Safety Master function
Up to 32 connections can be used.
4-4
Specifying the safety I/O
communications status
after a communications
error occurs
The user can specify one of the following conditions for safety I/O com-
munications after a communications error occurs.
• Automatic reset (earlier versionís function)
• Stop only the connection where the error occurred.
• Stop all connections
4-4
Restarting I/O communi-
cations that were stopped
due to a communications
error
When safety I/O communications have been stopped due to a communi-
cations error, the I/O communications can be restarted from the Network
Configurator or the logic program.
4-4

When the Controller is operating as a Safety Slave or Standard Slave with
inputs, the following data can be attached to the send data.
• Local input monitor
• Local output monitor
4-3
