Hello everyone,

I have one problem. I use B&R CNC system. To define zero point of G54 / G55 / G56 and G57, i create zero point table which named ZeroPoint.zpt. So far, its working good. But the problem is, if i need to change for example G54, X axis position, i can not do it in HMI. I can not find the correct way to do this. Everytime when i need to change origin of G54 ..... G57, i have to connect with my computer via Automation Studio, and change zero point table and upload it to PLC.
It's not effective. For any small change, every time, I have to go to the customer area and do this. On the customer side, its completely not effective.

Anyone do this before? My local B&R office can not help me about that. They didn't figure it out how to do it also.

Hi.

I have implemented such a function, but that was in 2007 with AS 2.6
Can you give a little more information about your application? As-Version? Arnc0-version? Any options like Mapp or generic motion control? Which kind of Hmi are you using? Where is your ZP-Table stored? Persistent-Ram? Data object? File?

I was using a plain Arnc0 system and had stored ZP-Table, R-Parameter and so on in a data-object. It has been loaded from the memory card at startup or with a trigger, copied to a structure that could be sent to the cnc-core and taken over by an NC-action.
The Hmi had to be programed by myself.

Hello,

I'm using AS 4.7. For cnc, using Arnc0 system for 4 axis movement. Defined MpCNC4Axis function block, and use zero point table as data object with MpCNC4AxisParType.

Here is the screenshot of my zeropoint define line on ST.



I have one idea but its not simple enought to be healty solution. ZeroTable.Zpt actually is a .xml file. I can read and edit that .xml file but i say again, its not simple solution.
Almost every CNC controller has very simple solution to change origin. Not having on B&R is not logic to me. I believe there is one function block for this but after several days i can't find it. Also my local B&R office can't find it. Really seems weird to me.
