1. MODS Instrument Software

2. MODS Instrument Software  Interjoined Software Logic (ISL) System  Parts of the ISL system  Tasks involved in MODS operations.

3. MODS Instrument Software (ISL) control system for:  monitoring  controlling  data acquisition

4. MODS Instrument Software (ISL) Although a project seems to be very small, and does not require to many resourses in the beginning.

5. The true nature of a project is not always immediately obvious!

6. MODS Instrument Software

7.  Accepts commands interactively from a user.  Execute a predetermined lists of commands.  Schedule tasks when timing is important. MODS Instrument Software (ISL)

8.  semaphores utilities.  Inter-task communications utilities.  Allocates and provides shared memory utilities. MODS Instrument Software (ISL cont.)

9. MODS Instrument Software ‘isl’ ( task interjoins other tasks and/or systems together ) ‘isl’ ( task interjoins other tasks and/or systems together )  Initialize all tasks and shared memory.  Interjoins multiple tasks on to itself.  Starts On-line tasks.  On-line task: task that is started and terminated by ‘isl’.  Off-line task: task that is started from the prompt. It is not terminated by ‘isl’ but can enjoys the use of all the ‘isl’ utilities

10. MODS Instrument Software ‘initall’ – Off-line Initialize Shared Memory  Only task that is not started in background reason is obvious

11. MODS Instrument Software ‘islmgr’ – On-line ‘islmgr’ – On-line  Started by ‘isl’ as an On-line task.  Manages input/output.  Searches for appropriate tasks, and passes information.

12. MODS Instrument Software ‘ islerr ’ – On-line  Looks up error number.  Assigns a human readable message.  Send message to a logging task.

13. MODS Instrument Software ‘ msgout ’ – On-line  Generates a new filename, using date.  Logs all errors and messages generated by all interjoined tasks.

14. MODS Instrument Software ‘quickC’ – On-line  Quick commands for mechanism control  Quick commands for procedures, list, PLC program loading.

15. MODS Instrument Software SNTools – Off-line Standard Notation Tools  Standalone tasks for monitor and control.  Written as needed.

16. ‘Comtrol’ and ‘WAGO’ Hardware will use on-line and off-line tasks  Tasks such as quickC, comtrol, fieldtalk, etc. will talk to these communication devices for mechanism control for on-line tasks as well as off-line tasks if needed. Some tasks checkr, monit, etc. will be used for wellness monitoring on MODS. MODS Instrument Software

22.  DCS based on MS DOS for testing with Data handling integrated  A Linux DCS may be integrated into ISL before MODS is delivered.

23.  Data handling integrated  Satisfy data, speed, access requirements as become know. MODS Instrument Software

24. conclusion  We will have a modular system  System can be modified easily.  Adding tasks and attaching them to shared memory will be simple.
