APPENDIX
Appendix4.4 I/O control method
The I/O control method of the A2USHCPU-S1,A2USCPU(S1) and A2ASCPU(S1/S30)
is the refresh method (partial direct I/O depending on the instruction), and is different from
that of the A1SHCPU and A2SHCPU. Therefore pay attention to the input timing of the
input (X) and the output timing of the output (Y).
(1) Pulse processing program by the SET/RST instruction
To make the A2USHCPU-S1, A2USCPU(S1) and A2ASCPU(S1/S30) execute the
pulse output used in the direct method by the SET/RST instruction in the A1SHCPU
or A2SHCPU, create the program as follows:
For direct method of the A1SHCPU and
A2SHCPU
(a) When the ACPU common
instructions are used:
For A2USHCPU-
S1,A2USCPU(S1),A2ASCPU(S1/S30)
(b) When the dedicated instructions
for the A2USHCPU-S1,
A2USCPU(S1) or A2ASCPU(S1/
S30) are used:
POINT
When a special function module such as the AD61(S1) high-speed counter
module is used, use the above program if outputting the pulse signals to the
module is required.
