APPENDICES
(2) The compatibility of the conventional products (The existing system products) and
the new products (The AnU-compatible products) are listed in the following table.
No.
Product Used to Write to the
CPU Module
Product Used to Read from
the CPU module
Compatibility
1
The conventional product
(Programmable controller:
A3A start-up)
New product
(Programmable controller:
A3A start-up)
• All the data are compatible.
2
New product
(Programmable controller:
A3A start-up)
The conventional product
(Programmable controller:
A3A start-up)
3
The conventional product
(Programmable controller:
A3A start-up)
New product
(Programmable controller:
A3U start-up)
• Because the programmable controller model names are
different between when writing and when reading, the
following conditions are identified.
1) If the verification is performed after reading, it turned out
to be a mismatch.
(The data can be used.)
2) The setting values of the sampling trace/status latch
(data stored in the CPU module) cannot be displayed.
3) When the network parameters are set to the new product,
they cannot be displayed on the conventional product.
4
New product
(Programmable controller:
A3U start-up)
The conventional product
(Programmable controller:
A3A start-up)
POINT
Do not read the QCPU-A, to which the MELSECNET/10 network parameters were
set using a new product, from the conventional product and do not perform the
following operation since the "LINK PARA. ERROR" (CPU module error) is
detected.
(a) Modifying and writing the main sequence program area (Memory capacity).
(b) Writing the read parameters to another QCPU-A in the network system.
