Benefits of replacing the AnS/QnAS Series with the L Series

Increases the production capacity and shortens the operating cycle.
The L Series programmable controllers speed up the operation and processing speed (as fast as about 5 times the processing performance of the AnS Series) and the bus communication speed.
Upgrading the AnS/QnAS Series to the L Series significantly improves the production capacity.
Enables a flexible configuration without a base
The L Series does not need a base unit. Its installation footprint is minimum, which otherwise restricted by the size of the base unit. When adding modules, the number of slots on a base unit does not have to considered. The base-less architecture often eliminates the need of additional extension base units, saving the system cost.
Reduces the system cost by using built-in CPU functions
The LCPU module is equipped with a number of built-in functions such as the general input, interrupt input, pulse catch, general output, high speed counter, positioning, Ethernet and CC-Link communication functions.
Combining the built-in functions eliminates the needs of modules dedicated to each function, and such combined functions realize a variety of control functions while reducing the system cost.

L Series replacement example with the AnS/L upgrade tool products (conversion adapter, base adapter) and L Series space modules

(1)Remove the existing AnS/QnAS Series programmable controllers together with the base unit. Install the AnS/L base adapter.
(The existing installation holes can be used as they are. No additional holes need to be created.)
(2)Install a space module on the left side of the L Series module to which an AnS/L conversion adapter (terminal block type) will be attached.
(3)Attach the AnS/L conversion adapters to the L Series modules.
(4)Remove the wiring terminal block from the existing AnS/QnAS Series module and connect that wiring terminal block to the conversion adapter.

Nota 1: Use of the L Series space module may restrict the system configuration. Please refer to "MELSEC-L CPU Module User's Manual (Hardware Design, Maintenance and Inspection)" (SH-080890ENG) for the detailed specifications, cautionary notes and restrictions.
Note 2: Upgrading to the L Series module could result in a wider system width than the system width using the AnS/QnAS (small type). Please refer to "Transition from MELSEC-AnS/QnAS (Small Type) Series to L Series Handbook (Fundamentals)"(L(NA)08258ENG) for more details.

AnS/L upgrade tool products

The AnS/L upgrade tool products consists of two items-"conversion adapter" and "base adapter". The conversion adapter supports the conversion of the AnS/QnAS Series I/O and analog modules wiring to the corresponding L Series modules wiring. The base adapter is used to utilize the existing installation holes of the AnS/QnAS Series base units for the L Series programmable controller installation.

For utilizing the installation holes of the AnS/QnAS Series modules for the L Series installation.

Upgrading to the L Series module could result in a wider system width than the system width using the AnS/QnAS. If the width after upgrading is impractical, consider use of a DIN rail for installation.
Please refer to "Transition from MELSEC-AnS/QnAS (Small Type) Series to L Series Handbook (Fundamentals)" (L(NA)08258ENG) for more details.

Note 1:Use of the L Series space module may restrict the system configuration. Please refer to "MELSEC-L CPU Module User's Manual (Hardware Design, Maintenance and Inspection)" (SH-080890ENG) for the detailed specifications, precautions and restrictions.
