Notes on addressing

<C_ID> Channel or channel ID starting with 1

<A_ID> Axis ID starting with 1

<S_ID> Spindle index starting with 0. The spindle index is a component part of the index group.

Addressing modes of "IndexGroup"

The index group can be specified for the CNC objects of channels and axes both with “logical” and “index-based” addressing.

“Logical” addressing is selected by the additional bit 0x100000. If this bit is missing, access to the objects is index-based. The example below shows the significance of this bit.

Spindles are generally accessed index-based and the index entry is a component part of the index group. For example, 0x25302 for the index group of the third spindle.

Example: There are only two channels with logical numbers 1 and 5.

	Channel “1”	Channel “6”
Logical access	IdxGrp = 0x121301	IdxGrp = 0x121306
Index-based access	IdxGrp = 0x21301	IdxGrp = 0x21302

It is advisable to use the logical access. The advantage here is that access to channel 6 remains unchanged if channel 1 is deactivated. With index-based access, the index group of channel 6 changes from 0x21302 to 0x21301 in this case and it becomes the ‘first’ channel.

Notice

It is advisable to use the logical access.
