Configuring the Rotary Encoding Switch
Each bus coupler automatically receives an EtherCAT device identification address. Use the
rotary encoding switch to configure the address manually.
The S1 switch sets the tens digit and the S2 switch sets the ones digit. The code results from
the equation (S1 x 10) + S2.
The following figure shows code 77 (7 x 10 + 7).

After setting the rotary switches, restart the REM-11180 to update the address assignment.
Note NI EtherCAT master does not support the rotary encoding switch on the
REM-11180.
Restoring Default Settings
To restore the REM-11180 to default settings, follow these steps:
1. Disconnect power to the REM-11180.
2. Press and hold the reset button.
3. Power on the REM-11180.
4. Release the button when the RDY LED flashes red and green.
Reading Error Codes from REM-11180 IOVs
When you add the REM-11180 to the RT Target in the LabVIEW project, the following IOVs
are available:
Table 6. LabVIEW Project IOVs for Remote I/O Systems
IOV Data Type Purpose
Localbus Add_Error
Info U16 Indicates which I/O module is returning an error.
Localbus bus State U16 Returns the current bus state. Refer to the Diagnostic
Status Register table for more information.
REM-11180 User Manual | © National Instruments | 9
Table 6. LabVIEW Project IOVs for Remote I/O Systems (Continued)
IOV Data Type Purpose
Localbus Error_Code U16 Returns error codes for the I/O module. Refer to the
I/O Module Error Codes table for more information.
Newest Diagnosis
Message U16
Returns the new message available bit (Index 10F3hex
sub-index 04). Refer to the Diagnosis History Object
table for more information.
Diagnostics
Diagnosis History Object
The diagnosis history object (10F3hex) implements as a ring memory in Overwrite mode. The
last 16 diagnostic messages are always stored. Older messages are deleted. Bus coupler and
I/O errors are stored in the object's diagnostic messages.
