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)
<For MCS>
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
<For F4G>
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.

(2) Setting Sequence Information Data
<for MCS>
In MCS systems, the sequence information is set at N_data. For part sequences which
use a next device, specify the original device number under the “D” heading.
<For F4G>
In F4G systems, the sequence information is set in the Sequence Data. For part sequences
which use a next device, specify the original device number under the “Slot#” heading.
(3) Device Table Change Trigger
In next device mode and device change mode, there are times when certain problems
occur (i.e. when there is a picking error, vision processing error or when a feeder has run
out of parts) and it would not be advisable to automatically change device tables. On the
other hand, there are also times when these problems occur but where the device table
could be changed. The choice is left to the operator to decide under what circumstances
the device or device table will be automatically changed.
Proper data setting:
[Proper]
78. D Change Trigger Error, Parts, Miss, PD
Error The device or device table will change when the device is out of parts, not
picking properly or experiencing a vision processing error.
Parts The device or device table will change only when the current device is out of
parts.
Miss: The device or device table will change only when the device is out of parts or
not picking properly.
PD: The device or device table will change as specified in Part Data (explanation
follows).
When this Proper data item is set to “PD”, the device table trigger will change to the
condition that has been set in the Part Data of each respective part.
