CAN Internet:
The transmission rate set for all hosts in the network must be the same, the networked
hosts must be acknowledged and the host number shall differ from each other. The Network
setup interface is as follows:
Figure 4-7 Network setup interface with CAN
After modification of Network setup information, the machine
can operate normally only after power-on again.
Modifying method: select address of the host in drop-down box of "Host number", click the "Info
Share" and the left blank box will display "
√
", select "CAN " in the Network Md options,then click
on drop-down box of "CAN transmission rate" and select the transmission rate of networking bus,
and finally click on the corresponding "Register" column on the networked hosts to display "
√
".
Then press OK button to save the setup and exit, otherwise press Cancel button to retain the
original setup and exit.
The transmission rate set for all hosts in the networking system must be
the same! After setup of the networking transmission rate, the host must be restarted
to take effect!
If the host under different rates is connected into the network,
no hosts (including other hosts with the same transmission rate) will provide normal
communications. Therefore, for the networking system with multiple hosts, the
networking bus will not operate normally during the process of setting transmission
rate for the hosts one by one and the system networking returns to the normal
condition after the same transmission rates have been set for all hosts.
Selection of networking transmission rate.
10K, 20K, 50K and 100K can be selected as the networking transmission rate. The rate is
not the faster, the better and shall be selected based on the following situations:
Number of networked hosts
Length of networked bus (distance between hosts)
Type of networking transmission line
Number of networked hosts
The greater the number of networked hosts, the larger the volume of transmitted data on
the bus. Therefore, if the networked hosts are large in number (generally greater than 5), it is
suggested to use a higher communication rate, such as 100K.
Length of networked bus
The higher the transmission rate, the smaller the maximum transmission distance of the
bus. The lower the transmission rate, the better the transmission interference immunity of the
