Rotary switches
Set the address selector of the GRT1-ECT 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, starting from 1000.
When set from 01 to 99, the node address assigned will 1000 plus the switch
setting.
To set the EtherCAT node address of the GRT1-ECT, do these steps:
1. Turn off the Unit power supply of the GRT1-ECT.
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 GRT1-ECT 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)
