DeviceNet Communications Unit
GRT1-DRT
DeviceNet-compliant Interface Unit with up to 1,024 I/O Points at
One Node
• Connect up to 64 SmartSlice I/O Units.
• Consolidate a large capacity of I/O points into one Slave (up to
1,024 I/O points).
• Save space by configuring different I/O types using one Slave Unit.
• Easily get the system started simply by setting the node
addresses.
• Replace SmartSlice I/O Units online while maintaining
communications. This helps minimize equipment downtime.
• Smart functions for monitoring equipment operating status. This
helps improve preventive maintenance and the utilization rate.
• Registering SmartSlice I/O for planned future expansion
decreases design work when changes are made. (Supported for
unit version 2.0 or higher.)
