8300 8315 L&J Tankway Software Description
4 8315 L&J Tankway Software Description
The TankGate 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.

4.1 Software Features
4.1.1 Real-Time / Multitasking Executive
The operation of the TankGate 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
TankGate 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 TankGate 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 TankGate will then be reset and normal operation will resume.
