Introduction

1. Introduction
Scalibur is a powerful modular controller for Niagara and Sedona. Scalibur stands
for scalability, a major characteristic of this controller. Scalability comprises several
aspects:
1) Scalable IO
A Scalibur station consists of the Scalibur controller and up to 63 terminals of the
modular Inline system. The terminals are available in a wide variety of types:
digital and analog inputs and outputs with different numbers of channels as well
as functional terminals for DALI light control, pulse metering, MBUS or serial
interfaces.
2) Scalable software
Scalibur has been developed primarily for the Niagara framework. Niagara
applications are built with the software tool Niagara Workbench. While Niagara
is very powerful, it is not very well suited for specific real-time applications. In
order to realize such applications with Scalibur too, the controller has the
Sedona framework in parallel to Niagara. Sedona applications run with fixed
cycle times in the millisecond range and are created with the
Niagara Workbench. Beside the separate exclusive use of either framework, the
parallel use of Niagara and Sedona is supported. The Niagara and Sedona
application can communicate to each other with a Sedona driver for Niagara.
3) Scalable licensing
The license model for Scalibur is very flexible: a license comprises a certain
number of data points which can be integrated with Scalibur. These license
packs are available as first-time license (250/500/1250/5000/10000 data points)
or as upgrade license (500/1250/2500 data points). Sedona, as open source
project, doesn’t have any license fees.
4) Scalable IP network
Scalibur contains two logically separated IP interfaces and an integrated
Ethernet switch with four external ports. The configurable assignment of the
Ethernet ports to the separate IP interfaces and the usage of the spanning-tree-
protocol allow flexible topologies like daisy-chain and redundant ring-structures
for both the backbone and the local control network.

2. Device and System Overview
2.1 Hardware
2.1.1 Functional Overview
Fig. 2.1.1.1: SCA-340-L basic circuit diagram
2.1.2 Processor Core
Processor: ARM®Cortex®A8 / 1 GHz
DDR3 SDRAM: 1 GB RAM (512 MiB for hardware version < 06 – see serial label)
eMMC Flash: 1,8 GB
NVRAM: 512 KiB / (buffered for a power failure of 5 days)
RTC: buffered for a power failure of 5 days
The internal Flash memory can be extended with a microSD card.
2.1.3 Ethernet
The integrated Ethernet switch has 4 external ports, which can be assigned
independently to one of the two separate IP interfaces. If at least two ports belong to
an IP interface, then redundant communication paths can be established, for
example by connecting several devices in a ring. The Ethernet switch supports the
Rapid Spanning Tree Protocol (RSTP), as well as a ring monitoring function to
automatically switch off redundant paths, and a broadcast storm protection function.
Factory default: eth0 is assigned to LAN3/LAN4, eth1 is assigned to LAN1/LAN2,
and RSTP and ring monitoring are deactivated.

Device and System Overview

2.1.4 Serial Ports
Both RS-485 ports have switches for bias and terminating resistors, and are
galvanically isolated from each other and the rest of the circuit.
Further serial interfaces may be added using modular IO terminals (M-Bus, RS-232,
RS-485, RS-422).
2.1.5 USB
USB 1 is a USB-OTG port with Mini-USB socket, and is used for installation and
maintenance. Connected to a PC, it allows to control the device via console and to
access the internal installation web site for device configuration and data point test.
The second USB port (USB 2) allows to connect USB end-devices.
2.1.6 LON
The SCA-340-L has a LON interface according to the CEA-709 standard, to connect
directly to LonMark TP/FT-10 networks.
2.1.7 Inline Local Bus Interface / Modular IO Terminals
The local bus interface allows to connect up to 63 modular IO terminals. This
interface comprises the communication channel to the IO terminals as well as the
power supply of these terminals and their connected sensors and actuators.
Scalibur is a controller for the Inline IO system and unlocks the rich pool of Inline IO
terminals for building automation.
Inline is a modular IO system by Phoenix Contact, to flexibly and quickly build up
space-saving automation stations. An Inline station consists of a bus controller and
a set of IO terminals, chosen freely in terms of numbers, type, and sequential
arrangement. The bus controller runs the Inline station and has interfaces to the
higher level controller. Up to 63 IO terminals can be connected to a bus controller.
There are IO terminals for almost any purpose:
digital inputs and outputs with 1, 2, 4, 8, 16, or 32 channels per terminal
Triac and relay outputs for switching signals or for higher loads
analog inputs for measuring voltage, current, resistance, or temperature
with 2, 4, or 8 channels per terminal
analog outputs for voltage or current with 2, 4, or 8 channels per terminal
function terminals for complex IO operations or gateway functions (DALI,
M-Bus, S0 pulse metering, serial interface)
supply and support terminals , e.g. to realize separated voltage domains
within an Inline station
The overall width of the Inline extension terminals is 1, 2 or 4 DU (1 DU, division
unit = 12.2 mm or approx. 0.48 in.).
Inline terminals are provided with a pluggable wiring level enabling pre-wiring and
easy module exchange.
The mechanics of the system also allows exchanging terminals without complete
dismantling of the station.
Scalibur determines type and function of all supported terminals automatically, thus
certain in- and output functions can also be created without a previous configuration
of the station, which is especially helpful for commissioning tests.

Device and System Overview
Manual SCA-340 / SCA-340-L sysmik.de 9
2.2 Software Overview
Scalibur is using a Linux operating system, which runs several applications in
parallel.
Fig. 2.1.7.1: Scalibur software structure
2.2.1 Scalibur System Shell
The Scalibur System Shell is accessible only via the local USB-OTG port, and is
used during commissioning to configure basic settings like IP address, or as
maintenance access if IP address or passwords have been lost.
2.2.2 IO Server
The IO server controls the modular Inline terminals of the Scalibur station and
manages concurrent accesses to the hardware data points. Niagara and the IO
server communicate via an TCP connection. This allows to control IOs remotely
from another Niagara station. The remote access can be limited or disabled by the
setting of the IP address of the controlling station.
2.2.3 Commissioning Web Server
The commissioning web server is exclusively accessible via the local USB-OTG
port. It presents web pages to commission the device: setting IP addresses and time
zone, reading state of inputs and setting output states of the data points of the local
IO terminals for test purposes.
2.2.4 Sedona Virtual Machine
The Sedona virtual machine (SVM) runs the Sedona application in real-time with
configurable cycle time. The Niagara Workbench connects to the SVM to modify the
application, load updates, or create backups of the application. Platform specific kits
provide access to the IO terminals, and also to system settings like IP addresses

Device and System Overview
10 sysmik.de Manual SCA-340 / SCA-340-L
and Modbus settings. A Modbus TCP server and a Modbus TCP client/Modbus RTU
master are integrated and are used to exchange data with other Sedona controllers.
Also, Niagara can be deactivated here.
2.2.5 Niagara Framework
Scalibur can be parameterized with Niagara Workbench and a platform connection
to the Niagara daemon. This includes loading of software updates and of a station
(Niagara application), which can be run automatically by the Niagara daemon.
A Workbench connection to a station is used to modify the station. All features of the
Niagara framework are available:
data point integration over a plethora of open automation protocols (LON,
BACnet, KNX, M-Bus, Modbus, and others) with data normalization
system functions (scheduler, alarming, trend log)
web visualization
enterprise interfaces (oBIX, data bases) and many more

3.1.2 Mounting
Preferred mounting position is horizontal (i.e. on a horizontal DIN rail which is
attached to a vertical wall). For all other mounting positions, a derating has to be
observed (see chapter 6).
Note: The air vents have to be kept free with a sufficient spacing to other components, to
ensure optimal air ventilation.
The device is designed for easy snap in mounting on 35 mm x 7.5 mm
DIN EN 60715 rails (formerly DIN EN 50022).
Note: The DIN rail should be attached to a mounting plate or an even back plane for best
stability.
Suitable fixtures, like end clamps or grounding terminals have to be used at both
ends of the station, to prevent sliding off the rail.
Note: To ensure easy unlocking of the Ethernet connectors, use only clamps at the bus
controller side of the station that do not protrude more than 30 mm from the rail.
Note: Only use clean and corrosion free mounting rails in order to ensure a safe contact
between the FE terminals.

3.1.3 Adding Inline Terminals
An Inline station is assembled by plugging the individual components to each other,
thus establishing the potential and bus signal connection between the individual
components of the station. Figure 3.1.3.1 shows the procedure of mounting a
terminal.
Disconnect power to the entire station.
Mount the electronics base onto the rail (A). Adjacent terminals are
interlocked by their feather keys / keyways (B).
First insert the feather keys of the local bus into the keyways of the
preceding terminal (B1).
Guide the feather keys along the keyways until they lock appropriately
(B2).
Ensure that the feather keys are properly connected (C2). C1 shows the
common mistake that the feather keys are not inside their keyways.
After mounting all electronics bases install the connectors onto their
respective bases. First insert the front detent (D1). Then push the
connector onto the electronics base until the rear detent locks properly
(D2).

3.2.2 Power Supply
3.2.2.1 How to Connect Power
The bus controller is operated with 24 V DC. The bus controller is powered from this
source and it generates the logic voltage for the logic circuit and the analog voltage
for the analog circuit. The logic circuit supplies the internal bus including the
communication chips of all connected automation I/O terminals. The analog circuit
provides an auxiliary supply for analog signals.
Note: While connecting the automation terminals please observe the derating of the logic
voltage, the supply of the analog terminals, and the maximum ampacity of the terminals.
Furthermore the bus controller includes connections for the supply of the mains and
segment voltage of the Inline station.
Fig 3.2.2.1 shows the basic circuit for the connections of the power supply.

Note: If UBK/UMand USare to be supplied from a common source, the fuse protection of the
individual sections with regard to their supply requirements has to be observed.
Note: The current passing through terminals and potential routing contacts must not exceed
8 A.

3.2.2.2 Power Dissipation Calculations for a Scalibur Controller
The power dissipation of the bus controller equals the sum of the power
requirements of the bus controller itself and the power loss of the internal power
supply for the whole Inline station:
PSCA=
PO+ PUSB+ PPERI
PSCA power dissipation of the bus controller
POpower requirements for operating the bus controller without
terminals and any external load (4.1 W)
PUSB power dissipation of the bus controller caused by the load on
USB1 and USB2 (max. 500 mA each)
PUSB = 0.7 V × ( IUSB1 + IUSB2)
PPERI power dissipation of the bus controller caused by the Inline IO
terminals
PPERI= 1.0 V × IL
ILcurrent consumption of UL
Note:The factors 1.1 V und 0.7 V result from the electrical efficiency of the internal power
supply unit.
Sample calculation: Power dissipation of a Scalibur in case of the maximum
possible current drawn from ULand a USB memory stick with 0.1 A current
consumption.
PSCA = 4.1 W + 0.7 V × 0.1 A + 1.0 V × 2.0 A
PSCA = 4.1 W + 0.07 W + 2.0 W
PSCA = 6.17 W

Installation and Commissioning
18 sysmik.de Manual SCA-340 / SCA-340-L
3.2.2.3 Current Consumption Calculation for a Scalibur Station (with Terminals)
To find a suitable external power supply, the current consumption of the entire
Scalibur station has to be considered:
IIS= ISCA + IUSB + IK+ IAS
IIS current consumption of the entire Scalibur Inline station
ISCA current consumption of the Scalibur
IUSB current consumption of connected USB devices
IKcurrent consumption of connected terminals
IAS current consumption of sensors and actuators, fed by the Inline station
The current consumption of a Scalibur (without terminals) is maximum 170 mA.
ISCA = 0.17 A
Please consult the manual of the connected USB device to find out the actual
current draw from USB.
The respective USB currents IUSB1 and IUSB2 are weighted by a factor of 0.24,
resulting in the equation:
IUSB = (IUSB1 + IUSB2) × 0.24
The current consumption of the connected terminals can be found in their manuals.
The following rules of thumb apply:
The current provided by UANA influences the total current directly.
The current provided by ULapplies to the total current with a factor of 0.36.
The following formula applies:
IK= IA+ IL× 0.36
IAcurrent from UANA (max. 500 mA)
ILcurrent from UL(max. 2.0 A)
See the according datasheets in order to determine the current consumption of the
connected actuators and sensors.
For an estimation it is often sufficient to check, whether the supply can be provided
completely by the Scalibur, that is without power or boost terminals.
Without power and boost terminals and regardless of the circuits UMund US, the
maximum current consumption of the Scalibur with connected terminals is 1.7 A.
In addition there are the current requirements of the sensors and actuators, whereas
the current through feather keys and keyways is limited to a maximum of 8 A.
Note: When selecting an external power supply, plan sufficient reserves. also into account
that it could come to a current increase to a multiple of the rated current in the moment of
turn-on caused by input capacities. Power supplies with over current shut-down must have a
sufficient response delay to avoid start-up problems.
3.2.2.4 Derating of Terminal and USB Supply
Because USB and the Inline terminals are supplied by Scalibur’s internal power
supply unit, an increased load there increases Scalibur’s internal power dissipation.,
Therefore, a derating has to be observed, which is depending on the mounting
position (see Fig. 3.2.2.4). The recommended mounting position (with least derating)
is horizontally (that is, clipped to a horizontal DIN rail on the wall).
The internal power dissipation caused by USB loads (PUSB) and the connected Inline
terminals (PPERI) is calculated according to chapter 0.

Installation and Commissioning
Manual SCA-340 / SCA-340-L sysmik.de 19
Fig. 3.2.2.3: Derating diagram of maximum internal power dissipation
Please refer to the manuals of the Inline terminals to find out the load of the logic
supply.
Maximum load on the logic supply (2 A) and on USB (2 x 500 mA) leads to a 100%
power dissipation of 2.7 W:
PV= 1.0 V × IL+ 0.7 V × IUSB
PV= 1.0 V × 2.0 A + 0.7 V × 1.0
A = 2.7 W
This power dissipation can be maintained up to a maximum environmental
temperature of 40 °C (104 °F). For higher temperatures, the load (PPERI and PUSB)
must be reduced according to Fig. 3.2.2.3.
Example 1: Horizontal mounting position
For an environmental temperature of 55 °C (131 °F) and horizontal mounting, the
power dissipation is limited to 87 %, which means 2.35 W. Supposed ILis fully
loaded with the max. allowed 2 A, then the USB ports can support a maximum of
0,5 A:
IUSB = 0.87 PV– 1 V

Polarity reversal: Parallel diodes. In case of wrong polarity a high current is flowing
which is blowing the external fuses.
Segment supply and main supply are related to the same ground potential.
Note: Each 24 V voltage supply must be fused externally. The power supply unit must be
capable of supplying a current four times the nominal value of the external fuse to reliably
blow the fuses in case of an error.
