Honeywell FC-USI-0002 Universal Safety Interface CC

Honeywell FC-USI-0002 Universal Safety Interface CC

Description

The USI-0002 communication module handles Ethernet and Serial communication with external devices, e.g. Experion™ PKS and Safety Builder. It is located in the Controller chassis.

The main function of communication modules is handling the communication to and from external devices and other Safety Managers.

The USI-0002 communication module acts as hardware firewall, protecting the safety functions within Safety Manager. It has:

  enhanced protective capability.

  high internal memory for running multiple demanding communication protocols in parallel.

The module consists of the following items:

• A Motorola 8270 communication processor.
• EEPROM to store specific module data, such as the two MAC-addresses and the hardware revision number.
• 8 Mbyte Flash memory to store the system and application program. The flash content is copied to SRAM at startup and is executed from there. The flash content can be updated without removing the USI-0002 from the Controller chassis.
• 8 Mbyte Local SRAM (with Error Detecting and Correcting logic) for system and application program and information.
• 256 kilobyte shared RAM for data exchange between the USI-0002 and the Control Processor.
• Two dual-speed fast ethernet transceivers.
• Two general purpose serial communication controller channels.
