1-1 Overview of GRT1-Series SmartSlice I/O Units
The GRT1-Series SmartSlice I/O Units are building-block style I/O devices,
which can be expanded in small I/O increments. This provides the possibility
to configure I/O systems which exactly match the various customer applica-
tions. SmartSlice I/O Units communicate with the PROFIBUS DP-V1 Master
Unit by remote I/O communication through a PROFIBUS Communication
Unit. The figure below shows a typical I/O configuration.
SmartSlice I/O configurations can be very compact, consisting of only a few
I/O points, but they can also be extended, to up to 64 I/O slices. The slice con-
figuration can also be subdivided over two or more blocks using local exten-
sion units and extension cables, as shown in the figure above.
GRT1-Series SmartSlice
I/O Units The GRT1-Series of SmartSlice I/O Units and Communication Units is con-
stantly being expanded with new Units. Refer to the latest revisions of the
GRT1 Series SmartSlice I/O Units Operation Manual (W455) and the GRT1-
DRT DeviceNet Communication Unit Operation Manual (W454) for currently
available units in the GRT1-Series.
