    Appendices A-4 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 output current (Iout) will flow.
  • Page 325 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 326 Appendices  Programming Example In this example, CJ1W-OD202 is mounted in slot 0 of rack 0. This example shows how to change output Jxx_Ch1_Out00 to FALSE immediately if the Alarm Output 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 ResetOD202.

    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 output current (Iout) will flow. If the output current (Iout) exceeds the detection current (Ilim) when an overload or short-circuit oc- curs, the output current (Iout) will be limited as shown in Figure 2.
  • Page 328 Appendices  Restrictions If a short-circuit occurs in an external load, immediately turn OFF the corresponding output and re- move 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.

  • Page 329: Emc Directive Measures For Relay Outputs

    Appendices A-5 EMC Directive Measures for Relay Outputs The NJ-series Controllers conform to the Common Emission Standards (EN 61131-2) of the EMC Di- rectives. 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 330 Appendices Current Circuit Characteristic Required element Varistor method The varistor method prevents the im- position of high voltage between the contacts by using the constant voltage characteristic of the varistor. There is a Power supply delay in the resetting time. If the supply voltage is 24 or 48 V, in- sert the varistor in parallel with the load.

    Appendices A-6 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_".
