Guidelines for changing the device address
Note
The physical address of a FOUNDATION fieldbus device is read-only when the device is
commissioned or a host/linking device is detected on the fieldbus segment. To change the device
address, use the host system or remove the device from the fieldbus segment and connect it directly
to the Trex unit.
The host control system can assign an address to a device that is connected to a fieldbus
segment. When you assign device addresses, follow the guidelines below:
•
Addresses below 16 are not available.
•
Addresses between 16 and 19 are usually reserved for host systems. A device should
not be assigned in this address range.
•
Valid device addresses are between 20 and 247.
•
Addresses between 248 and 251 are temporary addresses. Devices without a tag or
address appear on the fieldbus segment at these addresses.
•
Addresses between 252 and 255 are reserved for visitors, such as the Trex unit.
