8 Initialisation
At the power up, the 2600T FF executes some internal self-tests. Both the Hardware and the
memory contents are checked before to start the normal operations.
By default, the Function Blocks of the 2600T FF are not running, until a FB application is not
downloaded into the transmitter.
After the Function Block has been successfully downloaded into the transmitter, the FB´s start
to be scheduled producing an output value to be used for the Process Control.
By default the 2600T starts according to the following table

Important
Two output values (e.g. PRIMARY_VALUE and SECONDARY_VALUE) must always have
different channel numbers.
The Temperature Transducer Block only exists in 2600T – 267J / C, 269J / C transmitters and
the Multivariable Function Block only exists in 267C, 269C transmitters. The outputs for mass
and volume flow are dedicated to the Multi Variable Function. These outputs can also be given
to an Analog Input with choosing the channel 1001 or 1002.
