Making Sure That SmartSlice Specifications Are Applicable

84
Before you connect the Units and set the parameters, you must select the
SmartSlice I/O Units and be sure that the specifications are applicable.
You select the SmartSlice I/O Units for the numbers and types of I/O that are
necessary.
Refer to the datasheets and manuals for the SmartSlice I/O Units.
This example uses these Units.

CompoNet Master Unit
CompoNet Communications Unit
SmartSlice Input Units
SmartSlice Output Units
End Unit
There are restrictions in the SmartSlice I/O Units which can connect to one
CompoNet Communications Unit. Refer to the table below.
Be sure the SmartSlice I/O Units obey these restrictions.
Item
Number of Smart- 64 maximum (Do not include the End Unit.)
Slice I/O Units
Number of I/O bytes Inputs: 32 bytes maximum (including the status words and bits
which the Units do not use)
Output: 32 bytes maximum (including the bits which the Units
do not use)
Total power con- 80 W maximum per block
