APPENDIX
Appendix 3.2 Differences between A2SHCPU(S1) and A2SCPU
The differences between the A2SHCPU(S1) and A2SCPU are as follows:
*1 I/O processing: during refresh and LD instruction execution
*2 The number of the actual I/O points is the same as the AnS series, but this model has 2048
points of I/O device for each CPU (X/Y0 to X/Y7FF).The added I/O devices can be used for
MELSECNET (/B), MELSECNET/MINI, or CC-Link.
Appendix 3.3 Replacement precautions
Appendix 3.3.1 PLC type setting
The PLC type must be set to "A3" to enable the use of 2048 I/O device (X/Y) points, 8192
file register (R) points, and LEAD/LEDB instructions.
Appendix 3.3.2 Precautions when performing ROM partition
When performing ROM partition for A1SJHCPU(S8) or A1SHCPU with the SW4GP-
GPPA, the startup model must be changed as follows.
