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.
