5. Next Device
On the FCP IV-3 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”.
Next device is set in the production program using the MCS/2H Editor. A
simple example with explanation follows.
5.1 Setting Next Device
5.1.1 Setting Device Information Data (D_data)
Under the “Next” heading in device information data is the device
number of the device to be used after the previous device runs out
of parts. 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.

5.1.3 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:
78. D Change Trigger
• 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).

• 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.
5.2 Next Device Operation
Herein is an explanation of how the Next Device function operates.
(1) In the production program, a device number (D) from which parts are
to be picked is set in Sequence data. This is the original device.
(2) When the original device is out of parts, it will change to the device
number set in “Next” of Device data (D_data).
(3) After that, when parts run out again, if the number in “Next” is not
the original device, it will go to that device.
(4) If the number specified in "Next" is not the original device and there
are no parts on this feeder, and if the final next device is out of parts,
automatic operation will be interrupted.
Note: For further information on the Next Device function refer to the
MCS/2H Operation Manual.
5.3 Points to Remember When Using Next Device
In the production information the next device is not considered. Parts
picked from all original devices are totalled.
When setting next devices a loop must be set. This loop can use up to 30
devices.
When next devices have been set, the time required per cycle increases.
