isoActHDNo (C, S)

$P_ISO2_HNO[n]

Active tool offset number in ISO mode

The following applies to rows 1- 4:

This value is only practical if ISO2 mode is permissible.

This value contains the H number of the tool length offsets in the 3 geometry dimensions in rows 1 - 3 and the D number of

the tool radius offset.

If H99 is programmed, then

all 3 geometry dimensions (=rows 1-3) have the value "-1"

the radius (= row 4) has the value "-1"

If H=D ($MN_EXTERN_TOOLPROG_MODE,Bit6=0), then these variables contain the last programmed D or H.

If an offset D > 1 is selected in Siemens mode, all rows have the value "-2".

If ISO2 mode cannot be activated ($MN_MM_EXTERN_CNC_SYSTEM != 4), the variable has the value=-3.

The following applies to row 5:

This value is only practicable if ISO3 mode is permissible.

This value contains the current number of tool offsets in ISO3 mode.

If an offset D > 1 is selected in Siemens mode, the value "-2" is returned.

If ISO3 mode cannot be activated ($MN_MM_EXTERN_CNC_SYSTEM != 5), the variable value =-3.

Return value

-3: ISO2 or ISO3 mode inactive

-2: Siemens offset selected with D > 1.

-1: H99 programmed in ISO mode, Siemens offset D1 active

toolFrameState (C, S)

Info about tool orientation in the work

toolFrameState provides bit-coded information about whether the PI service _N_SETUDT with the function designations 12 and

13 can be activated in its current state and also specifies any parameters that may be required:

Bit 0 provides information about whether the NCK can generate a tool frame with PI service _N_SETUDT and function desig-

nation 12 in its current state. Once the bit is set, the NCK receives information about the current tool orientation, i.e. either a

tool holder that can be oriented or an orientation transformation is active and the tool frame can be generated.

Bit 1 provides information about whether, in its current state, the NCK has stored data for the restoration of the program

environment (bit 1 = 1), which can be restored using PI service _N_SETUDT and function designation 13.

When bit 0 is set, bit 2 provides information about whether the tool axis corresponds to a geometry axis of the current WCS:

Bit 2 = 0: The tool axis does not correspond to any geometry axes of the current WCS. In this case, bit 3 / bit 4 provide the number

of the geometry axis next to the tool axis. Bit 5 provides the retraction direction of this axis (plus/minus). This information can

be displayed by the HMI as a suggestion or default setting for the retraction axis.

Bit 2 = 1: The tool axis corresponds to a geometry axis of the current work. In this case bit 3 / bit 4 provide the number of this

geometry axis, and bit 5 provides its retraction direction (plus/minus).

Return value

Bit 0:

0: PI service _N_SETUDT with function designation 12 disabled

1: PI service _N_SETUDT with function designation 12 enabled

Bit 1:

0: PI service _N_SETUDT with function designation 13 disabled

1: PI service _N_SETUDT with function designation 13 enabled

Bit 2

0: Tool axis does not correspond to any geometry axes

1: Tool axis corresponds to a geometry axis

Bit 3 / Bit 4:0: Function not active

1: Tool axis in the 1st geometry axis

2: Tool axis in the 2nd geometry axis

3: Tool axis in the 3rd geometry axis

Bit 5:

0: Retraction direction plus

1: Retraction direction minus

acMToolLengthIndex (C, S)

$AC_M_TOOL_LENGTH_INDEX

Assign. tool length components for milling tools

The variable returns the number of the tool length components (1, 2 or 3 corresponding to the length components L1, L2, L3)

for milling tools, which is assigned to the geometry axis that was transferred as an index.

In this context, milling tools are all tools with a tool type that does not lie between 400 and 599.

The assignment does not take into account any rotations (e.g. by kinematic transformations) or frames. It depends on the active

plane and the setting data SD42950 $SC_TOOL_LENGTH_TYPE and SD42940 $SC_TOOL_LENGTH_CONST.

If the tool length component is active with a negative sign, the index is output with a negative sign. This can be the case if the

hundreds digit of setting data SD42940 $SC_TOOL_LENGTH_CONST equals 1.

Length component assignment for active tool

The variable returns the number of the tool length components (1, 2 or 3 corresponding to length components L1, L2, L3) of

the active tool, which is assigned to the geometry axis that was transferred as an index.

The assignment does not take into account any rotations (e.g. by kinematic transformations) or frames. It depends on the type

SEGA: Extended state in the WCS

OEM-MMC: LinkItem /Channel/GeometricAxis/...

All status data that are dependent on machine movement and specified in the workpiece coordinate system are

combined in module SGA. Supplementary information can be found in module SEGA. The individual variables are

defined as arrays where the line index is the number of the axis (assigned to the current channel).The variable

"name" in module SGA with the line index in question identifies the axis.

The assignment of the line indices in modules SGA and SEGA is identical.

With SW 5.2 and later, OPI modules SGA and SEGA can be addressed via the geo-axis no. instead of via the channel

axis no.:

Line index 1001: 1st geo-axis

Line index 1002: 2nd geo-axis

Line index 1003: 3rd geo-axis

The number of channel axes (geometry, special axes and spindles) can be found in "$$numMachAxes" in module

Y in area C.
