The following procedure shows the basic steps required before using the
PROFIBUS Communication Unit and the SmartSlice I/O Units.
1. Mount the GRT1-PRT Unit and the SmartSlice I/O system on the DIN rail
The maximum number of SmartSlice I/O Units can be 64.
2. Wire the SmartSlice I/O Units and the GRT1-PRT Unit's power supply.
3. Wire the PROFIBUS network, to connect the Unit to the PROFIBUS Mas-
ter Unit.
4. Set the rotary switches on the front of the GRT1-PRT to the desired
PROFIBUS address.
5. Turn ON the power to the Unit and the I/O.
6. Turn ON (from OFF to ON) DIP switch 1 on the front of the PROFIBUS
Communication Unit. When switch 1 is turned ON, the existing SmartSlice
I/O Unit configuration (connection order and I/O size) is registered in the
PROFIBUS Communication Unit as a registered table. After the table is
registered, leave pin 1 ON to enable the table.
Note The next time the power is turned ON, the actual SmartSlice I/O Unit configu-
ration at power on is automatically compared to the registered table. Any
SmartSlice I/O Units that do not match the registered table (connection order
or I/O size) will not participate in I/O communication. I/O communication will
start with the other SmartSlice I/O Units.
Use the following procedure to configure the PROFIBUS Master Unit for com-
munication with the PROFIBUS Communication Unit, using the Cx-Profibus
FDT Container program and the GRT1-PRT DTM:
1. In Cx-Profibus, create a network and define the parameters and I/O con-
figurations for the PROFIBUS Master Unit settings and the allocated slave
devices. Determine the baud rate and the bus parameter setup. Make sure
that the "Go to OPERATE mode "option is selected, to force the Unit to OP-
ERATE mode upon a PLC mode change to RUN / MONITOR mode.
2. Download the network configuration to the PROFIBUS Master Unit. After
downloading the configuration, Cx-Profibus will restart the PROFIBUS DP
Master Unit.
3. After restarting the PROFIBUS DP Master Unit it will automatically start
communication.
