14.2 Machine data access via part program
With the HMI, the designation of the machine data is displayed. The internal
data designation requires further identifiers. If the machine data is modified by
programming or read in via the serial port, then these identifiers must be
specified.
$MM_ Display machine data (operating panel data)
$MN_/$SN_ General machine data/setting data
$MC_/$SC_ Channel-specific machine data/setting data
$MA_/$SA_ Axis-specific machine data/setting data
$MD_ Drive machine data
Where: $ System variable
M Machine data
S Setting data
M, N, C, A, D Partial area (second letter)
Axis data is addressed via the axis name. The internal axis designation (AX1,
AX2 ... AX5) or the designation specified via MD 10000: AXCONF_NAME_TAB
may be used as the axis name.
e.g.: $MA_JOG_VELO[Y1]=2000
The JOG speed of axis Y1 is 2000 mm/min.
If the contents of the machine data is a STRING (e.g. X1) or a hexadecimal
value (e.g. H41), then the content must be given between “ ‘ ” (e.g. ‘X1’ or
‘H41’).
e.g.: $MN_DRIVE_INVERTER_CODE[0]=‘H14‘
FDD module 9/18 A at drive slot 1 of the drive bus.
To address the various contents of a machine data, identifying data must be
specified in square brackets.
e.g.: $MA_FIX_POINT_POS[0,X1]=500.000
axis X1 is 500The 1st fixed point position of
(0=1st, 1=2nd, 2=3rd etc.)
$MN_AUXFU_GROUP_SPEC[2]=‘H41’
Time at which the auxiliary functions of the 3rd auxiliary function group are
output.
$MN_AXCONF_MACHAX_NAME_TAB[0]=‘X1’
Name of the 1st machine axis is X1.
$MA_REF_SET_POS[0,X1]=100.00000
The 1st reference point value of axis X1 is 100 mm.
Assignment of channel-specific machine data:
CHANDATA(1) Assignment for channel 1
$MC_CHAN_NAME=‘CHAN1’ Channel name for channel 1
$MC_AXCONF_GEOAX_NAME_TAB[1]=‘Y’ Name of the 2nd geometry
axis on channel 1 is Y
...
R10 = 33,75 R10 of channel 1
