The actual products have been checked for conformity to EMC standards.* Whether the products conform to the standards in the system used by the customer, however, must be checked by the customer.
  • Page 18 The NJ/NX-series Controllers comply with the following shipbuilding standards. Applicability to the shipbuilding standards is based on certain usage conditions. It may not be possible to use the prod- uct in some locations. Contact your OMRON representative before attempting to use a Controller on a ship.

  • Page 19: Versions

    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 hard- ware revisions or unit versions.

    Appendix Correspondence of NX Bus Events between NX1P2 CPU Units and Slave Terminals Both NX1P2 CPU Units and Slave Terminals support the mounting of NX Units. This means that NX1P2 CPU Units and Slave Terminals are subject to the same errors. However, with the NX1P2 CPU Unit, it is easier to identify the cause of an NX bus error because two or more events with more specific names may correspond to one Slave Terminal event.
