(2) Switch
With this switch, the operation of the Ethernet adapter module can be controlled.
*1 Even if the switch is set to "STOP", the Ethernet adapter module is shown to be in the cyclic transmission status at the
master station.
Name Description
RESET/TEST
The Ethernet adapter module can be reset by the following method.
Set the switch with your fingertip. Using a tool such as a screwdriver may damage the switch.
You can also switch the Ethernet adapter module to the test mode and reset the parameters to default values.
For switching to the test mode, refer to "Testing the Module Before Wiring." ( Page 57, Section 6.3)
For resetting the parameters to default values, refer to "Resetting Parameters to Factory Default Values."
( Page 222, Appendix 6)
STOP
*1
Transfer between the link devices (cyclic data from the master station) and the devices of the Ethernet adapter
module is stopped. (Transfer is stopped while cyclic transmission with the master station is continued.)
This transfer stop can prevent the data exchanged between an external device and the Ethernet adapter module
from being sent to the master and local stations. The STOP switch is used for a purpose, such as debugging
between the Ethernet adapter module and external devices.
Debugging communication data with an external device using the STOP switch
(1) Set the switch to "STOP."
(2) Data transfer between the link devices and devices of the Ethernet adapter module is stopped, and the
Ethernet adapter module is separated from the master station control.
(3) Check if communications are normally performed between the Ethernet adapter module and an external
device. Because transfer is stopped, data exchanged between the Ethernet adapter module and the external
device will not be sent to the master and local stations.
(4) After checking the above, write the parameters to the Ethernet adapter module and start the system
operation.
RUN
Cyclic transmission starts between the Ethernet adapter module and the master station. (Data communication
between the Ethernet adapter module and external devices is performed regardless of the switch status.)
1. Shift the switch to RESET/TEST for one
second or longer.
Hold the switch and do not release it.
2. Confirm that the ERR. LED flashes
several times and then turns off.
3. Set the switch back to the STOP
position.
The switch will automatically return to the
STOP position when released.
