External '''[[Digital I/O]]''' can be managed by the program with a series of Non-Standard [[DMIS]] commands. 
These commands can be applied to I/O at controller level (when supported) or to an external I/O card (Verify on Arco control Panel for suitable cards). 

== Reading the value of an Input ==
These commands read the value of an input at the moment the command is executed. 

The sintax is : <code>INPUT_READ(input_number,card_name)</code> 

Where
::''input_number'': is the number of the input to be read 
::''card_name'': is the label of the additional card as described in Arco Control Panel. 
If the ''card_name'' value is not specified, then the input is read from the controller and not from the additional board. 

Example: 
<code>$$ read Input n° 5 from the controller </code>
::<code>DECL/BOOL,RSLT</code>
::<code>RSLT=ASSIGN/ INPUT_READ(5) </code>

<code>$$ read Input n° 5 from the external board with label ‘MyBoard’ set in the control panel.</code>
::<code>RSLT=ASSIGN/ INPUT_READ(5,’MyBoard’) </code>

===Important Note===
The command <code>IOTEST(n) </code> from version 3.6 has been obsoleted and it is no longer available. 

==Waiting a mask of input to be set==
This command waits until the mask of input is active, after that, the execution continues.

The sintax is : <code>CALL/EXTERN,DME,'logical_IO','wait_for_input_mask','card_name', input_number,value, input_number,value</code> 

Where 

::''card_name'': is the label of the additional card as described in Arco Control Panel. 
::''input_number'': is the number of the input to be read 
::''value'': is the expected value from the input (.true. or .false.) 

If the ''card_name'' value is not specified, then the input is read from the controller and not from the additional board. 

Example: 
<code>$$ wait until input 5 is true and 6 is false on the controller IO board</code>
::<code>CALL/EXTERN,DME,'logical_IO','wait_for_input_mask',5,.true.,6,.false.</code>

<code>$$ wait until input 5 is true and 6 is false on the external board called ‘myBoard’ in the control panel</code>
::<code>CALL/EXTERN,DME,'logical_IO','wait_for_input_mask',’myBoard’,5,.true.,6,.false.</code>

==Writing the value in an Output==
This command sets the value of an output. 
The sintax is : <code>CALL/EXTERN,DME,'logical_IO','output_set', 'card_name', input_number,value</code> 

Where 

::''card_name'': is the label of the additional card as described in Arco Control Panel. 
::''input_number'': is the number of the input to be read 
::''value'': is the value to be set (.true. or .false.) 

If the ''card_name value'' is not specified, then the input is read from the controller and not from the additional board. 

Example: 
<code>$$ set the output 5 to true on the controller IO board</code>
::<code>CALL/EXTERN,DME,'logical_IO', 'output_set',5,.true.</code>

<code>$$ set the output 5 to true on the external board called ‘myBoard’ in the control panel</code>
::<code>CALL/EXTERN,DME,'logical_IO', 'output_set',’myBoard’,5,.true.</code>

===Important Note===
The command:<code>IOSET,n</code> and <code>IORESET,n</code> from version 3.6 has been obsoleted and it is no longer available.
