How To Programme A Trigger; Pm-Number Addressed Execution; Block-Operation - Philips System 21 Quick Operating Manual

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.
