Description

The functionality transfers drive data directly from the drive controller of the field bus to the HLI.

There are 2 options for this:

  1. read and write access using lr_mc_control.uns32_1 to lr_mc_control.uns32_4; here, the parameters from antr.plc_to_drive[i] are used for parameterisation.
  2. data display only using lr_state.uns32_1 to lr_state.uns32_4; here, the parameters from antr.drive_to_plc[i] are used for parameterisation.

4 data items can be transferred in each direction simultaneously, i.e. a total of 8.

Drive data to be transferred

Various data item types can be transferred. The data type must be specified by P-AXIS-00855 or P-AXIS-00863.

Starting with this parameterisation, the drive value is read into the CNC: The data is output on the HLI in a UNS32 variable (UDINT). If the parameterised data is an SGN data type, the sign is transferred to the HLI in bit 32 (counting from 0). It is also possible to read or write individual bits. The data types “BITARRAY_xx” are used for this purpose.

The functionality need not be enabled. Parameterisation in the axis parameter list is sufficient.
