Chapter 6 Configure Modules in RSNetWorx for DeviceNet Software
The Multicast connection type enables other safety controllers to read the safety
input data by using this input connection. The Point to Point connection type
does not enable this functionality.
For other safety controllers to use this safety connection to read the input data,
the connections must be identical.
The RPI, connection name, and channel configuration must match so that this
connection can be used by the other safety controller.
Set the Connection Configuration
The safety connection between a controller and I/O module is based on many
items, one of which can be the configuration signature of the safety I/O module.
If the configuration signature must match, the configuration signature must
remain the same once the safety connection is established or the connection is
broken.
To obtain SIL 3 integrity of a Guard I/O module, from the Configuration pull-
down menu, choose ‘Configuration signature must match’. For more information
about the configuration signature, refer to
