Simulation Debugging



Simulation Debugging

You can debug your HMI project at any time, even without the STONE Display. The command input area allows you to send any STONE command to check the system feedback and HMI interaction.



ASCII-based control logic
and instruction set

Simple ASCII text-based commands will greatly reduce your HMI project development effort.

Set text:
ST<{“cmd_code”: “set_text”, “type”: “label”, “widget”: “label1”, “text”: “Hello STONE”}>ET
Get the text:
ST<{“cmd_code”: “get_text”, “type”: “mledit”, “widget”: “mledit”}>ET
“set_text” represents the command function code
“type”: “label” means the type of the control is label
“widget”:” label1″ means the actual name of the control is label1
“text”:” Hello STONE” means that the text is Hello STONE
