7.3 Precautions for Replacement of Parameter

7.3.1 Conversion from AnSCPU to QCPU

This section explains the parameter conversion upon replacement of the AnSCPU programs with the
QCPU.
<Compatibility>
: Common item between AnSCPU and QCPU, that can be converted directly.
: Item that requires re-setting after the conversion, since the functions/specifications are partially
different
: Item to be deleted, since there is no common item between the AnSCPU and QCPU.
Confirm the parameters after the conversion, and correct/re-set as required.

No need to care about the program capacity.

No microcomputer program is available.
Not required, since comments can be created for all devices.
Resetting is required since the specifications are different.
This becomes default (200ms).
This becomes default (All stop).

No compatible function is available.
Re-setting is required.
This becomes default (Output before STOP).
Use COM instructions, or set the service processing setting in the PLC parameter.
Re-setting is required.
Reviewing is required for the base unit with other than 8 slots.
 This resets to default.
M and L are different devices.

"L" on the program is converted to "L".


Converted as one device.
Reviewing is required, since all the range from lowest device No. to highest device No. is
included in the latch range.
Converted as one device.
Reviewing is required, since all range from lowest device No. to highest device No. is
included in the latch range.
Converted as one device.
Reviewing is required, since the latch range covers all range from lowest device No. to
highest device No.
Parameters are deleted, since the Q series CPU is not compatible with the MELSECNET

(II), /B.
For A2USCPU, converted to the MELSCECNET/10 mode.

Parameter re-setting is required for the AnS(H)CPU.

Parameters are deleted, since the QCPU is not compatible with the MELSECNET/MINI.
