Page 36: Regulations And Standards
Concepts  EMC Directive OMRON devices that comply with EU Directives also conform to the related EMC standards so that they can be more easily built into other devices or the overall machine. 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 37 The NJ-series Controllers comply with the following shipbuilding standards. Applicability to the ship- building standards is based on certain usage conditions. It may not be possible to use the product in some locations. Contact your OMRON representative before attempting to use a Controller on a ship.
Page 38: Versions
Versions Versions Hardware revisions and unit versions are used to manage the hardware and software in NJ-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.
Page 39 Versions Checking Unit Versions with the Sysmac Studio You can use the Sysmac Studio to check unit versions. The procedure is different for Units and for Eth- erCAT slaves.  Checking the Unit Version of a Unit You can use the Production Information while the Sysmac Studio is online to check the unit version of a Unit.

Page 291: Load Short-Circuit Protection And Line Disconnection Detection For Cj-Series Basic I/O Units
Appendices Load Short-circuit Protection and Line Disconnection Detection for CJ- series Basic I/O Units A-4-1 Load Short-circuit Protection and Line Disconnection Detection for CJ1W-OD202 This section describes the load short-circuit protection and line disconnection detection of the CJ1W- OD202 Output Units. As shown below, normally when the output bit (OUT) turns ON, the transistor will turn ON and then out- put current (Iout) will flow.
Page 292 Appendices Figure 3 Operation for Disconnected Line with Output Current below the Line Disconnection Detection Current A: Load not connected or load line broken. B: Current to load at or below line disconnection detection current. C: Rise of current to load too slow and error detected before the disconnection detection current was reached.
Page 293 Appendices  Programming Example In this example, CJ1W-OD202 is mounted in slot 0 of rack 0. This example shows how to change output Jxx_Ch0_Out00 to FALSE immediately if the Alarm Out- put Bit _CJB_IOUnitInfo[0,0,0] changes to TRUE and how to keep the output FALSE until the cause is removed and the bit is reset with RstOD202.
Page 294: A-4-2 Load Short-Circuit Protection For Cj1W-Od204/Od212/Od232/Md232
Appendices A-4-2 Load Short-circuit Protection for CJ1W- OD204/OD212/OD232/MD232 As shown below, normally when the output bit turns ON (OUT), the transistor will turn ON and then out- put current (Iout) will flow. If the output current (Iout) exceeds the detection current (Ilim) when an over- load or short-circuit occurs, the output current (Iout) will be limited as shown in Figure 2.
Page 295 Appendices  Restrictions If a short-circuit occurs in an external load, immediately turn OFF the corresponding output and remove the cause. An alarm output bit that corresponds to the external load output number is turned ON. There is an alarm output bit for every common. When an alarm output bit turns ON, use a self-holding bit for the alarm in the user program and turn OFF the corresponding output.
Page 296: Emc Directive Measures For Relay Outputs
Appendices EMC Directive Measures for Relay Outputs The NJ-series Controllers conform to the Common Emission Standards (EN 61131-2) of the EMC Directives. However, noise generated by relay output switching may not satisfy these Standards when the Controller is incorporated into a system. In such a case, a noise filter must be connected to the load side or other appropriate countermeasures must be provided external to the Controller.
Page 297 Appendices Current Circuit Characteristic Required element The varistor method prevents the Varistor method imposition of high voltage between the contacts by using the constant voltage characteristic of the varis- tor. There is a delay in the resetting time. Power supply If the supply voltage is 24 or 48 V, insert the varistor in parallel with the load.
Page 298: System-Defined Variables Related To Hardware
Appendices System-defined Variables Related to Hardware System-defined variables are assigned specific functions by the system. They are registered in the global variable table, or the local variable table for each POU, in advance. The variable names cannot be changed. Some of the variables start with an underbar and some start with ”P_”.
