Driving stepper motors driver with arduino and ethernet shield

The stepper are 8 in total driven by the 8 Dryver D1
The 8 motors are grouped into three subcategories:
Room1 (DryveD1 1-2-3)
Room2 (DryveD1 4-5)
Room3 (DryveD1 6-7-8)

We were thinking about driving the stepper via Binary mode:
putting high or low an output arduino pin enable/disables the movement
Room1 (DriverD1 1-2-3) going into one Arduino ArduinoRoom1
Room2 (DryveD1 4-5) going into one Arduino ArduinoRoom2
Room3 (DriverD1 6-7-8) going into one Arduino ArduinoRoom3

Each driver has 2 important input pins: START and STOP that goes into the Arduino.

So ArduinoRoom1 has pin A0-A1-A2 for START command of DriverD1 D2 D3
pin A3-A4-A5 for STOP command of Driver D1 D2 D3

ArduinoRoom2 has pin A0-A1 for START command of DriverD4 D5
pin A3-A4 for STOP command of Driver D4 D5

ArduinoRoom3 has pin A0-A1-A2 for START command of DriverD6 D7 D8
pin A3-A4-A5 for STOP command of Driver D6 D7 D8

The driver has also Ouput pins that shows the status of the driver: Active / Alert / Reference / Error. I would like to take those signals and report them in the webpage.

The webpage needs to have following features:

1. A clock taken from the PC and a day indication.
2. A settable windows time_for_start to send all together to all of the 8 drivers the start of the movement
A settable windows time_for_stop to send all together to all of the 8 drivers the stop of the movement
So I obtain a daily automation.
3. A toggle button to start and stop the start/stop of the single movement So I imagine a drawn square named ROOM1 in which there are three buttons indicating "START/STOP MOTOR1"
"START/STOP MOTOR2" "START/STOP MOTOR3" and so on.
4 Small leds that gets lid whenever an output is indicated.
