Set the Group ID

The Group ID refers to the logical QCPort group to which the QSNAP belongs. For further
information on the explanation of Group ID and the system configuration, see the IT. QCPort
System Install and Planning Guide (Publication No. MN05001002E).
The Group ID and SW1 A and B DIP switches are located at the upper right of the QSNAP, as
illustrated in Figure 5: Group ID Setting. CH Studio can view the settings for the Group ID, but
cannot be used to modify them.
Move the DIP switches to ON/OFF positions to create the Group ID. Moving a DIP switch to
the right is ON and moving the switch to the left is OFF. The Group ID is in binary with the
major units numbered to the right of the switch on the side label. Adding up the major units
set to ON determines the Group ID of the QSNAP.
Example: To set the Group ID to 25, start from the top (or 32) and set the switches to OFF, ON,
ON, OFF, OFF, ON (16+8+1=25).
Figure 5: Group ID Setting
When a gateway is present and presenting the QSNAP as remote IO, each device on the
QCPort must have a unique Group ID. If any two like QCPort devices have the same Group ID,
those devices will go off-line. Refer to the appropriate gateway install manual for information
on the data packet construction for that fieldbus (IT. DeviceNet Adapter Installation and User
Manual, Publication No. MN05004002E).
Once the Group ID is set, a power cycle is not required; after five seconds of inactivity of the
switches, the change takes effect. The Status LED indicates if the QSNAP is properly
configured; the LED is located on the lower right of the QSNAP, as illustrated in Figure 6:
QSNAP with 54 mm IT. Starter. For more information on the LED, see “Operation.”
