Device and System Overview
8 sysmik.de Manual SCA-340 / SCA-340-L
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.
