Replacement Checklists
Section 3-6
Number of
LR Bits
Check setting on pins 6 to 8:
[
] Bits / [ ] Units
Set the same number of LR bits that
was set on the 3G2A5-LK009/C500-
LK009-V1.
Make the “number of LR bits”
setting on the polling node
(node 0) in the PC Link. The
“number of LR bits” settings
on the other nodes (polled
nodes) are ignored.
When a C500 PLC is replaced
with a CVM1/CV-series PLC,
the maximum number of Units
is double the original value for
the same number of LR bits,
because the LR Area is twice
as large.
In pattern B, the original
3G2A5-LK009/C500-LK009-
V1 is set to single-level LK003
mode.
Set the level/link number (next
item in table) to single-level
mode.
Note
:
Settings 011 to 111 are invalid
settings in the C500-LK009-
V1, but the number of LR bits
will be set to 64 bits/8 Units if
the setting is in the invalid
range.
