Scadatron ST6000 Front End Processor

A Typical Telemetry Front End Processor

Front End Processors (FEP) are intermediaries of a SCADA communications hierarchy to offload data acquisition activities from the Master and to improve channel throughput.

The ST6000 Front End Processor (FEP) sometime referred to as Master Terminal Unit (MTU) provides a communication interface between Remote Stations with the
Master Control Center SCADA Man Machine Interface (MMI) computers. This Front End Processor (FEP) is capable of acting as a data concentrator to acquire data
from difference type of Remote Stations with a combination of different communication media such as PSTN, GSM, PSTN MODEM, VHF/UHF Radio or Satellite Communication without adding any extra processing load on the Man Machine Interface (MMI). Even the remote stations can be built using similar ST6000 embedded CPU and the differences is only on the I/O configuration and software loaded to the CPU.

The ST6000 embedded Front End Processor (FEP) is one of the industry most reliable controller which operate 365 days, 24 hours a day on critical SCADA operation without failure.

The ST6000 FEP is designed for easy support and maintenance due to it’s components used is based on industrial most common microprocessor, the Motorola 68000 and other ICs general available in the market today off the shelve. ST6000 provide simple solutions to Hot Backup Redundancy (HBR) feature by using two CPU, one as main CPU and another as standby CPU with data exchange between 2 CPU through the RS485 serial port.

The software for ST6000 CPU written in ANS-C language running in a real-time multi-tasking kernel designed for parallel processing / computation. Modification on application program is made easy by simply modify the targeted routine / software module without effecting other software routine. Data Logging facilities or historical data storage can be implemented in ST6000 FEP due to it’s large non-volatile memory (128Kx2) which is able to store at least one month of
