Structure of Exchange Library

• Documents are stored in an electronic media.• The Exchange Library is divided into various

modules.– A-Module - Library Survey– B-Module - O&M manuals– C-Module - Exchange Manuals – D-Module - Functional Product Documents– E- Module- S/W docs. , F- Module- H/W docs.– I - Module- Exchange Data ( Data Transcript ).

Exchange Library - O&M Modules

• O&M modules - B-Modules

• B- Modules is divided into :-– B-01 General Exchange Operations– B-02 Operating Instruction ( OPI )– B-03 Maintenance Instruction ( OPI )– B-04 Test Instruction– B-11 Command Description– B-13 Printout Description

B-14 Adaptation Instruction

Exchange Library - O&M Modules

• Other Modules - A-Module & D-Module.

• E-media also contains A-Module, B-Module & D-Module.

Commands & Printouts

• To communicate to the system, we need to know how to input command and to read printout.

• Command Structure :

Command Code : Parameter Name = Parameter Value

Commands & Printouts ( Command Structure )

• Command Code :– XXYYZ

• XX- Function Group

• YY - Function

• Z - Action

• Parameter Names – Separated by commas “,” if more than one.– Arrangement is not important.

Commands & Printouts ( Command Structure )

• Commands can be written as :– Commands with no parameters .

< IOROP;

– Commands without a parameter value< IODAC : ATT;

– Commands with a single value.< EXRPP: RP=1;

– Commands with several numbers or range.< EXRPP: RP=1&3&5&&12;

Commands & Printouts ( Command Structure )

• Special Characters :– & - And– && - From - To– { }- MUST enter one option and one option

only– [ ] - Depending on command, could optional

• B-11 Module - Description of all commands including the parameters.

Command & Printouts ( Printouts )

• Several Types :-– Automatic Printout

• Printout by system because of errors in system.– Alarm

– Alarm List ALLIP , ALLTC

– System Restart

– Command intiated restart.• Check Printout

< SYREI :RANK=SMALL;

< SYREI: RANK =SMALL; <= Check Printout

< ; <= TO CONFIRM

Command & Printouts ( Printouts )

– Command intiated restart - cont.• Procedure Printout

– Receives immediately after command input.

– Eg.

» Executed

» Ordered ( F1 to release to get printout )

» Not Accepted

Command & Printouts ( Printouts )

– Command intiated restart - cont.• Answer Printout

– Printout receives as a output from the system immediately.

Command & Printouts ( Printouts )

– Command initiated restart - cont.• Procedure Printout

– Printout receives as output from the system but at a later time

– Always preceded by ORDERED procedure printout.
