The MultiFlow is informed whether the it is the first or last on the CAN bus
(termination has to be activated!) or not.

Dual Measuring System
With the use of dual or multiple measuring systems several MultiFlows
can share one printer. It must be ensured internally that only one
MultiFlow has access to the printer at any one time.
To fulfill this requirement, one of the MultiFlows must grant printing rights
to the other devices. This “Master MultiFlow” is always attributed the
node number “1” (parameter 3.1.6.1). All other MultiFlows should be
numbered in increasing sequence.
If the node number “0” is used, no CAN functions are activated.
Communication with the device is not possible.
9.3.1.14.1.2
OBC operation
With the use of an OBC interface the CAN Bus is used for communication
between the MultiFlow and the selected device. To activate the CAN Bus
a value greater than “0” must be entered in parameter 3.1.6.1 (global
node number). Normally the measurement units receive node numbers in
an increasing sequence, beginning with “1”.
To differentiate between the various ways of working the desired
operating mode is selected in parameter 3.1.4.1:
0: MultiFlow without OBC or TMC
(also multiple measurement system)
1: TMC operation
2: OBC operation
When using an OBC, the MultiFlow with the node number “1”
automatically transfers the printer administration to the OBC interface.
The OBC interface works in accordance with the EMIS specification
(European Multiple Interface System) from Sening, and is therefore
designated as an EMIS interface. Documentation is available on
request.
In the OBC operating mode a particular format is used for the form: a
discharge that has been carried out is recorded in a single original
documentation line.
