Lamps
Section 4-6
Frame is set: Only the area in the frame will be lit/flashing.
Frame is not set: The area including the frame will be lit/flashing.
• Controlling the Lamps in Batch
More than one lamp can be lit or flashing in batch by registering those
lamps to the same bit.
Example of Batch Lighting
Set the lamps L1 to L5 to the same bit number.
When a Lamp Is Overlapped with a Memory Table Display
The guide display message for a lamp is a fixed character-string. If you want
to change the lamp guide display according to some condition, overlap the
display area of a numeral memory table entry or character-string memory
table entry with the lamp. However, note that different results will be achieved
depending on the timing of the lighting of the lamp and the updating of the
memory table entry. Bear this in mind when creating the control program.
