Note A network can contain both nodes with maximum of 20,000 data link words and nodes with 12,000 data link words. When models with -V1 suffix and those without -V1 suffix are both used in the same network, 1:N automatic data links and configurations of 62 nodes cannot be used.

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-Programmer 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 Controller Link Unit Models

and PLCs on page 16. 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.
