L_MC2P_TappetRefFromFile

This FB reads a tappet file (*.lct) and provides the data of the application.

Cyclic call by the Lenze Cam Editor

The L_MC2P_Tappet_Ref object created automatically by the Lenze Cam Editor in the "ProfileReference" directory corresponds to an instance of the FB L_MC2P_TappetRefFromFile .

The L_MC2P_Tappet_Ref object or the instance of the FB L_MC2P_TappetRefFromFile

  • is an interface of L_MC2P_Tappet_Ref type
  • can be directly connected to an input of L_MC2P_Tappet_Ref type of another FB, e.g.
    Programming example:
    L_MC2P_TappetRegister1.TappetTable:= L_MC2P_TappetRefFromFile1

Note!

The renewed reading of a file, e.g. FB L_MC2P_TappetRegister , is not possible if the same tappet file is current being processed.

Memory location of tappet data

  • After a Download or an Online Change , the tappet data are only provided in the "/Temp/ProfileData" PLC directory.
    • By switching the PLC off at this time, the tappet data are lost.
  • Only when the boot project is generated, the tappet data are copied into the
    "/IPC/PLC/ProfileData" directory and are then protected against data loss, e.g. on an SD card, even if the PLC is switched off.

Cyclic call by the Lenze Cam Editor

The FB has to be called cyclically if

  • a new tappet file is to be imported while the application is running or
  • the currently connected tappet file has to be updated (new download via the »PLC Designer«).

The FB does not have to be called cyclically if

  • the L_MC2P_Tappet_Ref object is only connected with one tappet file and
  • no update is carried out while the application is running.
