Versions
Hardware revisions and unit versions are used to manage the hardware and software in NJ/NY-series
Units and EtherCAT slaves. The hardware revision or unit version is updated each time there is a
change in hardware or software specifications. Even when two Units or EtherCAT slaves have the
same model number, they will have functional or performance differences if they have different hard-
ware revisions or unit versions.
You can check versions on the ID information indications or with the Sysmac Studio.
The unit version is given on the ID information indication on the side of the product.
