GRT1-series EtherCAT Communication Unit - Operation Manual
Reference
•
The presence of Turnback units and cables does not influence the automatic allocation of Unit
numbers.
•
The unit numbers allocated automatically to the SmartSlice I/O Units are unrelated to the
EtherCAT station address set with the rotary switches.
These flags can be used to monitor the status of the connections between the GRT1-ECT and the
SmartSlice I/O Units as well as the status of the SmartSlice I/O Units themselves. The status flags
take up 1 word and the information is transferred to the Master as part of the Input data. The table
below defines the individual bits in the Status word.
