13.1 TIME OUT

13. OTHER OPERATIONS RELATING TO IN-LINE SERVICE

The followings are other operations relating to in-line service operations.

13.1TIME OUT

ATime-Out condition arises when the Master Terminal is making an in-line service operation, such as X/Z report collection, DLL, etc. to the Satellite Terminals. The service timer is provided for servicing each of the Satellite Terminals, thus on exceeding the time limit, a Time-Out condition will occur. In this case, a “RETRY”, “SUSPENDING”, “INCOMPLETE ENDING”, or “CANCEL” operation will be accepted.

ex. 1) In a system with a Master Terminal and 3 Satellite Terminals:

MASTER

TERMINAL

busy S1 busy S2 S3

When a report collection is executed on the Master Terminal, a series of data collections from each terminal (S1 to S3) will be performed, but services for S1 and S2 will be skipped due to their “busy” conditions. Thereafter, services will again be attempted to S1 and S2. As a limit of 30 seconds is provided for servicing each terminal, the total service time in this case will be 30 sec. x 2 units = 60 sec. If data collection is successfully done from S1 within this time limit, servicing S2 follows for the rest of the time, and on reaching the time limit, the Time-Out condition arises, displaying on the Master Terminal the number of not-yet collected terminal(s) and the Store/ Register No. of the last serviced terminal. On this stage, the operator may only go on to “SUSPENDING” (to wait for a while until S2 clears the “busy” condition), or to “RETRY” (to execute collection service to S2 again, expecting that S2 has already cleared the “busy” condition), or to “INCOMPLETE ENDING” (to abandon the service to S2 and end with collection of the data of so-far collected terminals only), or to “CANCEL” operation. If “RETRY” is operated, the service time now is 30 seconds because only one terminal remains uncollected.

ex. 2)

MASTER

TERMINAL

busy	S1	No response	S2	S3
		(Power OFF)

In this case, S2 is in a “No response” condition and S1 is in a “busy” condition. As only one terminal is responding with some kind of status, a time out limit of 30 seconds is given (the “No response” status is not subject to the service timer). However, if S2 turns into a “Power ON” condition, it will also be subject to the service timer.
