(PLC: A2U start-up)
• Because the PLC model names are different between in
writing and in reading, the following conditions are
identified.
1) If the verification is performed after reading, mismatch is
identified.
(The data can be used.)
2) Set values of the sampling trace/status latch (data stored
in the CPU module) will not be displayed.
3) When the network parameters are set to the new product,
they will not be displayed on the conventional product.

POINT
Do not read the A2USHCPU-S1/A2USCPU(S1)/A2ASCPU(S1/S30), to which the MELSECNET/10
network parameters were set by a new product, from a conventional product and perform the following
operation since a "LINK PARA. ERROR" (CPU module error) is detected.
(a) Modifying and writing in the main sequence program area (memory capacity).
(b) Writing the read parameters to another A2USHCPU-S1/A2USCPU(S1)/A2ASCPU(S1/S30) in the
network system.
