High-speed operation processing speed
Compared to the conventional A1SCPU, the A1SHCPU is three times and A2SHCPU
(S1) is four times faster in the operation processing speed, respectively.
Item
*1 I/O processing: Refresh and LD instruction
Addition of new dedicated instructions
The CC-Link dedicated instructions (8 instructions) have been added, making the
operation even easier.
Increased number of I/O device points
The actual number of I/O points is the same as the AnS series, but each CPU has
2048 points (X/Y0 to X/Y7FF) of I/O devices.
The added I/O device can be used as the MELSECNET (/B), MELSECNET/MINI-S3,
or CC-Link.
Increased file register R capacity
The capacity is now max. 8192 points (R0 to R8191), which doubled the AnS series'
4096 points (R0 to R4095).
Increased memory capacity (Increased number of comment points)
The A1SHCPU has 64 k bytes, which doubled the A1SCPU's 32 k bytes.
This increased the number of comment points stored in the CPU module 3648 points
in comparison to the 1600 points in A1SCPU.
Full compatibility with A1S(S1)/A2SCPU(S1)
Because there is full compatibility of the functions and instructions with A1S(S1)/
A2SCPU(S1), all software packages can be used.
In addition, power supply module, base unit, and I/O modules can be used.
Compact size
The appearance of the AnSHCPU system with one power supply module, one CPU,
and eight 16-point I/O modules for use with AnS mounted to the main base unit are:
430mm (16.9in.) (W); 130mm (5.12in.) (H); and 110mm (4.33in.) (D).
Max. 8 k/14 k steps of program
An A1SHCPU allows the creation of a sequence program up to 8k steps, an
A2SHCPU(S1) allows up to 14k steps.
In addition, microcomputer programs and utility programs created by the user can be
used.
