Address of first object to read

The possible objects are of the DINT type:

  • variables,

  • constants,

  • immediate value.

NOTE: if you enter a constant, an entry field appears to enter the constant. If you enter a variable, this can be located or not.

Number of consecutive objects to read

The possible objects are of the INT type:

  • variables,

  • constants,

  • immediate value.

NOTE: if you enter a constant, an entry field appears to enter the constant. If you enter a variable, this can be located or not.

Reception zone

The reception zone is an integer array. The size of this array depends on the number of objects to read. This integer array can be located or not.
