Product Description
2 Product Description
2.1 Use and Application
The WCS-ECG410 interface module acts as an interface between the WCS read head and the
EtherCAT controller. The device has two EtherCAT ports. Data is transferred between the WCS
read head or WCS read heads and the interface module via the RS-485 interface and from the
interface module to the controller via the EtherCAT protocol.
You can connect up to four LS221 or LS121 WCS read heads. f you connect several read
heads, they must have different addresses. The number of connected read heads is configured
in the hardware project planning.
The interface module supports the operation of read heads with the Extended option (WCS3B-
LS*E*), with distances of up to 629 meters.
2.2 Dimensions
The interface module housing has the following dimensions.

Power:
The "Power" LED lights up green: power supply is present.
State:
The "State" LED is green: Data is being exchanged with the WCS read heads. The four "Error
No/Select D" LEDs are used to display the number of the currently polled WCS read head.
The "State" LED lights up red: The interface module has detected an error or a warning. The
interface module displays the binary-coded error and/or warning number via the "Error
No/Select D" LEDs.

Error (No. 1...5): Switch the interface module off and back on. f the error occurs
again, the module must be replaced.
Warning (No. 6...15): The warning provides information. The interface module displays
the warning for one minute and then resets automatically.

Product Description
EtherCAT: LED Status Indicator
Bus State:
The states of the LEDs are defined as follows:
Bus Power:
The "Bus Power" LED is green: The LED is connected directly to the electrically isolated supply
voltage of the EtherCAT side.
Link/Activity In:
The "Link/Activity" LED at the N port is directly activated by the EtherCAT processing unit and
lights up green when the gateway at the RJ45( n) is located on an operational network (link
pulses are received) and flickers in case of network data traffic (activity).
Link/Activity Out:
The "Link/Activity" LED at the OUT port is directly activated by the EtherCAT processing unit
and lights up green when the gateway at the RJ45(Out) is located on an operational network
(link pulses are received) and flickers in case of network data traffic (activity).
ERR State (red LED) Error Description
Off No error The EtherCAT communication of the device
is ready for operation.
Flashing nvalid configuration General configuration error (example: wrong
object settings)
1 x flashing Unprompted status
change
The application changed the EtherCAT state
independently: The parameter "Change" in
the AL-status register is set to 0x01:
Change/Error
2 x flashing Application Watchdog
Timeout
The application has timed out (example:
10 ms R error)
RUN State (green LED) Status Description
Off N T The device is in the N T status.
Flashing PRE-OPERAT ONAL The device is in PRE-OPERAT ONAL
status.
1 x flashing SAFE OPERAT ONAL The device is in SAFE-OPERAT ONAL
status.
On OPERAT ONAL The device is in OPERAT ONAL status.
LED status Definition
On The LED is permanently on.
Off The LED is permanently off.
Flashing The LED changes the state from ON to OFF at a frequency of
2.5 Hz: ON for 200 ms, followed by OFF for 200 ms.
1 x flashing The LED lights up briefly (200 ms), followed by a long OFF phase
(1000 ms).
2 x flashing The LED shows a series of short flashes twice (200 ms), separated
by an OFF phase (200 ms). The series is completed with a long
OFF phase (1000 ms).
