For the FSoE master connections, you can establish bidirectional input and output communica-
tions with a FSoE slave per connection.
• Example of Calculating the Number of Safety I/O Connections
A calculation example of using the combination of the NX-series CPU Units and Safety CPU
Units is given below.

l Calculating the Number of Routable CIP Safety Connections for the NX-
series CPU Unit
You must specify the total number (m+n) of targets that establish connections as an originator (m)
and originators that establish connections as a target (n), which must be set within the maximum
number of routable CIP Safety connections for the Communication Control Unit. If you set the num-
ber that exceeds the maximum number of routable CIP Safety connections, the CIP Safety
Originator Connection Not Established Error (80310000 hex) will occur. In addition, you cannot set
the number which the total number of CIP Safety originator connections and CIP Safety target con-
nections exceeds the number of routable CIP Safety connections.
If a multi-cast connection is opened for multiple CIP Safety originators and connections, the num-
ber of originators that establish connections as a target becomes the number of CIP Safety origina-
tors.
