Laser  State  Diagram will  remain  in BOOTING UP  state  and  the  ‘Booting  Up’  bit=1 (the 
‘Booting Up’ bit is bit 7 address 3 of the Input Assembly Memory Map). 
When  this  condition  is  achieved,  the  ‘Booting  Up’  bit  passes  1→0,  meaning  that  the 
LISTENING  state  has  been  reached.  Now  the  PLC  can  request  the  execution  of  a 
command to the Laser Marker.  
The execution of the command is underway when the 

Command Executing bit

 and the 

Mirroring Bit

 change state 0→1; moreover, as soon as the 

Command Executing bit

 and 

the 

Mirroring Bit

 change state 0→1, the PLC must reset the 

Command Bit

 1→0. If the 

selected 

Command Bit

 doesn’t have a matching 

Mirroring Bit

, then the 

Command Bit

 can 

be pulled down whenever 

Command Executing bit

 changes state 0→1. 

If,  by  any  chance,  the 

Command  Bit 

is  not  pulled  down  when  the 

Mirroring  Bit

  and 

Command Executing 

bit turns 0→1, then the 

Command Executing bit

 and the 

Mirroring 

Bit

  will  not  turn  to  0  when  the  command  is  ended.  The  Protocol  State  will  pass  in 

LISTENING as soon as the 

Command Executing bit

 passes 1→0. 

3.1.

 

Input Assembly Memory Map 

The input Assemby Memory Map has been developed in order to structure all the data 
coming  from  the  Datalogic  Laser  Marker  towards  the  PLC.  Depending  on  the 
information  that  the  Laser  is  returning  at  every  Update  Time,  the  PLC  could  need  to 
check a single bit or multiple bytes from the following memory map.
