A python based HMI system. You can define your devices in the config/drivers.json file and then read/write from each device with the /read/driver/tag and /write/driver/tag apis.
Screens are jinja hmtl templates were elements with specific classes set get turned into HMI elements.
the autoload_value class signals the system to read the data-target property and update the value property if it has one, otherwise it will replace the innerhtml.
Here is an example of a multistate indicator like you'd find in other packages:
<select class="autoload_value multistate_indicator" data-target="plc/Program:Smoker.state" value="false">
<option value="0">Off</option>
<option value="10">Purge</option>
<option value="20">Ignite</option>
<option value="30">Ramp Up</option>
<option value="40">PID Hold</option>
<option value="50">Ramp Down</option>
<option value="100">Shutdown</option>
</select>
Here's a data input box. Inputs with the autooad_value class will automatically write to their data-target when updated.
<span class="label">Burner SP</span>
<input class="autoload_value" data-target="plc/Program:Smoker.temp_sp", value=0>
Here's a button. Buttons use the special classes pb_momentary and pb_toggle with data-press and data-release properties.:
<button class="pb_toggle" data-target="plc/Program:Smoker.enable_autostart" data-press="1" data-release="0">Autostart</button>
New drivers can be added to the drivers directory. The CIP driver uses pylogix to communicate to allen bradley PLCs. There is also a modbus driver but I don't remember if I ever tested it so it might or might not work. There is also a "driver" that will execute simple ladder logic and there is a driver for "internal" hmi tags.
