Setting the Operating Mode after a Communications Error

Connection error mode
Automatic Recovery
Stop Error Connections
Stop All Connections
The Extend Mode settings can be set when using the NE1A-SCPU01-V1 or
NE1A-SCPU02 Controllers (including NE1A-SCPU01-EIP and NE1A-
SCPU02-EIP). The Extend Mode Tab Page includes the Connection Error
Mode and Program Execution Delay. The Program Execution Delay can be
set only when using version 2.0 or higher (including NE1A-SCPU01-EIP and
NE1A-SCPU02-EIP).
An operating mode can be selected on the Extend Mode Tab Page of the Edit
Device Parameters Dialog Box to specify the Controller's operation when
there is a connection timeout during safety I/O communications with a safety
slave.
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 communications will restart automatically.
Specify this mode to keep safety I/O communications with a safety slave stopped after a safety
I/O communications error has occurred with the slave. To restart safety I/O communications
with the safety slave after I/O communications have been stopped, use the Network Configura-
tor to send a command to restart communications. It is also possible to write a logic routine in
the logic program in advance to turn ON the Safety I/O Communications Restart Flag and
restart communications with a specified trigger.
Specify this mode to stop safety I/O communications with all safety slaves stopped after a
safety I/O communications error has occurred. To restart safety I/O communications with the
safety slaves after I/O communications have been stopped, use the Network Configurator to
send a command to restart communications. It is also possible to write a logic routine in the
logic program in advance to turn ON the Safety I/O Communications Restart Flag and restart
communications with a specified trigger.
This function is enabled when safety I/O communications are normally established with all
Safety Slaves.
