Siemens SINUMERIK 840D sl Function Manual page 1051

To provide this flexibility, tables for axis numbers are stored in DB10.
For the 1st machine control panel (MCP) the table starts at byte 8 (symbolic name:
MCP1AxisTbl[1..22]) and for the second machine control panel (MCP) starting at byte 32
(symbolic name: MCP2AxisTbl[1..22]) for the second MCP. The machine axis numbers are
entered here bytewise. It is permissible to enter a value of 0 in the axis table. Checks are not
made to find illegal axis numbers, meaning that false entries can lead to a PLC Stop.
The restriction of the possible number of axes at FC25 is realized using the 0-values in the
axis table. The axis numbers can also be adapted dynamically. During the manual traversing
of axes using the direction keys, the axis numbers must not be switched over. The compatibility
mode is preset with axis numbers 1 to 4 for both MCPs and restricted to the configured number
of axes.
