1.1 Advantages of Transition to L Series

Advantage 1) Advanced performance of equipments (shortened takt time)
In addition to the processing performance improvement for L series CPU, the processing
speed for L series intelligent function module is also increased, so that the equipment
capability to improve is possible.
Advantage 2) Baseless, flexible composition
The L series does not require a main base unit and can be installed in a minimum space
without restrictions of the base unit size.
Even when a module is added, the number of modules is not constrained by the number of
base slots, therefore the system cost such as addition of an extension base unit can be
suppressed.
Advantage 3) Improved operating efficiency for programming and monitoring
The intelligent function module operation of GX Works2 can be used on the L series
intelligent function module.
Though using the intelligent function module operation of GX Works2 is not required, the
use enables the following and can reduce sequence programs.
• Initial setting is possible without a program.
• The auto refresh setting allows to read/write buffer memory data of intelligent function
module automatically from/to the CPU device memory.
• Checking of the setting status or operating status of intelligent function module is
simplified.

1.2 Precautions for Transition

(1) When replacing the AnS/QnAS series with the L series, be sure to read the manuals of each L
series module and confirm the functions, specifications, and how to use before using the L
series.
(2) After the AnS/QnAS series is replaced with the L series, be sure to verify the operation of the
entire system before the start of operations.
