CC Link IE Field - Initialization of remote IO station NZ2GF2

CC Link IE Field - Initialization of remote IO station NZ2GF2

This article describes methods of initialization of CC Link IE Field remote IO stations.
      To read remote input or set remote output of CC Link IE Field remote IO station, you need to initialize it. There are two ways to do that:
            1.      Using remote IO parameters
            2.      Using PLC program

Initialization using remote IO parameters

      Parameter of remote IO station decides which initialization method you need to perform. Remmote IO parameters can be found in CC Link IE Field configuration window. Click on chosen IO module:
PPM -> Online -> Paremeter Processing of Slave Station.



      Initialization method can be changed using Initial operation setting parameter. This parameter can have two values, which means:
  • 0: with initial processing - this setting requires additional initialization from PLC program
  • 1: without initial processing - this setting do not require additional initialization

   
  To write parameter to IO station, you have to choose  Parameter write, prepare parameter pack (parameters cannot have non value). At the end you have to click  Execute Parameter Processing.



PLC Initialization using PLC program


           In PLC program you need to read status of  Initial processing request flag (RWr0.b8) . When module will be ready, you have to set  Initial processing completion flag (RWw0.b8).
