Unit Versions
Hardware revisions and unit versions are used to manage the hardware and software in NJ/NX-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
hardware revisions or unit versions.
Version Types
There are two types of versions. One is unit version and the other is DB Connection Service version.
These versions are managed independently. Therefore, only one of them may be upgraded.
Unit Version
This is the version of hardware and software of Units and EtherCAT slaves. The version is upgraded
at every specification change in the hardware or software. Therefore, the functionality and
performance differ by the versions even in the same model number of Units and EtherCAT slaves.
DB Connection Service Version
This is the version of DB Connection Service implemented in the Database Connection CPU Units.
The version is upgraded at every specification change in the DB Connection Service.
