System Configuration
Section 1-2
• The following example shows the structure of a single-level system set to
transfer 256 LR bits/PLC in 4 PLCs.
Multi-level Systems
(4 Levels Max.)
Like the 3G2A5-LK009 and C200H-LK401 PC Link Units, two CVM1-LK401
PC Link Units can be mounted in a single PLC to create a multi-level system.
An operating level in a multi-level system can support one-half as many Link
Relay bits (32 words total) as the operating level in a single-level system. For
details, refer to
Up to 4 operating levels can be configured in a PC Link System.
