2. SYSTEM CONFIGURATION
For A2USHCPU-S1, A2ASCPU-S30 use caution on the followings.
NOTE
(a) Since the PLC's model name for the GPP function software package (SW IVD-
GPPA; is older than 3 is set to "A3U", pay attention to the followings:
1) When the LED or LEDC instruction is written, it is not usable but no error will
be issued.
2) When the CHG instruction is written, it is not usable, and the error code 13
and detailed error code 134 will be detected.
3) When the subprogram is set, it is not usable, and the error code 11 and
detailed error code 111 will be detected.
(b) When the MELSECNET(II), MELSECNET/10 parameters are used up to the
maximum of 16k bytes, program capacity will be limited to 22k steps.
The A2USHCPU-S1 uses the same memory area for the sequence program as
that for the parameters of MELSECNET(II) and MELSECNET/10.
Therefore, the remainder which is subtracted the memory area used by the
MELSECNET(II) and MELSECNET/10 parameters from the max. 30k steps can
be used for the sequence program.
POINT
(1) Old software packages other than SW3-GPPA, SW3GP-GPPA, and SW4GP-
GPPA cannot be used as the software package for system start-up for
A6GPP/A6PHP.
(2) When the MELSECNET/10 network system is configured with the
A2USHCPU-S1 or A2ASCPU-S30, use the AnU/A2USH-S1/A2AS-S30
compatible GPP function software package (which contains "A3U" / "A2USH-
S1" in the PLC's model name).
The network function cannot be set with GPP function software packages not
compatible with AnU, A2USH-S1 or A2AS-S30 (no "A3U", "A2USH-S1" or
"A2AS-S30" in the PLC's model name).
