Nice Oview-TT Instrucciones Y Advertencias Para El Uso página 6

• Code lock/unlock – (function only available on NEO series motors).
Enables the user to lock/unlock the motor memory to prevent inadvertent
memorisation of additional transmitters.
• Data deletion – Enables access to the functions for deleting the motor
memory. The limit positions, operating parameters and transmitters can be
deleted as required.
4.2.2 - Description of items in the section "Common functions"
• Name – Enables the user to assign an identification "label" to the motor.
– Group: function accessible for skilled users of Oview-TT in a "TTBus" net-
work (read paragraph B in the second part of the manual).
• Firmware version – Enables the user to check which version of firmware is
present on the motor connected to Oview-TT.
• Hardware version – Enables the user to check which version of hardware
is present on the motor connected to Oview-TT.

A - Introduction: what is a bus network?
In the world of automation, the term bus network (local communication net-
work via cable between multiple automations) is used when there is the need
for correlated and centralised management of: a) control and operation of
two or more automations; b) operations for programming, diagnostics and
maintenance of devices making up these automations.
In general, a bus network comprises the following elements:
– the presence in the network of two or more devices;
– a "physical" connection between these devices by means of a single cable
(this may carry power supply or not);
– a "logical" connection between these devices based on the assignment of an
"address" (individual number) to each device and the subsequent recognition of
the latter by the system, during the data communication phase (this number
enables the system to route information exclusively to the destination device);
– the adoption of a "single language", shared and understood by all devices on
the network, which is expressed by means of a pre-set protocol (for example
the Nice standards "TTBus", "BusT4" etc. ) to encode data, transmit them and
decode them.

B - Using Oview-TT on a "TTBus" network
In general, all Nice devices equipped with the communication protocol "TTBus"
and physical connections dedicated to this technology can be connected to
one another to form a communication network. The physical connection is
made using a bus cable comprising two internal wires (power supply is on a
separate cable).
To construct a "TTBus" network made up of several motors, before physically
connecting the various devices to one another, the Oview-TT must be connect-
ed to each motor by means of the cable supplied, and each of these must be
programmed with a number called "group" (section "Menu" > "Common func-
tions" > "Group"), selecting a value between 0 and 63 for each motor (factory
setting = 0). As this number will be used by the "TTBus" system to specifically
identify each motor on the network, each motor must be assigned with a differ-
ent number that has not been assigned to another motor. This diversity
between numbers enables subsequent system identification and compilation of
a list of all motors on the network and thus routing of the relevant data to each.
Note – When a system comprises only one motor equipped with "TTBus" tech-
nology, this does not constitute a bus network (in order to be a network, it must
communicate with other motors); therefore this motor does not need to be
assigned a "group" number"
If Oview-TT is connected to this motor the system becomes a normal bus net-
work as the programmer communicates via "TTBus" technology. Also in this
case, the motor does not need to be assigned a ""group" number, because
Oview-TT has an individual group number that does not conflict with that of the
motor.
After assigning the "group" numbers to the various motors, connect the latter
to one another, using the "TTBus" cable. Then power up all motors.
Warning – For further information on connections and set-up of a
"TTBus" network, refer to the instruction manual of the motors or control
units equipped with this technology.
To program all motors on a "TTBus" network, connect Oview-TT to any motor
on the network; then switch on Oview-TT and wait for it to search for all motors
connected on the network (the group number of each is briefly displayed at the
top right of the screen. Note – This operation may last some time, depending
on the complexity of the network). In the meantime, Oview-TT displays the
"status screen" of the first motor found during the search procedure (the
motor with the lowest group number).
To program this motor, press the key (l) Menu twice and proceed with pro-
gramming as described in the first part of this manual. Otherwise, to select
another motor from those found by Oview-TT, press the key u (or t) several
