SITRANS TH400 FOUNDATION field bus

Note
• The following points are necessary for the SITRANS TH400-FF to function properly:
– a unique node address;
– a physical device identifier for the fieldbus.
• The node address must be unique within the link (segment), while the physical device
identifier must be unique within the entire network.
● When delivered, the SITRANS TH400-FF has a unique physical device identifier.
● The device identifier is a concatenation of the string "SITRANS TH400" and part of the
serial number.
● The node address is set to "22".
● In the unit configuration, set the node address to a value that is unique within the link.
● To avoid address conflicts, the SITRANS TH400-FF automatically sets its address to one
of the temporary standard addresses between 248 and 251 as soon as it recognizes
another device with the same node address.
