restrictions
This is the installation orientation of the Unit. Any restrictions to specifications
that result from the installation orientation are also given.
*1. Refer to 5-4-3 Calculating the Number of Connections on page 5 - 20 for how to calculate the number of
connections.
*2. The number of CIP Safety connections that can be actually set depends on the maximum number of routa-
ble CIP Safety connections of the NX-series CPU Unit.
For NX102 CPU Units, the maximum number of routable CIP Safety connections is 16.
