Calculating the Number of Connections

Calculating the Number of Safety I/O Connections for the Safety CPU Unit
You must specify the total number of CIP Safety originator connections, CIP Safety target connec-
tions, and FSoE master connections, which must be set within the number of safety I/O connec-
tions that you can set for the Safety CPU Unit. You cannot set the number that exceeds the number
of safety I/O connections that you can set.
Precautions for Correct Use
There is a restriction on the data size that can be communicated between the Safety CPU Unit
and the NX Bus Master, as well as the restrictions on the number of Safety I/O connections.
This data size includes exposed variables. Y
ou can check the usage on the Memory Usage
Pane of the Sysmac Studio.
• Counting the Number of CIP Safety Originator Connections
For the CIP Safety originator connections, you can establish a unidirectional input or output com-
munication with a CIP Safety target per connection. Two connections are used to establish bidir-
ectional input and output communications.
•
Counting the Number of CIP Safety Target Connections
CIP Safety target connections have the single-cast connection and the multi-cast connection.
For the single-cast connection, you can establish a unidirectional input or output communication
with a CIP Safety originator per connection. Two connections are used to establish bidirectional
input and output communications.
For the multi-cast connection, you can establish a unidirectional input communication with multi-
ple CIP Safety originators per connection.
