5 GRT1-ECT Procedures
5 - 8 GRT1-series EtherCAT Communication Unit - Operation Manual
 Replacing a Unit
1
Turn OFF the I/O power supply if required for your application.
2
Release the locks on the front of the SmartSlice I/O Unit that must be replaced and
remove the terminal block. The wiring can remain connected.
3
Remove the main block of the SmartSlice I/O Unit and replace it with a new SmartSlice
I/O Unit of the same type.
4
Mount the terminal block that was removed in step 2 and latch the lock that was released.
5
When the power is turned ON again, the Communication Unit will automatically detect
the Unit that was replaced and download the backup data. The SmartSlice I/O Unit’s TS
indicator will indicate the results of the restore operation.
•
If the download was successful, the Unit will be reset automatically and join I/O
communication normally. The I/O Unit’s TS indicator will be lit green.
• If the download failed, the I/O Unit’s TS indicator will flash red.
• If the connected Unit is the wrong model, the I/O Unit’s TS indicator will be lit red.
Precautions for Correct Use
• Do not turn OFF the power supply or reset the EtherCAT Communication Unit while data is
being restored. The data will not be restored properly if the power is turned OFF.
• When an I/O Unit has been replaced with the power ON and the new I/O Unit joins I/O
communication, the new Unit will be compared to the previous one and the parameter data
restore operation will start automatically. While data is being restored, the EtherCAT
Communication Unit’s TS indicator will flash green every 0.5 s. The TS indicator will stop
flashing (not lit) when the restore operation is completed. If the restore operation fails, the
Automatic Restore Monitor Flag (bit 13 of the Communication Unit status flags) will be turned
ON and the Communication Unit’s TS indicator will be lit red for 2 s.
When one of the SmartSlice I/O Units connected to the EtherCAT Communication Unit must be
replaced, the Unit can be replaced without turning OFF the power. The Units can be replaced online
because the SmartSlice I/O Units are made up of 3 blocks: the base block, main block, and terminal
block. When replacing a SmartSlice I/O Unit, leave just the base block connected and replace the main
block. I/O communication will continue with the other I/O Units even while the problem Unit is being
removed and replaced.
5-2-9 Online Replacement Function
