If the interface module is operated as the first or last physical device as a 422, a bus termination
must also occur. By moving the "Rx 422 Termination" or " Tx 422 Termination
”
slide switch to
"On", the integrated terminators can be activated in the Rx or Tx direction.
DeviceNet Termination
If the interface module is located at the beginning or end of the data cable to the control panel,
there must be a bus termination at this gateway. To do this, set the "Termination" (DeviceNet)
sliding switch to "On". This activates the DeviceNet terminator (220
Ω
) built into the interface
module.
More information about bus termination can be found in the general fieldbus literature.

Operating modes
Configuration mode
The configuration mode is used to configure the WCS-DG310 interfaces. The following settings
are possible in this mode:
1. Install script
2. Update firmware
3. Configure the interface module
The interface module will start in this mode if the rotary switches S4 and S5 are both in position
"F." The interface module sends its switch-on message immediately after it has been switched
on in configuration mode. In configuration mode, the interface module always works with the
settings 9600 baud, no parity bit, 8 data bits, and 1 stop bit. The RS state LED always flashes
red, the "Error No/ Select ID" LEDs have no significance for the user. The configuration mode is
included in all software revisions.
Test mode
Setting test mode
Test mode is set by putting both switches S4 and S5 into position "E." No other switches are
considered when setting test mode. With these settings, the interface module must be
restarted (by disconnecting it briefly from the power supply). In test mode, the interface module
always works with the settings 9600 baud, no parity bit, 8 data bits, and 1 stop bit. Test mode
can be useful to get the interface module to integrate into the specific environment, e.g., in
order to test the parameters of the RS 485 interface.
Test mode functionality
After restarting in test mode, the gateway will send the values 0 - 15 in hexadecimal form
("0"..."F") in ASCII encoding to the serial side, in a 1-second rhythm. At the same time, the
same values are sent on the DeviceNet side in binary form. The state LED on the RS 485 side
will flash red in this mode, the "Error No/Select ID" LEDs will display the value currently being
sent in binary form. In addition, each character received on one of the interfaces is sent back
out on the same interface as a local echo. On the DeviceNet side, only the first byte is used for
the local echo, i.e., only the first byte of the bus data is checked both when receiving and
sending. The bus data does not change with respect to the previous data.
Note!
Rotary switch S4, rotary switch S5, DIP switch
For information on setting rotary switches S4 and S5 as well as the DIP switch, see see chapter
4.4.
