Motion Block Control Word
The motion block control word identifies the block as a motion block,
specifies the number of motion segments defined in the block, and
indicates whether or not it contains a programmable I/O control word. (See
Figure 9.3.) Nineteen motion blocks must be downloaded to the module to
configure all 114 motion segments.

Number of motion

10 Axis 2
11 Both Axes
000000001
Programmable
I/O control word:
0 = No
1 = Yes
Bit 4 - Programmable I/O Word
If you want to configure the programmable I/O, set this bit to 1 to indicate
to the module that a programmable I/O control word is appended to the end
of the motion block. If you do not specify I/O control information, a
default configuration is used.
Bit 8 - Axis 1
Set this bit to 1 if the motion block applies to axis 1.
Bit 9 - Axis 2
Set this bit to 1 if the motion block applies to axis 2.
Important: If bits 8 and 9 are both set, the motion block applies to both
axes and a single block transfer of a new motion block will update the
module’s internal motion segment data table for both axes.
