Software Description

Varec, Inc.

4 Software Description

The Tank Gate Interface software platform is based on a real-time, multi-tasking operating

system. The software consists of I/O scanning functions for data acquisition, a database/

database manager and communication functions for data transfer.

Note COM1 is not available on the 8315 Tank Gate Interface.

Software Features

4.1.1

Real-Time / Multitasking Executive

The operation of the Tank Gate Interface is based on a highly reliable, field-proven real-time

multitasking executive. It provides task switching based on real-time events and interrupts,

message passing and task priorities. Its capabilities also include timed suspension of tasks,

queue handlers and interrupt processing tasks.

4.1.2

Real-Time Clock

Integral to the real-time executive is the system’s real-time clock. All timed events of the Tank

Gate Interface are coordinated by this clock. In addition to the real-time executive interaction,

all field data scanning is coordinated by the real-time clock.

4.1.3

Automatic Fault Recovery

The Tank Gate Interface has a watchdog timer that is periodically strobed by the microprocessor.

Should the processor suffer a lapse due to hardware or software failure, the watchdog timer will

time out and the Tank Gate Interface will then be reset and normal operation will resume.
