CPU MODULE 4.
(b) When the main program is made into E
2
PROM
Even when making the main program into E
2
PROM, the extension file register
cannot be enlarged, because the built-in RAM area (area shown in the following
figure
*1
) will be used in the system.(Applicable memory cassette A2SNMCA-
30KE)
1) For A2USHCPU-S1, A2ASCPU-S30
2) For A2USCPU(S1), A2ASCPU, A2ASCPU-S1
* If the MELSECNET(II) data link system is configured using a GPP function software package
for the AnU, 2k bytes (for 1k step) are occupied as a link parameter area.
