TIME OUT
A Time-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:
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) :
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.
