■Manipulating the Rotary Switches for the Node Address with a Precision Screwdriver

Converting from ETN11 Mode to ETN21 Mode

1.Turn OFF the power to the PLC, and set the Ethernet Unit's rotary switches for the node address as follows:

Node address			Indicators
⋅ 161	⋅ 60	RUN	ERC	ERH
0	0	Not lit	Not lit	Not lit

2. Turn ON the power to the PLC. The Unit's indicators will change as follows:

Node address			Indicators
⋅ 161	⋅ 160	RUN	ERC	ERH
0	0	Not lit	Lit	Not lit

3. Set the rotary switches for the node address to 01. There will be no change to the indicators.

Node address			Indicators
⋅ 61	⋅ 160	RUN	ERC	ERH
0	1	Not lit	Lit	Not lit

4. Set the rotary switches for the node address to F1. The RUN indicator will begin to flash.

Node address			Indicators
⋅ 161	⋅ 160	RUN	ERC	ERH
F	1	Flashing	Lit	Not lit

5. Set the rotary switches for the node address to 01. The Unit mode change function will start, and the ERH indicator will flash for approximately five seconds.

Node address			Indicators
⋅ 161	⋅ 160	RUN	ERC	ERH
0	1	Flashing	Lit	Flashing

6. After the mode has been changed, the indicators will appear as shown be- low, depending on whether the change was completed normally or if an er- ror occurred.

• If the Mode Change was Completed Normally

Node address			Indicators
⋅ 161	⋅ 160	RUN	ERC	ERH
0	1	Flashing	Lit	Lit

• If an Error Occurred in the Mode Change

Node address			Indicators
⋅ 161	⋅ 160	RUN	ERC	ERH
0	1	Flashing	Lit	Not lit

Note If an error occurs in the mode change, remove the Ethernet Unit, create the I/O tables, and correct the settings using the procedures described in this section.
