2.1 Hardware Units

The TAC Xenta 280/300/400 family consists of the following units:
• The TAC Xenta 280/300/401 controller. The controller contains the database of the inputs and outputs of the TAC Xenta system. It also contains the system and application software for all the func­tions that are to be performed by the controller and the connected peripheral units.
• TAC Xenta OP. The operator panel includes control buttons while a screen displays the values and menus. TAC Xenta OP can be connected to any controller in the network.
I/O expansion modules. These can be used to extend the number of inputs and outputs on a TAC Xenta 300/401 controller.
The I/O modules are described in a separate manual, TAC Xenta 400 I/ O Modules.

TAC Xenta 401 none none up to 10 3.3
A number of controllers and I/O modules can form a local network and exchange data.
The TAC Xenta OP operator panel allows the user to:
• Obtain access to certain parameters
• Monitor the system status
• Adjust setpoints and time channels
• Display alarms (without communicating with a central system) Up to two OPs may be connected to each controller.

2.2 Configurations

The TAC Xenta controllers can be used in different configurations, for example:
• As stand-alone units (for a TAC Xenta 401 with at least one I/O module).
• With controllers and OPs in a network, with extra I/O modules as required (no I/O modules for the TAC Xenta 280).
• With controllers, OPs, I/O modules and other equipment in a full network with suitable adapters, possibly with connections to a TAC Vista Central System.

2.3 Communications

The TAC Xenta units communicate with each other in a network using a common bus, Echelon® L
10). Additional I/O units also connect to the network and may be added as required. An I/O unit can only be associated with one controller.
Explicit L operator panel and the controller.
The L defined on foreign equipment.
The Functional Block applications are modeled as true L troller Objects.
The Network Variable interface (including the Standard Network Vari­able Types, SNVTs) can be customized, and External Interface Files (XIFs) can be generated in the field using the TAC Menta tool. Avail­able SNVTs are listed in an appendix to the Engineering Applications in TAC Menta manual.
When connected to a TAC Vista Central System, the operating con­ditions of equipment such as fans, pumps, and recovery units can be dis­played as graphs on the monitor and printed as reports. All temperatures and alarms may be read, while setpoints and time settings may be altered as required
TAC Xenta controllers can be reached from TAC Vista in many ways. Using LonWorks in the Xenta controller, some examples are:
• From a PCLTA card in some form, directly on the PC.

• Via the LTA function in the TAC Xenta 911.
• Via the LTA function in the TAC Xenta 511.
• Using the TAC Xenta 901.
• Via an Ethernet/LON gateway.
Using the serial channel in the Xenta controller, for example:
• Directly connected to a PC serial channel.
• Connected to a PC serial channel via a telephone modem.
• Connected to a PC serial channel via the IP modem function of the TAC Xenta 911.
Starting from v 3.1, application programs generated in TAC Menta may be downloaded from TAC Vista via the network.
The TAC Xenta 280/300/401 can communicate as follows:
• It can send alarm and trend logging (versions 3.2 and higher) mes­sages.
• It can answer requests for the status of inputs and outputs.
• It can send/ any of the parameters/variables in the program which are freely available (“Public signal”).
• It can communicate with other T AC Xenta controllers to exchange data.
• It can communicate with the Operator Panel, the I/O-modules, and TAC Vis ta.
For further details, please consult the TAC Vista IV, Engineering Clas- sic/LNS Network manuals.
RS232
The TAC Xenta 280/300/401 controller has an RS232 port that can be used to:
• Load the system software.
• Load the application software from the TAC Menta programming tool.
• Connect to TAC Menta when used as a commissioning tool.
• Connect a specific controller directly to T AC V ista or via a modem (modem connection not available with TAC Xenta 280).
• Retrieve the “System Error Log File” using the “Xenta System Error Log Viewer”.

TAC Xenta 283
Fig. 3.2: The terminals of the TAC Xenta 281, 282, and 283
Inputs
All TAC Xenta 280 controllers have digital inputs (X).
The TAC Xenta 281 and 282 have universal (analog or digital, U)
inputs. The universal inputs can be used for three types of signals:
• TAC thermistor 1.8 kohm at 25 °C (the same as the thermistor inputs)
• Voltage input 0–10V
• open/closed contact (the same as the digital inputs).
The TAC Xenta 282 also has thermistor inputs (labeled B) for
1.8 kohm.
The TAC Xenta 283 has thermistor inputs (labelled B) that can be used with either 1.8 kohm or 10 kohm thermistors.
All controller inputs are protected from transients, in compliance with the EN 50082-1 norm.
Outputs
The TAC Xenta 281 and 282 have the following outputs;
• Analog (Y) — 0–10V DC outputs
• Digital (K) — relay potential-free outputs
While the TAC Xenta 283 has TRIAC (V) — outputs capable of sup­plying inductive loads.
3.1.2 Jacks
18 (74) Schneider Electric Buildings AB, June 2011
The TAC Xenta 280 has two modular jacks–one for the TAC Xenta OP operator panel and one for an RS232 connection with TAC Menta.
The socket for the operator panel provides it with 24V AC or DC, depending on the supply.

TAC Xenta, TAC Xenta 280/300/401 3 Technical Description
Service pin
Red service diode indicates a non-configured node or a hardware fault
Green status diode indicates that the program is running
At distances greater than 10 m (32 ft.) between the TAC Xenta control­ler and the OP, an external power supply should be used. In addition, the communications connection has to follow the same rules as for other nodes.
Jack for the RS232/modem
Fig. 3.3: Location of jacks on the TAC Xenta 280 controller
3.1.3 LED Indicators and Service pin
The Service pin can be activated through a small hole on the front. Also on the front, there are two LED indicators–one red and one green.
Jack for the Operator panel
Fig. 3.4: LED Indicators and Service Pin
The red service diode is primarily an error indication. It also lights up if the Service pin is activated.
The green status diode blinks once per second to indicate that the pro­gram is running.

Inputs
The TAC Xenta 300 controllers have twelve inputs:
• Four thermistor inputs (labeled B1–B4)
• Four universal (analog or digital, U1–U4)
• Four digital (X1–X4). The universal inputs can be used for three types of signals:
• TAC thermistor 1.8 kohm at 25 °C (the same as the thermistor inputs)
• Voltage input 0–10V
• Open/closed contact (the same as the digital inputs)
All controller inputs are protected from transients, in compliance with the EN 50082-1 norm.
Outputs

TAC Xenta, TAC Xenta 280/300/401 3 Technical Description
3.2.2 Jacks
The TAC Xenta 300 has two modular jacks–one for the TAC Xenta OP operator panel and one for an RS232 connection with TAC Menta.
The socket for the operator panel provides it with 24V AC or DC, depending on the supply.
At distances greater than 10 m (32 ft.) between the TAC Xenta control­ler and the OP, an external power supply should be used. In addition, the communications connection has to follow the same rules as for other nodes.

The Service pin can be activated through a small hole on the front. Also on the front are two LED indicators–one red and one green.
Red service diode indicates a non-configured node or a hardware fault

The red service diode is primarily an error indication. It also lights up if the Service pin is activated.
The green status diode blinks once per second to indicate that the pro­gram is running.
