INTRODUCTION
Replacement procedures:
(1) Remove the existing AnS series modules together with the base unit, and use the
existing mounting holes to mount the upgrade tool (Base adapter) manufactured by
Mitsubishi Electric Engineering Co., Ltd. Then mount the Q series. (By mounting the
base adapter, it is not necessary to redo the mounting holes.)
If the existing base unit is mounted on a DIN rail, the replaced Q series base unit can be
directed installed, so a base adaptor is unnecessary.
(2) Mount the upgrade tool (Conversion adapter) manufactured by Mitsubishi Electric
Engineering Co., Ltd. on the mounted Q series I/O modules.
(3) Remove the terminal blocks wired from the existing AnS series I/O modules, and mount
the blocks on the conversion adapter. (The existing wiring is usable.)
(4) Programs are automatically converted* by changing the programmable controller type
from AnS/QnASCPU to QCPU using GX Developer.
Even if the module arrangement is changed, the I/O can be assigned to the same
number as before, which cuts out the need to modify the programs and slot number for
I/O module.
* Some instructions are not automatically converted. In case of intelligent function module or network module, programs and
parameters need be changed.
Existing AnS Series
When replacing the AnS Series I/O module with the Q
Series I/O module, the FA goods conversion module
and interface terminal module can also be used.
