Electrical connection
7.4.4
The BCL 501
The BCL 501
transmit data to the multiNet master only after the master prompts it to do so and establish
the continuing connection via the BUS OUT socket to the slaves which follow. Only a few
parameters need to be set for slave operation (see chapter 10 "Commissioning and config-
uration"). Network commissioning can thus be performed in very little time.
The connection is performed as shown in figure 7.8.
Slave address
With the BCL 501
number of the slave. The address which is set must be > 0 since the master always has
address 0 (Adr.00).
Each network device with an address > 0 is thereby automatically informed that it is a slave
in the Leuze multiNet plus with this address and that it is initialised and queried by the
network master. No other settings are necessary for commissioning in the Leuze
multiNet plus.
Other settings
The parameters necessary for the reading task, such as the code types to be read and the
number of digits of the code, must be set. This can be performed via the display as well as
with the aid of the webConfig tool.
