6. Inter-board communication
This part provides communications between the ZXMSG 5200 and
peripheral resource boards, and communications between peripheral
resource boards. The processes between boards in the system can
implement direct logical addressing and communication.
7. R system monitoring
This part provides watch functions as CPU occupancy ratio, memory
use ratio, monitoring process endless loop, monitoring resource lost
and memory probe.
8. Environment monitoring
This part provides required communications and interface functions.
9. Network monitoring
This part provides
communications, including maintaining physical communication paths
between boards and Ethernet switching board, and monitoring
communications between Ethernet and boards.
10. Active/standby control
This part consists of operating and maintaining active/standby
hardware, controlling active/standby changeovers of other processes in
the system and maintaining ICS working address.
11. Alarm system
The system being an alarm interface module implements operations as
receiving foreground system alarms, collecting alarms, sending alarms
to the background,
background queries.
12. Startup control
This part implements
consequence, distributing startup information (events like power-on
and being changed over to the active part) during the system startup,
collecting process parameters in each startup phase and controlling
startup conditions.
13. File management
This module encapsulates the file system in the real-time operating
system and separates execution of real-time file operations from
process running; the module provides a unified file operation interface
for processes and an interface for inter-module file operations.
14. Diagnostic test
This test module provides functions as fault test and fault location
during the ZXMSG 5200 system running. The diagnostic test function
can be executed once per time according to background requirements.
15. Version management
This module maintains all system versions (including peripheral
boards'), including version uploading.
