Resetting a Connection Stopped due to a Communications Error
When I/O communications have stopped in a connection due to a connection
timeout, I/O communications can be restarted in the stopped connection by
turning ON the Communications Reset Flag from the logic program or send-
ing a Communications Restart command from the Network Configurator. If the
Controller communications mode is set to stop all connections after a commu-
nications error, communications cannot be restarted in a specified stopped
connection. In this case, restart communications in all connections.
1. Restarting I/O Communications from the Network Configurator
After connecting online with the Network Configurator, select the Safety
Master, right-click to display the popup menu, and select Monitor to dis-
play the Device Monitor Window. The following window will appear when
the safety connection is selected.
Communications can be restarted in a connection where an error occurred
(evident from the connection status) by selecting that connection and clicking
the Resume Button. If the Resume All Button is clicked, I/O communications
will restart in all Slaves with which communications were stopped.
2. Restarting I/O Communications from the Logic Program
When the safety connection is set, the following logic program output tags
will be displayed for the connection.
