3-2 GRT1-ECT Features
The GRT1-ECT EtherCAT Communication Unit controls data exchange over the EtherCAT network
between the EtherCAT Master and SmartSlice I/O Units.

Manage Multiple SmartSlice I/O Units as One Slave
A single EtherCAT Communication Unit with up to 64 connected SmartSlice I/O Units can be
managed as a single slave device from the EtherCAT Master.

I/O Data Exchange
Cyclic I/O data exchange is used to exchange I/O data between the EtherCAT Master and
SmartSlice I/O Units through the EtherCAT Communication Unit. In addition to I/O data, various
status information in the EtherCAT Communication Unit can be accessed from the EtherCAT Master
Unit.

Simplified Startup
The EtherCAT Communication Unit can be set up easily, just by wiring the Unit, setting the EtherCAT
node address on the Unit’s rotary switches, and making simple DIP switch settings.
The Unit’s configuration is read automatically when the power is turned ON and I/O is also
automatically allocated in the SmartSlice I/O Units. It is not necessary to make any settings with a
special Programming Device.

Simplified I/O Wiring
All of the SmartSlice I/O Units that connect to a EtherCAT Communication Unit are equipped with
screw-less clamp terminal blocks. Wiring to external I/O is accomplished just by inserting the wire
into the terminals, eliminating the need to tighten terminal screws.

Table Registration
The configuration of the SmartSlice I/O Units (mounting order and I/O size) connected to a
EtherCAT Communication Unit can be registered in a table by simply setting the corresponding DIP
switch. Once the table has been registered, the actual configuration is compared to the registered
configuration each time that the Unit power is turned ON.
If the configuration does not match, a status flag is turned ON in the EtherCAT Master to indicate the
error.

Hot-swap Replacement of I/O Units
The SmartSlice I/O Unit's consist of three parts that can be separated from each other: Base block,
Main block and Terminal block. You can leave the Base block connected to the Slice I/O Terminal
with power supplied to the Slice I/O Terminal and then replace the Main block or Terminal block.

Automatic Device Replacement
The Automatic Device Replacement (ADR function) is the mechanism to backup and restore
parameters with only a DIP switch setting on the Communication Unit.
Setting a DIP switch will back up parameters in the I/O Unit to the EtherCAT Communication Unit.
Another DIP switch will write the backed-up parameters from the EtherCAT Communication Unit to
the new I/O Unit.
