ASCII Interface Module (AS311)
5. Operation Procedure
5.7 Setting the time-out check time
The default setting of the time-out check time is 1 second. The time-out check time
can be changed by T3 program. The valid setting range is 0.1 to 60.0 seconds in 0.1
second units. Refer to section 4.2.3.
To change the time-out check time, write desired value into the AS311’s buffer memory
address 25 (CH1 time-out check) and/or address 89 (CH2 time-out check), and
execute the hot reset (refer to section 5.5).
T3 program for this purpose is almost same as that for setting the trailing code (refer to
section 5.6). Only the difference is writing the time-out check time instead of the trailing
code. See Rung 2 of the following sample. In this sample, the channel 1 time-out check
time is changed to 5 seconds.
If the channel 2 time-out check time and/or the trailing code are also changed, write
these data on the Main program Rung 2 before calling Subroutine No. 3 in the same
manner.
