Specifications and Configurations
Section 1-2
Functions Supported by CS/CJ-series Controller Link Units
Note
1.
A maximum of 32 nodes can be set without using a Repeater Unit (CS1W-
RPT0
@
).
2.
A network can contain both new and old models. In that case, the system
must be configured using the specifications for the old models. The num-
ber of data link send and receive words, however, can be set separately for
old and new models with up to the maximum number of words set for each.
Use the CX-Net in CX-Programmer version 5.0 or higher to set a data link
area in which the number of send and receive words exceeds 12,000 words.
CX-Integrator version 3.2 or higher can be used to change data link alloca-
tions while manually set data links are active.
Up to eight CS/CJ-series Controller Link Units with unit version 1.2 or later
can be connected to a single CPU Unit. When connecting multiple Controller
Link Units to the CPU Unit, consider the current consumption of the CPU Unit
and each CPU Bus Unit before selecting the Power Supply Unit. For details on
Controller Link Unit current consumption, refer to
on page 18. For details on current consumption of each Unit, refer
to the operation manual of the PLC that is being used.
The following table provides an example of current consumption.
Example: Using the C200HW-PA204 Power Supply Unit supplying a maxi-
mum current of 4.6 A (5 V) and maximum power of 30 W.
