3.5.8 step 7 for information
concerning
the
prefix modes and their formats.
Sending
the U6 command
outputs
the alarm time.
The alarm time can be sent with or without a prefix
depending
on the present prefix mode (G). Refer to
the flowchart
in Figure 3-6 for the sequence of send-
ing the U and G modes. Refer to paragraph
3.5.8
step 7 for information
concerning
the prefix modes
and their formats.
Sending the U7 command
outputs the interval time.
The interval time can be sent with or without a prefix
depending
on the present prefix mode (G). Refer to
the flowchart
in Figure 3-6 for the sequence of send-
ing the U and G modes. Refer to paragraph
3.5.8
step 7 for information
concerning
the prefix modes
and their formats.
time or first/last channel data on talk. The alternate
outputs
can also transmit the U commands
with or without a prefix.
The commands
are as follows:
3-22
