Need an HMI program in python that communicates with a Delta ES2 PLC

Create an HMI program, using python, that runs on a PC and communicates with a Delta ES2 PLC HMI Features Needed a. Description and function i. Place buttons, boxes on a tkinker canvas ii. Develop (on/off) functions that connects each button to a M – (defined at creation) memory address. The function of the button, on or off sets the value of the M address in the PLC iii. Develop (input) functions that connects each input box to a D (defined at creation) memory address. When the button is clicked, is asks for a value, it is displayed and applied to the D address in the PLC 2. Button types needed a. Momentary push button i. This style of button sets a boolean M address value while the button is pressed (on). Once the user releases the button, the value goes back to zero (off) b. Maintained/latching push button - Similar to the momentary push button, except the M address value will be set until the button is reset (pressed again) 3. Input and Display Boxes needed a. Input i. Text and numeric inputs – 1. When the boxes are created they are connected to a function that connects them to a (defined at creation) D address in the PLC 2. When the box is clicked, it asks for a value that is then applied to the D value for its memory address. The value would be displayed in the box. 3. May need separate function for Text input and numeric input, I am not sure. b. The communication between the PC program and the PLC is by a RS-232 connection. i. This connection would be built using the pySerial add in I think. ii. The command format required by the PLC is the Modbus Protocol, attached.
