(4) Enter the block number you want to skip
using the numerical keypad (see figure at
right).
Press the number to be set as the block
number and then press the carriage return [CR] to enter the
value.
The display will change accordingly. If 3 is entered “B 3P
(green)” will change to “B 3S (yellow).”
Enter the block skip number one more time to cancel the block
skip flag.
(5) A block skip displayed in red indicates that the block has been
set at the MCS 30 and cannot be changed on the FCP IV-3.
(6) If the user presses the [RETURN] command function key after
all the block skips have been set, the previous screen will
display.
B 1P (green): Placing will be carried out on Block 1.
B 2S (yellow): Block 2 will be skipped. This skip was set at
the machine.
B 3S (red): Block 3 will be skipped. This skip was set in
the MCS/2H program and cannot be cancelled
at the machine.

3.2.2 Setting Automatic Block Skip Marks
In this case, the camera will read the block skip marks on the board
and automatically skip the appropriate blocks.
(1) Mark the board with very large bright (or dark) block skip
marks. Whether the mark is inside or outside each block makes
no difference. Only the number of the block is important.
(2) Enter the mark type, mark color (B/W) and CCD level in the
[Program] Mark_data via the MCS/2H editor, and enter the
mark sizes (Size X, Size Y) and reading threshold level (CCD).
(3) Enter every block number into sequence data (N_data) block
number (B).
(4) Enter the letter B into sequence data (N_data) device type (W).
(5) Enter the Mark_data Mark No. as the device number in
sequence data (N_data).
(6) Finally, enter the XY coordinates for each block skip mark into
sequence data (N_data).
The example below shows the entries for two block skip marks.
Program Data
Mark_data Type Ptn B/W CCD L/S Scan Size_a Size_b Size_c Size x Size_y
001 B 00 B 150 0200 100 000 0050 0100 0100
N_Data B W D X Y Q
001 1 B 001 -500 800 0.00 : Block skip mark 1
002 2 B 001 -1500 800 0.00 : Block skip mark 2
When B is entered in the W column, the machine will automatically
read the block skip marks and skip the boards that are marked
appropriately. Mark sizes (Size X, Size Y) and reading threshold
levels (CCD) can also be set at the machine. See Part 3, Section 3 of
this manual for further details.

3.3 Block Skip Specifications
The specifications of the block skip function for the FCP IV-3 are as
follows:
• Block Number Restrictions
Block numbers can be set from 0 to 255.
• Managing the Skip Sequence in the Program
When a skip sequence is set in the program using the MCS/2H Editor,
there is no distinction made between a block and device sequence.
Moreover, the skip sequence cannot be cancelled at the FCP IV-3.
• Marks Permissible On One Board
Including fiducial marks, a maximum of 255 marks are permissible.
• Block Skip Mark Restrictions
Size: Set in MCS/2H.
Mark color: The mark should contrast with the board color so that the
camera can read it easily.
Location: Same as fiducial marks.
• Conditions Under Which Block Skip Marks Are Read
When the letter "B" has been entered into the sequence data device
type (W) column, the machine looks for block skip marks.
• Conditions Under Which Block Skip Is Carried Out
An area of a certain size (Size_X, Size_Y) centered around the
coordinate location is inspected. If all this area matches the color
specified for the block skip mark, the corresponding block is skipped.
