[?]: FM 353 and Refference Point Approach program

[ivanpagac]

Hi there,
Iam working with FM 353 and Iam programming it for Refference Point Approach. Iam really new in this.
Here is my problem:
I dont know, how to modify programmable (from FC or OB block) values in machine data block saved on FM 353.
My goal is to set up new values for module from operator panel.
for example new refference point accordinates or set up new speed or ... i am able to do it in JOG mode, bud iam really desperate how to modify RPA values.
I leaf through manual thousant-times but i dont know how to do that.
Can you help me? If it helps,
I'll post my code here.
