Since 1978, Smar has been a powerful contributor in setting the pace for the evolution of technology in the automation field. New products and new ideas to bring solutions closer to the user's dream.
The first 16 bit digital controller, the first transmitter with embedded PID control, the first commercial line of Fieldbus products for process automation, are examples of the pioneering achievements of Smar.
The LC700 now joins the family of Smar products setting up the bridge between process and manufacturing automation and Fieldbus.

Interfaces
PCI
Process Control Interface
The PCI card can be plugged directly into the internal 16-bit ISA bus of an industrial or conventional PC, enabling supervisory software to easily access all FIELDBUS data acquired by the four channels. POWERFUL ARCHITECTURE The board has the size of 3/4 PC AT card and it allows for hot insertion or extraction when installed in an industrial computer. Four SMAR modems, a 32 MIPS superscalar RISC CPU with dual port memory and a 32-bit architecture guarantee outstanding performance and data integrity. ADVANCED PROCESS CONTROL CAPABILITY High processing power and access to multiple FIELDBUS channels make PCI ideal to handle complex control and mathematical functions. FIELDBUS MASTER DEVICE The PCI can work as a bus master for all four FIELDBUS channels. DATA ACQUISITION A simple DLL (Dynamically Linked Library) called PHAL (PCI/BC1 Hardware Abstraction Layer) interfacesWINDOWS™ applications such as supervisory systems, configurators, etc to the PCI hardware and software. This DLL guarantees complete FIELDBUS hardware and software transparency. FLEXIBLE PROGRAMMING The PCI executable program remains in RAM. It has object oriented programming and the configuration and exec programs can be downloaded very easily. With its open protocol, it can be used with virtually any WINDOWS™ or DOS™ applications. It is the ideal tool for plant operation and supervisory software. |
Accessories
SB302
Isolated Safety Barriers
 |
The SB302 safety barrier provides intrinsically safe power for field instruments. Since it works as a repeater, the FIELDBUS signal can be freely used on the safe side of the barrier. Galvanic isolation of the signal relaxes grounding requirements and all the other special care required when a good barrier ground is necessary. The barrier contains bus terminators and complies with the most rigorous Intrinsic Safety standards. |
PSI302 Fieldbus Power Supply Impedance
The Fieldbus Power Supply Impedance is a non-isolated, active impedance control device, fundamental for the implementation of a Fieldbus network in accordance with Standard IEC 1158-2. This device presents an output impedance which, in parallel with the two bus terminators, (a 100 ohm resistor in series with a 1 uF capacitor) required by the standard, results in a purely resistive line impedance for a broad frequency range. The purely resistive line impedance prevents unwanted oscillation and distortion of the communication signal caused by signal variation (ringing effect).
The PSI302, because of the power
supplied, cannot be used directly in areas requiring intrinsic safety specifications.
In this case, it becomes necessary to use an intrinsic safety barrier to
separate the safe area and the dangerous area.
Back to Top
The PS302 is a switched power supply unit (non-intrinsically safe) with universal input (90 to 260 Vac, 47 to 440 Hz or a DC equivalent) and a fixed output voltage (24 Vdc) which, coupled to a PSI (power supply impedance) is apropriate to feed Fieldbus elements. Isolated, with short-circuit and overcurrent protection, ripple and fault indication, it is apropriate to feed Fieldbus elements.

The SYSCON is a powerful and user friendly software tool to configure, maintain and operate a FIELDBUS based system through a PC. The WINDOWS™ graphic user interface is so easy to use that no previousknowledge of computers is required. The computer can communicate with a FIELDBUS network via a BC1, a PCI or any other suitable interface. The software includes the functions:
SYSTEM AND DEVICE CONFIGURATION
With this function it is possible to communicate with all devices in the network, assign tags, configure the control strategy, adjust parameters and download a configuration.
SYSTEM MAINTENANCE
This function communicates with all field instruments, and accesses information about instrument manufacturer, materials of construction, ranges, etc. It also allows for transducer calibration and controller tuning. The on-line diagnostic report is a very powerful tool for plant reliability. Complete maintenance reports are issued according to the user's configuration. Alarm and events reports are issued on line.
SYSTEM OPERATION
The user can have indication of variables, historical trends, alarm logs, etc. They can also change parameters and settings or send commands. It is the ideal tool for plant commissioning!
