Commissioning and configuration
12.1
Measures to be performed prior to the initial commissioning
Before commissioning, familiarize yourself with the operation and configuration of the
MA 255
i
.
Before connecting the supply voltage
,
recheck all connections and ensure that they
have been properly made.
The Leuze device must be connected to the internal RS 232 device interface.
Connecting the Leuze device
Open the housing of the MA 255
i
and guide the corresponding device cable (e.g., KB 031
for BCL 32) through the middle threaded opening.
Connect the cable to the internal device interface (X30, X31 or X32,
see chapter 7.5.1
Use rotary switch S4 (see chapter 8.2.5) to select the connected device.
Now screw the PG cable gland into the threaded opening to provide strain relief and
ensure protection class IP 65.
Set DeviceNet device address
By setting the DeviceNet address, the MA 255
i
is assigned its respective station number.
Each network device is thereby automatically informed that it is a slave on the DeviceNet
with its specific address and that it is initialized and queried by the PLC.
The DeviceNet permits an address range from 0 to 63. Other addresses must not be used
for data communication.
Set the station address of the gateway using the two rotary switches
S1
and
S2
(ones
and tens places).
