The INC selections are transferred to the mode group interface. This specification is
activated via the DB10, ... DBX 57.0 (INC-inputs active in the BAG-range) through this block
once after power up.
Furthermore, two machine control panels can be handled in parallel by this block. The
module 2 call for the 2nd machine control panel in OB1 cycle must come after the call of the
1st MCP Support for two MCPs is provided in the control panel blocks up to certain limits
(support is not provided as standard for mutual interlocking of axis selections with identical
assignments on two MCPs).
Flexible axis configuration
It is possible to be flexible in the assignment of axis selections or direction keys for machine
axis numbers.
Better support is now provided by the MCP blocks for the use of two MCPs, which are to run
in parallel, in particular for an application using two channels and two mode groups. Note
that the axis-numbers are also specified in the parameterized mode group number of the
MCP block in the axis tables of the relevant MCP.
For this flexibility there are tables for axis numbers in DB 10.
For the 1. Machine control panel (MCP) the table starts from the byte 8
(symbolic name: MCP1AxisTbl[1..22]) and
for the 2. Machine control panel (MCP) the table starts from the byte 32
(symbolic name: MCP2AxisTbl[1..22]) for the second MCP. The machine axis numbers must
be entered byte by byte here.
It is permissible to enter a value of 0 in the axis table. Checks are not made to find
impermissible axis numbers, meaning that false entries can lead to a PLC Stop.
For FC 24, the maximum possible number of axis selections can also be restricted. This
upper limit is set for the
1. Machine control panel in DB10.DBW30 (symbolic name: MCP1MaxAxis) or for the
2. Machine control panel in DB10.DBW54 (symbolic name: MCP2MaxAxis) for the
respective MCP.
The default setting is 0, corresponding to the maximum number of configured axes. The axis
numbers and the limit can also be adapted dynamically. Afterwards, a new axis must be
selected on FC 24. Axis numbers may not be switched over while the axes are traversing the
relevant direction keys.
The compatibility mode is preset with axis numbers 1 to 6 for both MCPs and restricted to
the configured number of axes.
