Versions 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.

1 Restrictions on Firmware Update Restrictions This section describes restrictions on the user programs and SD Memory Cards. User Programs Updating the firmware initializes the existing data such as various settings, user program, and varia- bles in the CPU Unit. The CPU Unit data initialized by the firmware update and the CPU Unit data retained are shown in the table below.
Page 27
1 Restrictions on Firmware Update Precautions for Correct Use When you reuse the existing various settings, user program, and values of variables in the CPU Unit, make sure to back them up before updating the firmware, and restore them after the up- date.

2 Performing Firmware Update Procedures to Perform Firmware Up- date This section describes procedures assuming that you finished creating the Memory Card for updating firmware. The procedures to perform firmware update are as follows. If you do not want to reuse the existing various settings, user program, and variables in the CPU Unit after the firmware update, proceed from step 2.
