Process images 

Definition of process image   

The process image is a component of the AS-i master system memory. 
At the start of the cyclic program, the signal states of the inputs are transferred to the 

process image for the inputs.  
At the end of the cyclic program, the process image of the output is transferred to the slave 

as a signal state. 

Input process image (PII)   

The following table contains process data and a process image for inputs DI 0 to DI 3: 

 

Byte / bit  Process image  

Signal: 1 = HIGH, 0 = LOW 

DI 0 

Ready (automatic) 

0: Starter not ready for host / PLC 

1: Starter ready to be operated via host 

DI 1 

Motor ON 

0: OFF 

1: ON (CW / CCW) 

DI 2 

Input 1  

(input action: quick stop) 

0: Not active 

1: Active 

DI 3 

Input 2  

(no action) 

0: Not active 

1: Active 

Output process image (PIO)   

The following table contains process data and a process image for outputs DO 0 to DO 3: 

 

Byte / bit  Process image  

Signal: 1 = HIGH, 0 = LOW 

DO 0 

Motor RIGHT 

0: Motor OFF 

1: Motor ON 

DO 1 

Motor CCW 

0: Motor OFF 

1: Motor ON
