1.19.4 Points to Remember When Using Block Skip

It is possible for a block skip mark sequence to reference a fiducial mark, but the fiducial

mark sequence must be placed before the block skip mark sequence.

A block skip that is set using the machine command keys is valid until cleared by the

operator if the program being run does not have block skip mark sequences. For

programs which do have block skip mark sequences, the block skip flags set at the

machine are cleared before each new board is produced.

If a board which uses block skip marks, is cleared off in the middle of production and a

new board is then added by hand, production on the new board will continue using the

original block skip information of the previous board. On the other hand, if a new board

is loaded into the machine using the [LOADER] or [AUTO] function then block skip

marks will be read again and the block skip function will be carried out using this new

information.

1.20 Next Device

An empty device can be readied with the same part being used by another device so that

when the first runs out of parts, the next device can be used. This process is called “Next

Device”.

The next device setting is specified in the program.

Next device is set in the production program using the host computer’s editor. A simple

example with explanation follows.

1.20.1 Setting Next Device

(1) Setting Device Information Data (D_data)

In MCS systems, device information is set at D_Data. The “Next” setting specifies the

device number from which parts are to picked up when the current device is out of parts.

(At the final device, the “Next” setting should specify the original device.)

When this data is set the same type of part must be mounted in an empty device position

so that when the current device runs out of parts, the same part can automatically be

placed from the next device.

Part 2 Chapter 1 Basic Operation

Edition 1.1 2-1-85 CP643E System Reference

In F4G systems, device information is set at “Unit Data”. Enter the desired device

sequence in the “Next Part” column.

1. Start the GUE (Graphical Editor).

2. Open the Unit Data in the relevant program.

3. Select and copy the device line which specifies a “next device” setting.

4. Select a line which has no device setting, then paste in the data copied at step 3 above.

The same device setting may be specified at more than one line.

5. In the “Next Part” column, enter the sequence (at each line) in which devices are to be

used.
