8.6. HOW
TO
PROGRAMME A TRIGGER
(impulse
on the trigger-line of the System
21
bus)
This can be done with
System
21
master command
"
AID;XCU~T
"
or
IEEE-bus command GET (Group Execute Trigger)
Examples:
Using on P2000C
on HP85
master command
IEC
PRINT
#11
,
"AID
;
XCU~T
"
OUTPUT
711
;
"
AID
;
XCU~T
"
IEEE command GET
IEC
TRIGGER #
11
TRIGGER
711
8.7. PM-NUMBER ADDRESSED EXECUTION
When only a group of identical units have to receive an execute command this can
be done by the command
"AID;XCU nn" addressed to the master (see also 8.9.
"Scan Function").
"nn"
stands for the last two digits of the slaves type number. This
execution command
is
independent of execution mode setting.
Example:
"AID;
XCU
20"
All PM
2120
units will execute their received commands (also initiate
commands), independent
on
the execution modes selected.
8.8. BLOCK OPERATION
10
Block operation is the sequential execution of functional commands stored on
successive positions
at
the block-memory, always starting with position 0 (serial
recall
from memory; see also
8.4).
Block operation is initiated
by
command "AIDnnn;
I~B
[,n)". The section enclosed within ( ] is optional.
"n"
represents
an
integer
value 0 ..........
19
indicating the last block-memory position to be executed. Omitting
the
value "n", the default value will be
19.
After that, execution can be performed
step by step by giving
"X"
or a trigger command, depending
on
the execution mode
selected,
or
a PM-number addressed execution command (see
8.7.).
The Execute
Unconditional mode is not allowed for block operation. "Block operation, once
initiated, may
only be followed by execution commands or request commands
(commands with
"?")
. All other commands will cancel block operation.
