4.8.2 SmartSlice I/O mapping
The I/O data of the SmartSlice I/O Units is transferred to the TJ2-MC64
controller. Then the data is automatically mapped in the I/O memory of the
TJ2-MC64. The mapping is determined by:
• The type of the SmartSlice I/O Unit
• The order of the SmartSlice I/O Units
The I/O data from GRT1-ML2 units is mapped in the TJ2-MC64 in order of
the GRT1-ML2 addresses. For example, the I/O data of a GRT1-ML2 unit
with address 67 hex is mapped before the I/O data of a GRT1-ML2 unit with
address 68 hex.
The TJ2-MC64 allocates digital I/O points in blocks of 32 points.
Note
The GRT1-ML2 does not support the on-line configuration of
SmartSlice I/O Units. However, other communications units can
change the parameters of a SmartSlice I/O Unit and store this con-
figuration in the SmartSlice I/O Unit.
Note
If the GRT1-ML2 configuration contains non-supported SmartSlice
I/O Units or SmartSlice I/O Units configured to consume a non-
default amount of I/O data, the MECHATROLINK-II connection to
the GRT1-ML2 is refused, and it cannot be operated.
Note
The automatic I/O mapping of SmartSlice I/O Units in the exam-
ples given below assumes that each SmartSlice I/O Unit has the
default I/O memory settings.
