Rotary switches
fig. 117
Set the address selector of the slave units to the required node address by
using the X1 (right) and X10 (left) rotary switches.
The setting range for the node address switches is 00 to 99.
When the rotary switches are set to 00, the node address will be assigned
automatically, depending on the position in the network.
The node address of digital and analog I/O slaves start from 1000.
The node address of the encoder input slaves start from 1.
To set the EtherCAT node address of the slave units, do these steps:
1. Turn off the Unit power supply of the slave units.
2. To set the address of the unit, either use auto-addressing by setting the
rotary switches to 00, or set the desired address with the rotary switches.
3. Turn the power on.

Note
The address of the slave units is read only at power on. Setting the
new address when the power is on has no effect.
Note
Make sure that the address is unique in the EtherCAT network. If
two or more IO units have the same node address, a configuration
error will occur.
Note
To make the EtherCAT address of the unit valid, do one of these
steps:
•
Restart the TJ2-MC__.
•
Execute the command
ETHERCAT(0,unit)
