System Configuration
The following restrictions apply to PC Link Systems with CVM1-LK401 PC
Link Units.
1.
The CVM1-LK401 can communicate with C200H-LK401 Units as well as
C500-LK009-V1 Units in single-level LK009 mode or in a multi-level sys-
tem.
2.
3G2A5-LK009 and 3G2A5-LK003-E Units cannot be used. Also, C500-
LK009-V1 Units cannot be used in single-level LK003 mode.
When CVM1-LK401 PC Link Units will be used, the PC Link Units described
in restriction 2 above must be replaced or the Unit settings must be changed.
For details, refer to
SECTION 3 Replacing an Existing PC Link System
1-2-1
Single-level and Multi-level Systems
Single-level Systems
Up to 32 PLCs can be connected in a single-level system and up to 64 words
of data can be exchanged in the entire system.
• The following table shows the maximum number of PLCs that can be con-
nected for a given number of LR bits per PLC.
• The maximum number of PLCs that can be connected in the PC Link Sys-
tem is determined by the number of LR bits set per PLC. Only the Node 0
(polling node) setting is valid. The other nodes’ (polled node) settings are
disabled.
