Programmable messages
Certain information that appears on the display while programs are being
executed could be of special interest to the operator of the machine.
With the code MSG("character chain") a message can be programmed
such that it will appear on the screen while the program progresses.
Example:
N10 G18 G54 G64 LIMS=3000
N20 G00 X200 Z300
N30 MSG("Caution, jump to finishing operation!")
N40 GOTOF LBL18
N50 T1
N60 G96 S160 F0.2 M4 D1
N70 G00 X82 Z0.2 M8
N80 G01 X-1.6
N90 Z2
N100 G00 X200 Z300
N110 LBL18:
N120 T2
N130 G96 S200 F0.15 M4 D1
N140 G00 G42 X0 Z2 M8
N150 G01 Z0
N160 X78 CHR=1
N170 Z-20
N180 X82
N190 G00 G40 X200 Z300
N200 M30
The message programmed in block N30 will be displayed as shown below
(Monitor extract).
The display will remain until a newly programmed message replaces it or
the existing one is cancelled.
The message can be cleared using the code "MSG("")" or by means of the
end of program M30.
