Registering NX Units in the Unit Configuration Information as Unmounted
Units for Future Expansion (Designing, Commissioning, and Modularity)
You can register any NX Units as unmounted Units in the Unit configuration information. This allows
the following possibilities.
• NX Units for future expansion can be registered in advance. This eliminates the need to change
the user program when the NX Units are actually added. (Designing)
• If certain NX Units are temporarily unavailable, you can still debug the system in advance with the
NX Units that are available. (Commissioning)
• Even if the number of NX Units changes depending on the type of equipment, the user program
does not have to be changed. (Designing and Modularity)
Exporting/importing NX Unit Settings (Designing)
You can use the Sysmac Studio to export and import the NX Unit settings as files. This allows you to
reuse settings from NX Units for other PROFINET Coupler Units or NX Units.
Simplified IO Wiring with Screwless Clamping Terminal Blocks (Commission-
ing)
The PROFINET Coupler Unit and the NX Units use screwless clamping terminal blocks. The use of
ferrules makes wiring an easy matter of inserting them. The screwless design greatly reduces wiring
work.
Fail-soft operation is provided so that the PROFINET Coupler Unit can start or continue IO refresh-
ing only with the NX Units that can operate normally when an error occurs for the Profinet IO Device
Terminal.
You can use fail-soft operation in the following cases.
• When it is dangerous to stop the entire Profinet IO Device Terminal all at once
• To continue the operation of the Profinet IO Device Terminal until the system can be stopped
safely through the user program or user operation
• To not stop all devices, i.e., to continue operation for only some devices
Features That Reduce Equipment Design Work and Commissioning
