"Values recording in an array" instruction

This instruction is used to record the value of a user variable for several cycles of a program.

It is possible to register three types of variables: LREAL, REAL or DINT.

You can use this instruction only once per program and save a maximum of 20 values. (20 program cycles)

These values are returned in an array that is part of the user variables.

Use of the instruction

To start, you must create an array type user variable followed by the type of variable you want to save. (see figure 1)
