Remote I/O data is collected
from the connected
SmartSlice I/O Units and
exchanged with the Master Unit

The PROFIBUS Communication Unit automatically detects the Master's com-
munication baud rate, so it is not necessary to set the baud rate. (If the Mas-
ter's baud rate has been changed, the PROFIBUS Communication Unit must
be turned OFF and then ON again to change its baud rate.)
The PROFIBUS Communication Unit connects to the Master by a network
cable and it connects to the SmartSlice I/O Units by directly coupling the Units
with slide connectors.
The I/O Unit data in the PROFIBUS Communication Unit is shared with the
Master's Input and Output Areas through the PROFIBUS DP network. The I/O
Units' data is collected in the PROFIBUS Communication Unit and exchanged
with the Master asynchronously.
The GRT1-PRT PROFIBUS Communication Unit also supports messaging
services, allowing the user to send acyclic message commands addressed to
the GRT1-PRT Unit or individual SmartSlice I/O Units.
