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

| |
| − | == Reading the value of an Input ==
| |
| − | These commands read the value of an input at the moment the command is executed.<br/>
| |
| − |
| |
| − | The sintax is : <code>INPUT_READ(input_number,card_name)</code><br>
| |
| − |
| |
| − | Where
| |
| − | ::''input_number'': is the number of the input to be read<br/>
| |
| − | ::''card_name'': is the label of the additional card as described in Arco Control Panel.<br/>
| |
| − | If the ''card_name'' value is not specified, then the input is read from the controller and not from the additional board.<br/>
| |

| |
| − | Example:<br/>

| − | <code><span style="color: green; text-decoration: none;">$$ read Input n° 5 from the controller </span></code>

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

| − | ==Writing the value in an Output==
