Product description
2 Product description
2.1 Use and application
The WCS-ECG110 interface module serves as an interface between the WCS reader and the
EtherCAT controller. The device has 2 EtherCAT ports. The data is transferred between the
WCS reader(s) and the WCS-ECG310 via the RS-485 interface, and from the WCS-ECG310
to the control panel via the EtherCAT protocol.
You can connect up to 4 WCS readers of type LS221 or LS121. If you connect several readers,
they must have different addresses. The number of connected readers is configured in the
hardware project settings.
2.2 Dimensions
The interface module housing has the following dimensions.

Power:
The "Power" LED is green: The WCS-ECG110 interface module is correctly connected to the
power supply.
State:
The "State" LED is green: Data is being exchanged with the WCS readers. Using the 4 "Error
No/Select ID" LEDS, the number of the currently polled WCS reader is displayed.
The "State" LED is 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 ID"
LEDs.

Error no. 1...5: Switch the interface module off and back on. If 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
The states of the LEDs are defined as follows:
EtherCAT Power:
The "EtherCAT" LED is green: The LED is connected directly to the electrically isolated supply
voltage of the PROFINET side.
EtherCAT Link/Activity In:
The "Link/Activity" LED at the IN port is directly activated by the EtherCAT processing unit and
lights up green when the gateway at the RJ45(In) is located on an operational network (link
pulses are received) and flickers in case of network data traffic (activity).
EtherCAT 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).
RUN State (green
LED)Status Description
Off INIT The device is in the INIT status.
flashing PRE-OPERATIONAL The device is in PRE-OPERATIONAL
status.
1 x flashing SAFE OPERATIONAL The device is in the SAFE-
OPERATIONAL status.
on OPERATIONAL The device is in OPERATIONAL 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).
