Time-out Check Time

The time out check time refers to the duration after termination of receive (final character
received) of a failed transmission from the computer to the programmable controller, until the
send sequence is initialized.
This check time is specified as follows depending on the model and version of the programmable
controller.
To set the time-out check time as 60 ms:
M8002
FNC 12

It must be noted that the time-out check time is not updated until the next character is received,
and hence must be set to at least more than the time necessary to receive one character at the
baud rate (transmission speed) in use. When 1 character = 12 bits, the minimum setting of time-
out check time is as follows.
