Online Programming Procedure
You can make the following changes to your program in the online
programming mode:
insert an instruction
remove an instruction
insert a rung
remove a rung
change an instruction or instruction address
The online programming mode is accessible from the industrial terminal
by pressing the key sequence [SEARCH] 52. The processor module must
be in the run/program mode. The heading, “ON-LINE PROGRAMMING”
appears in the top right- hand corner of the screen highlighted in
reverse video.
You can not enter the following instructions during online programming:
temporary end
MCR
ZCL
JMP
JSR
block transfer read and write
The procedure for online programming in run/program mode is similar to
the procedure for editing in program mode. However, the following three
keys have a special purpose in online programming:
[RECORD}
[CANCEL
COMMAND]
[DATA INIT]
Use the [RECORD] key to enter a change to your program. Once pressed,
the changed program is active.
Use the [CANCEL COMMAND] key to abort any online programming
operation prior to pressing the [RECORD] key. Pressing [CANCEL
COMMAND] restores the ladder diagram display and program logic to its
original state prior to the online programming operation. You can also use
it to terminate the online programming mode.
