Siemens SINUMERIK 840D sl Commissioning Manual

1.9.8 Channel-specific machine data
If no channel number is defined in the address token, access is always to the currently set
channel of the operating software.
If it is necessary to read data from a specific channel, the identifier u (Unit) with the desired
channel number in square brackets is added to the address. In an array-addressing, the
channel definition is the last argument in the square brackets.
Example:
$MC_RESET_MODE_MASK
or
$MC_AXCONF_GEOAX_ASSIGN_TAB[0]
$MC_RESET_MODE_MASK[u1]
or
$MC_AXCONF_GEOAX_ASSIGN_TAB[0, u1]
$MC_RESET_MODE_MASK
