Replacement Precautions
The PROFIBUS Communication Unit is a Network device. If the Unit is dam-
aged, it will effect the entire Network, so always ensure repairs are under-
taken immediately. It is recommended to have a spare PROFIBUS
Communication Unit on hand so that repairs may be conducted quickly.
Replacement Precautions
Observe the following precautions when replacing the Unit.
• Always turn OFF the power before replacing the Unit.
• Ensure that the new Unit is not faulty.
• If a poor connection is suspected of causing the malfunction, clean the
connectors using a clean, soft cloth and industrial-grade alcohol. Remove
any lint or threads left from the cloth, and remount the Unit.
• When returning a faulty Unit for repair, always attach a detailed fault
report to the Unit and return it to the nearest OMRON dealer.
Note
1.
In order to prevent faulty operation be sure to turn off the power to all mas-
ter and slave devices before replacing the Unit.
2.
When replacing the Unit, do not reconnect it to the Network before carrying
out the procedures listed below.

Setting the Unit after Replacement
After replacing the Unit - before re-applying the power - set the Profibus sta-
tion address number to the same value as the previous Unit.
After re-applying the power, the Profibus configuration settings will be auto-
matically set by the Profibus Master. No user actions required.

tion
2.

execute these operations again for the new Unit.
Re-connect it to the network, and restart operation.
