Postec Communications Controller (PCC)

Postec Communications Controller (PCC)

At the heart of today’s low margin, volume based, fueling environment is the Postec Communications Controller. The PCC operates a wide variety of devices and features comprehensive onboard reporting.

Built on solid state technology this high quality controller has been proven in the harshest of conditions and provides the opportunity to enhance or develop new products, without replacing the existing device.

  • Increased system uptime
  • Plan for future growth
  • Improve business efficiency
  • Improve customer experience
  • Reduce your costs
  • Protect your investment Proven solid state technology
  • Secure from PC hackers and viruses
  • Modular and scalable
  • Built for supportability
  • Head office ready

The PCC hardware is also modular in it's architecture. The base unit consists of a metal cabinet, mains power supply and a main CPU circuit board from which the software is run.

The main circuit board contains the following hardware:-

Master CPU 80c31 micro controller supporting serial port, timers, RAM etc…
64 K bytes of EPROM (Contains the PCC software)
128 K bytes of non volatile static CMOS RAM (for data storage)
256 bytes of EEPROM (for configuration data)
8 DIP switches for hardware configuration
Calendar clock with alarm
Eight channel UART (OCTART) for auxiliary serial communications
Intelligent Communications Bus for slave CPU and peripheral expansion (12C bus)

The cabinet design accommodates mounting of interface and expansion circuit boards to allow the hardware to support more complex systems.

Modular Serial Interface cards have been developed to provide connection to external devices.

e.g. RS-232 /RS-484 interface
e.g. Current loop interface

Intelligent cards have been developed to further expand the hardware.

e.g. Parallel Input / Output interface
Universal Pump Interface cards for connection to proprietary interface circuits.
V22 Intelligent modem interface
RAM Pack expansion card (non volatile memory for infrequently Accessed
data storage)

The modular architecture provides a system capable of expansion to cover future system application requirements without adding to the cost of the basic unit.
