indexing a1scpu

[Reinier 0]

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!

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
