Embedded Solutions

Industrial automation is the use of control systems, such as computers or robots, and information technologies for handling different processes and machinery in an industry to replace a human being. It is the second step beyond mechanization in the scope of industrialization.

• Protocols: MODBUS, ASTM, HL-7, IEEE MIB, etc
• Industrial Networks and Communications: Ethernet TCP/IP, RS232, RS485
• Devices: RFID Devices, GSM/GPRS Module, LED Display, Mass Flow Meter, CNG Dispensers, CNG Compressors, Laboratory Analyzers

LAB Analyzer Interfaces

An instrument interface is an automatic, electronic connection between analyzer and computer for the rapid, accurate exchange of information.

Unidirectional: The traditional type of instrument interface is a unidirectional application: the instrument performs its test and transmits results to the interface device/host system in one direction only (upload).

Bi-directional: A bi-directional interface involves true two-way communication between the analyzer and interface/host. The host downloads specimen ID and test order information; the analyzer uploads specimen ID and test result information. Support of bi-directional interface capability is most generally found on random access testing instruments, which can perform a different array of tests on each successive specimen. Bi-directional interfaces where analyzer reads the tube barcode inquire LIS for the test orders and receive them, analyses the sample and report back the results to the LIS.

Most of the interfaces are based on ASTM standards of E-1381, low level protocol and E-1394, a high level protocol. True random access analyzers like general chemistry (Olympus, LX-20 and similar) and special chemistry (Axsym, Immulute and similar)

Interface Communication Standards:

• Standards structure
• The ASTM standard
• Common Data Format
• The HL-7 Standard
• The IEEE MIB effort
