3. Brief Introduction
The AutroSafe Maritime Gas Detection System described in key
words is as follows:
All detectors are interactive addressable devices with intelligent
communication. Non-addressable detectors can be connected via
a 4-20mA interface.
Field devices have a built-in calibrated self-test to verify and
confirm their ability to perform correctly. This can be considered as
supplemental to – and can be used instead of – manual testing and
inspection routines.
Gas Detectors can be connected to the AutroSafe Panel by using a
2-wire loop structure (PowerLoop). The PowerLoop provides both
power to, as well as interactive communication with the detectors.
Studies have shown that a Gas Detection Control System’s cable
requirement can be reduced with 30-60% by utilizing this concept
as opposed to conventional systems.
The system is a modular and distributed system providing
maximum flexibility. The AutroNet communication facilitates the
possibility to link cause and effect across panels within the same
AutroNet. In other words, any gas detector connected to any panel
can activate any output associated to any panel. Each panel can
have up to 12 custom AutroSafe I/O modules. Within the limitations
of the system, the system designer can freely select the type and
number of modules to be used.
There are a number of versatile communication options available:
Physical: Ethernet, RS-232, RS-422, RS-485, Al_Com loop,
AutroFieldBus, PowerLoop and either hardwired or fibre-optic
based AutroNet (Ethernet).
Protocols: Modbus RTU Slave or Master, Modbus TCP/IP
Slave or Master, ESPA 4.4.4. and AutroCom (Autronica’s
proprietary protocol).
