４ - ３ Add Devices In this project file, it is necessary to register the safety CPU to be monitored. There are two methods: adding as an external device and as an internal device. NA can monitor multiple safety CPU units. The maximum number of registrable units is 16, including controllers to which the safety CPU is not connected. This section describes how to add devices to another project. If there is no need to communicate between a CPU unit and NA except monitoring a safety PLC, such as demonstrations, you don't have to set the IP address to add a safety CPU unit. This is a recommended method. 18 4-3-1 Add External Devices 1. Right-click [Config/Setting] – [Device Reference].
Then Left-click [Add] – [External Device]. 2. ExternalDevice0 is added. Double-click it. 3. Click [Device] and select NX-CSG320. Note: NX102, NX7, and NJ are also selectable. 4. Enter the IP address. Now you have added the safety CPU unit that you want to connect.
