SmartSlice I/O Unit Number Allocation

32
In order to identify the PROFIBUS Communication Unit on the PROFIBUS
network, it needs to be assigned a unique station address. Using this address
the PROFIBUS Master Unit can transfer parameter settings and exchange I/O
data. The PROFIBUS station address is assigned using the rotary switches
on the front of the Unit.
Similarly, the individual SmartSlice I/O Units need a unique address to identify
each of them to the GRT1-PRT Unit. Contrary to the GRT1-PRT Unit, the indi-
vidual SmartSlice I/O Unit addresses are assigned automatically at startup.
The station address of the PROFIBUS Communication Unit Slave is set with
the rotary switches on the front of the PROFIBUS Communication Unit.
The left rotary switch sets the ten's digit, and the right rotary switch sets the
one's digit.

The valid address range is 00 to 99 can be set as long as this number is not
set on another station (Master or Slave) in the network. However, the following
must be observed.
selecting the GRT1-PRT Station address to be 0, it will be able to exchange
I/O data over PROFIBUS, but it will not be possible to upload / download
parameters or status information.
1. Always turn OFF the PROFIBUS communication power supply and
PROFIBUS Communication Unit's power supply before setting the station
address.
2. The factory default setting for the station address is 00.
3. If the station address is duplicated on another station, communication will
not be achieved.
The SmartSlice I/O Unit numbers are used to identify the individual I/O Units
in the SmartSlice system. These unit numbers are assigned automatically at
startup, when the power is turned ON. The numbering starts from #1 and runs
from left to right. It is not necessary for the user to set these numbers.
