With Ver. 1.0 and later Controllers (including NE1A-SCPU01-EIP and NE1A-
SCPU02-EIP), the user can specify whether to stop or continue I/O communi-
cations after the connection times out during safety I/O communications with
the safety slave. If I/O communications are stopped because of a timeout
error, the communications can be restarted from the logic program or a Pro-
gramming Device.
One of the following modes can be selected on the Extend Mode Tab Page to
specify the Controller's operation when there is a connection timeout during
safety I/O communications with the safety slave.
(For other settings refer to 5-7 Extend Mode Settings.)
Specify this mode to re-establish the safety I/O connection with a safety slave
after a safety I/O communications error has occurred with the slave.
If the cause of the communications error is eliminated, safety I/O communica-
tions will restart automatically.
