7.8.2 The BCL 600i as network master
Master operation
The BCL 600i bar code readers are specially designed for master operation in a network. They manage
the data of the slaves in multiNet plus and establish the connection to the superior host computer. Only a
few parameters need to be set for master operation. Network commissioning can thus be performed in
very little time (see chapter 10 "Starting up the device - Configuration").
Last slave address
Unlike the slaves, the display of the BCL 600i is not used to set the network address (the master always
has the address 00), but the last slave address, i.e. the number of the most significant slave. This “informs”
the BCL 600i master of the number of slaves operating on the network, without requiring you to call up the
webConfig tool. If the network is expanded at a later time, you only need to change the number of slaves
(last slave address) accordingly via the display.
Start-up / timeout messages
During the initialization phase, i.e. after switching on the operating voltage, the master searches for the set
number of slaves. If a slave is found, the master generates a start-up message “S” for the respective
address found, e.g. “04S” -> Slave with the address 04 has responded correctly.
If a slave is not found or does not respond, the master generates a “timeout” (response timeout) at this
address.
The slave address and a “T” are output on the host interface. For example, “08T” means that no slave
responded at the network address 08. The network is still operational with one or several reported
“timeouts”, however, a slave, for which a timeout was generated, can no longer be addressed.
BCL 600i master mounting location
Ensure that the BCL 600i is mounted in an easily accessible and visible place in your system. Once the
network has been put into operation, you can set (configure) every scanner in the network centrally via the
USB service or host interface of the BCL 600i, without having to connect a PC/terminal to the individual
read stations.
7.8.3 The BCL 600i as network slave
Alternatively, the bar code readers of the BCL 600i series can also operate as slave participants in the
network mode. They now transmit data to the multiNet master (e.g. BCL 600i) only after the master
prompts them to do so, and, using an external M 12 T-connector, they establish the continuing connection
via the BUS OUT socket to the slaves which follow (order information see chapter 16.3 "Accessories").
The last network participant must be terminated with a terminating resistor.
Use the recommended connectors / sockets or the ready-made cables and terminating resistors
