1.1Explanations on the NC variables

1.1.1Introduction

General

The NC variables can be accessed from the user interface or from the PLC via the operator panel interface (OPI).

The structure of the NC variables and their processing is described in the following sections:

See

NC areas (Page 11)

Data blocks (Page 12)

Variable types (Page 14)

1.1.2NC areas

NC areas

The NC variables are organized in data blocks that are assigned to the following NC areas.

Table 1-1	Assignment of the TO areas
Area		NC variable
NC (N)		Contains all variables that apply to the entire NC, e.g.
		●	System data (Y)
		●	Protection areas (PA)
		● G groups (YNCFL), etc.
Mode group (B)		Contains all variables that apply to the mode group, e.g.
		●	Status data (S)

1.1 Explanations on the NC variables

Area	NC variable
Tool (T)	Contains all variables that apply to the tools on the machine, e.g.
	● Tool offset data (TO)
	● General tool data (TD)
	● Tool monitoring data (TS), etc.
	Each tool area (T) is assigned to a channel.
Axis (A)	Contains machine and setting data that applies to the relevant axis or spindle.
	See List Manual 1, Section: Axis-specific machine data
Feed/main drive (V/	Contains machine data or machine data as service values that apply to the
H)	relevant drive.
	See List Manual 2

1.1.3Data blocks

Overview of the available data blocks

The following table contains an overview of available blocks for variables of the NC and their assignment to the individual areas.

Only those data blocks whose variables can be read or written with direct access are represented.

Data blocks whose variables can be freely defined by the programmer (e.g. global user data) are read from the operating software or PLC using other mechanisms.

References

Further information on which data blocks this mechanism is used, can be found in /FB1/ Function Manual, Basic Functions; Basic PLC program (P3).

1.1.4Variable types

Access to an NC variable

In general, the NC variables are stored as structures or arrays of structures (tables) in the areas. This means the following details must be specified in the address for access to an NC variable:

●Area and area number

●Block

●NC variable name (or column number)

●Line number

NC variable type

Generally, a distinction can be made between three variants for the NC variables:

●NC variables that consist of one line

●NC variables that consist of several lines

●NC variables that consist of several columns and lines

Single-line NC variable

A single-line NC variable consists of just a single value. The following information is required to access an NC variable of this type:

●Area (and possibly the area number)

●Block

●NC variable name

Table 1-2	Single-line NC variant type
numMachAxes
Number of available machine axes
-					Word	r
Multi-line: No

Example for reading the number of machine axes in channel 1:

	Parameter Manual, 03/2013, 6FC5397-3CP40-3BA1

NC variable 1.1 Explanations on the NC variables

HMI:

/Channel/Configuration/numMachAxes[u1]

HMI:

P_C_Y_numMachAxes

PLC with NC variable selector:

Area	C[.]
Block	Y
NC variable	numMachAxes
Area number	1

Multi-line NC variable

This NC variable is generally defined as a one-dimensional array. The following information is required to access an NC variable of this type:

●Area and possibly the area number

●Block

●NC variable name

●Line number

Table 1-3	Multi-line variant type
actFeedRate			$AA_VACTB[x]				S5
Actual axial feed value (only when		the axis is a positioning axis, "spec" = 1)
%						Double	r
Multi-line: Yes			Axis index		numMachAxes

Example for reading the current speed of axis 3 in channel 1:

HMI: /Channel/MachineAxis/actFeedRate[u1, 3]

HMI: P_C_SEMA_actFeedRate

PLC with NC variable selector:

Area	C[.]
Block	SEMA
NC variable	actFeedRate[.]
Area number	1
Line	3

Multi-line and multi-column NC variable

This NC variable is generally defined as a two-dimensional array. The following information is required to access an NC variable of this type:

Compensation value parameters		for a tool edge
mm, inch or user-defined		0			Double		wr
Multi-line: Yes		(EdgeNo - 1) * numCuttEdgeParams +		numCuttEdgeParams * numCuttEdges
		ParameterNo

Example for reading and writing the current cutting edge data of cutting edge 3 / parameter 1 of tool 3 in T area 1. In the example, it is assumed that each tool cutting edge is defined with (numCuttEdgeParams =) 25 parameters:

HMI: /Tool/Compensation/cuttEdgeParam[u1,c3, 51]

HMI:

P_T_TO_cuttEdgeParam

PLC with NC variable selector:

Area	T[.]
Block	TO
NC variable	cuttEdgeParam[.]
Area number	1

Bit 7=1:		Tool adapter data sets are available.
Bit 8=1:		Total offsets are available.
Bit 9=1:		Tools in a turret are handled in OPI variable modules such that they are not "displayed" in
		tool half-locations, but always displayed in a turret location. Please note, therefore, that
		tools in a turret remain (in display terms) in their turret location in the event of a tool
		change.
Bit 9=0:		Default response; Tools in a turret are "displayed" in the OPI in their actual (according to
		data) location.

maxNumSumCorr	$MN_MM_NUM_SUMCORR
Total number of total offsets in NCK
A setting of -1 means that the number of total offsets equals the
number of edges * number of total offsets per edge.
A setting of > 0 and < number of edges * number of total offsets per edge
means that a maximum number of total offsets equalling "number of total
offsets per edge" can be defined per edge, but need not be, i.e. it is thus
possible to use the buffer memory more economically.
In other words, only the edges have a total offset data set for which
data can be defined explicitly.
