Posted 30 Apr 2018 Hello everybody, I did a search on this item but with no results, so... I am programming with GX developer, an a1scpu. In the program I use the Z and V index register to move some value in D's. But..today I saw dat these Z and V were already in use, ( made by a predecessor,) so I tried Z1 and V1 instead, but with no succes; I got an error: Device setting is wrong.The following causes maybe responsible: An unusable device has been desinated. Index modification,module specification setting is wrong. Special function module device,link direct device setting is wrong. I guess that the a1scpu does not support Z... and V... --- Q: Is this the case, or am I doing something wrong? Many thanks! Share this post Link to post Share on other sites
Posted 1 May 2018 (edited) You have an A1S so you only have one V and Z. Just move your current Z value to a D and mov it back in the end. Also store it your Z value so you can move it back when this sequence starts again Edited 1 May 2018 by Gambit 1 person likes this Share this post Link to post Share on other sites
