Set baud rate (DIP switch)
You can set the baud rate in DeviceNet with 2 switches on the 8-way DIP switch of the WCS-
DG310. The location of the DIP switches is marked on the device label.

Connection to the Control Panel
Connect the WCS-DG310 interface module to DeviceNet via the 5-pin connector with X3
screw terminals.
Set the setting ID of the DeviceNet address via the 8-way DIP-switch "Node ID". MAC ID "0" is
not allowed.
You can switch the terminator in the DeviceNet bus on and off via the "Termination" sliding
switch.

Data Exchange in DeviceNet
In DeviceNet, the DG310 works as a "Group 2 Only Slave". The access methods "polling", "bit-
strobe", and "change of state" are supported. If you connect more than 2 WCS readers to the
WCS-DG310, you can only query the data from the master via polling access. The sending of a
function byte is likewise only possible in polling mode.
Polling
In polling, a function byte is sent from the master to the WCS-DG310. The WCS-DG310 returns
16 data bytes. The 16 bytes contain the data of the four WCS readers (4 x 4 bytes). If fewer than
4 WCS readers are configured (via rotary switch S4), the 4 data bytes for the WCS readers not
configured contain the value 0x00.
