Programming an ASi Slave 
(Operand Syntax)

Programming digital input and outputs for ASi slaves is 
very similar to programming Suconet K devices. 
However, special operand parameters are required for 
the ASi interface.

One byte is provided for each ASi device in the input 
and output process image of the PLC to store the 
input and output states. Your program can scan or 
set single bits or the entire byte. 

I

L. A. M. B. X

Addressing an input bit

Q

L. A. M. B. X

Addressing an output bit

or

IB

L. A. M. B

Addressing an input byte

QB L. A. M. B

Addressing an output byte

Bit number (0 to 3)
Byte number (ASi: always 0)
Module number (ASi: always 0)
Address (1 to 31)
Line number (ASi: 2 or 3)
