Bit-strobe
With bit-strobe access, the "Bit-strobe" command is sent from the master without any further
data. The master then always receives 8 data bytes from the interface module as a response.
The 8 data bytes contain the data of the WCS readers with the address 0 and 1 (2 x 4 bytes). If
the WCS reader with address 1 is not connected (rotary switch S4 is in position 1), the 4 data
bytes for this WCS reader are 0x00.
Change of state
In this method, the WCS-DG310 sends 8 data bytes to the master without request as soon as
the content of the data has changed. The data format corresponds to the data format for bit-
strobe access. If the WCS reader data changes constantly, e.g., if the reader is moving quickly,
the data is sent every 5 ms. In this case, the pause time is necessary to avoid overloading the
DeviceNet bus.

Interface module data format for one reader (4 byte)
Note!
For some control panels, the position of the bytes in a word are swapped. For a description of
the data bits, see chapter 5.4.
