The configuration of the SmartSlice I/O Units (mounting order and I/O size)
connected to a PROFINET IO Communication Unit can be registered in a
table simply by setting a DIP switch. Once the table has been registered, the
actual configuration is compared to the registered configuration each time that
the power is turned ON. If the configuration does not match, a status flag is
turned ON in the PROFINET IO Controller to indicate the error.
The SmartSlice I/O Unit's circuit section can be removed, so it is not
necessary to turn OFF the Communication Unit's power to replace a Unit.
Communication can be maintained in the remaining (connected) Units.
Before replacing a SmartSlice I/O Unit for maintenance, the parameter data
set in all SmartSlice I/O Units can be backed up in the PROFINET IO
Communication Unit by toggling a DIP switch. Another DIP selects the mode
to automatically write the back-up parameter data to the replacement
SmartSlice I/O Unit.
The PROFINET IO Communication Unit connects to the IO Controller by an
Ethernet network cable and it connects to the SmartSlice I/O Units by directly
coupling the Units together.
The I/O Unit data in the PROFINET IO Communication Unit is shared with the
IO Controller's Input and Output Areas through the PROFINET IO network.
The I/O Units' data is collected in the PROFINET IO Communication Unit and
exchanged with the IO Controller cyclically.
The GRT1-PNT PROFINET IO Communication Unit also supports messaging
services using FINS/UDP, allowing the user to send acyclic message
commands addressed to the GRT1-PNT Unit or individual SmartSlice I/O
Units. This can be sent from the PLC or for instance the Personal Computer.
Always install an End Unit on the last I/O Unit in the system. For the
PROFINET IO Communication Unit there are two options:
/i
Type I/O points
End Unit --
Memory 2 input bits
End Unit
In case of replacement of the PROFINET IO Communication Unit, the
PROFINET IO Device Name will be restored from the GRT1-END-M Unit to
the new Communication Unit. In case of the standard GRT1-END, additional
configuration
replacement.
Note 1 Unlike the standard End Unit, the Memory End Unit will count as one SmartSlice I/O
Unit. Up to 63 SmartSlice I/O Units can be connected to one PROFINET IO Com-
munication Unit when the GRT1-END-M is used.
2 The GRT1-END-M Memory End Unit functionality only applies to the PROFINET IO
Communication Unit. Although the Memory End Unit has the basic End Unit funtion-
ality, the Unit is not aimed to be used together with other Communication Units.
