編輯數字I / O
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).

[隱藏]Reading the value of an Input
These commands read the value of an input at the moment the command is executed.
The sintax is : INPUT_READ(input_number,card_name)
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.
- input_number: is the number of the input to be read
If the card_name value is not specified, then the input is read from the controller and not from the additional board.
Example:
$$ read Input n° 5 from the controller
DECL/BOOL,RSLTRSLT=ASSIGN/ INPUT_READ(5)
$$ read Input n° 5 from the external board with label ‘MyBoard’ set in the control panel.
RSLT=ASSIGN/ INPUT_READ(5,’MyBoard’)
Important Note
The command IOTEST(n) 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 : CALL/EXTERN,DME,'logical_IO','wait_for_input_mask','card_name', input_number,value, input_number,value
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.)
- 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:
$$ wait until input 5 is true and 6 is false on the controller IO board
CALL/EXTERN,DME,'logical_IO','wait_for_input_mask',5,.true.,6,.false.
$$ wait until input 5 is true and 6 is false on the external board called ‘myBoard’ in the control panel
CALL/EXTERN,DME,'logical_IO','wait_for_input_mask',’myBoard’,5,.true.,6,.false.
Writing the value in an Output
This command sets the value of an output.
The sintax is : CALL/EXTERN,DME,'logical_IO','output_set', 'card_name', input_number,value
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.)
- 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:
$$ set the output 5 to true on the controller IO board
CALL/EXTERN,DME,'logical_IO', 'output_set',5,.true.
$$ set the output 5 to true on the external board called ‘myBoard’ in the control panel
CALL/EXTERN,DME,'logical_IO', 'output_set',’myBoard’,5,.true.
Important Note
The command:IOSET,n and IORESET,n from version 3.6 has been obsoleted and it is no longer available.
