Network Configuration
34
configured network will have recurring communications errors, such as
remote I/O communications errors and transmission timeouts.
Total Branch Line Length
The total branch line length is the sum of the lengths of all branch lines in the
network. The maximum total branch line length depends upon the baud rate,
as shown in the following table.
Maximum Network Length
The maximum network length is the distance between the two nodes that are
farthest apart or the distance between the terminators, whichever is greater.
(The trunk line length and max. network length are not always the same.)
The maximum network length depends upon the baud rate and cable type, as
shown in the following table.
Maximum Current Capacity
The maximum current capacity of a line depends on the cable type and the
function of the line (trunk or branch line). When planning the network configu-
ration, consider the type of cable being used, position of each device, and
each device’s current consumption.
