The system disk for use with the A2C is SW4GP-GPPA.
If the SW3GP-GPPA system disk is used for booting, follow the instructions
On the A6PHP booted with the SW3GP-GPPA disk, set the CPU type as
The A2C has 8K steps of capacity for sequence programs and
By parameter setting, program capacity less than 8K steps should be .ill
' I II
Number of I/O points
The A2C has 512 input and output points from X/YO to X/y1FF.
Interrupt programs and interrupt counters are unusable.
On the A2C, interrupt programs (I to IRET) cannot be executed. Do not
set interrupt counters using parameters. Counters set for interrupt
counters cannot execute count processing with main routine programs
and subroutine programs.
Since the A2C does not execute interrupt programs, I (interrupt pointer)
is not usable.
The following instructions are not usable on the A2C.
(a) PR (ASCII print instruction)
(b) EI/D1 (Interrupt program allow/disallow)
(c) IRET (Interrupt program return)
Remote terminal setting
Remote terminal setting of the A2C is executed with the initial program
of the sequence program. (See Section 4.2.9 for details of the initial
