Replacement Checklists
Section 3-6
Checklist 4
Use the following checklist when replacing a 3G2A5-LK003-E with a CVM1-
LK401.
Item
Original Unit: 3G2A5-LK003-E
Replacement Unit: CVM1-LK401
Remarks
CPU Bus Unit
unit number
Not applicable
Any unique number in setting range
(Do not set the same unit number on
two CPU Bus Units in a PLC.)
Do not mount more PC Link
Units than allowed.
Node
address
Check pins 1 to 5: [ ]
Set the CVM1-LK401’s node address
to the same node address that was set
on the 3G2A5-LK003-E. (Set the rotary
switches in 2-digit decimal in the range
00 to 07.)
The setting range for the
3G2A5-LK003-E’s node
address is 0 to 7.
Check the node address set-
tings on other nodes in the PC
Link to confirm that the same
address is not already taken.
A Unit error will
not
occur if
the same node address is set
on two PC Link Units in the
same PC Link, but there will
be data errors in the LR Area.

Pins 1 and 2 of the front-panel
switch are not used and do not
affect the node address setting.
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-LK003-E.
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.
Set the level/link number (next
item in table) to single-level
mode.

Level/Link
Number
Not applicable.
Pins 3 and 4: Set both pins to 1 (single-
level).
The 3G2A5-LK003-E supports
only single-level LK003 mode.
Set the replacement CVM1-
LK401 to single-level mode.

WIRE switch: Set to 2 (right).
The 3G2A5-LK003-E does not
support optical fiber cable; it
supports only electrical
cables.

TER switch: Set the same setting as
set on the 3G2A5-LK003-E.
