PiDiCNC

PiDiCNC system is designed to connect the Raspberry Pi 2, using the application in the CNC or PLC.
The system allows to combine the modules as necessary.
The system does not require any computer. Raspberry PI 2 fully replaces it. It can be connected to it
classic monitor, keyboard and mouse, or LCD display.
Running under Linux OS. PiDiCNC is fully managed with LinuxCNC. PiDiPLC can be controlled by CODESYS program.
Now we have modules 3805, 3806 (extended module 3805) and 3809.

3805/6 module is aimed at the CNC allows a stepper motor control.
It contains everything you need to manage less complex CNC machines (eg. CNC milling).
A greater number of engines can be achieved by adding the appropriate number of modules 3805/6.
Components:
4 x stepper motors with a current of approx. 1.5A (max. 2.5A). Microstepping 6400 pulses / revolution.
      Instead of internal converters can use external drives with the required interventions such as STEP-DIR.
5 x digital input 0-24V
3 x digital outputs - open collector 0-24V / 2.5A
1 x relay output 230V / 5A
7 x binary output - open collector 0-24V / 0.2A
1 x analog output 0-10V.
The binary outputs (7 x open collector 0-24V / 0.2A), it is possible to operate in the following modes (any combination):
- PWM mode - 40kHz frequency, substituting adjustable 0-100%
- RC Mode - RC servo control, frequency 50 Hz + -90 degrees, precision steering servo 0.1 degree
- STEP mode - (in pairs out) - connect additional external converters for three stepper motors
   with the required interventions such as STEP-DIR.
- One output can also be used in conjunction with 0-10V analog output, and analog output can
  provide the speed and digital output indicates the direction of rotation - DIR.
For external drives, the frequency of generation of microsteps to 750kHz.

The module 3809 can be used for the CNC, but for a PLC application.
This is the binary inputs and outputs. The module includes:
- 16 digital inputs 0-24V. Inputs are optically isolated, combined for foursome, each entry in a foursome
       It can be switched with both polarities 0V and 24V. (Passed / not pass current through the input).
- 16 digital outputs 0-24V. The outputs are galvanically isolated, combined for foursome, each output in a foursome
       can switch to either 0V or 24V. Load approx. 2.5A.
A larger number of inputs or outputs can be achieved by adding the appropriate number of modules 3809.

We also plan to further modules which will include ADC, DAC and IRC inputs.
In the event that you have a system PiDiCNC - PiDiPLC interest, it is possible to design the modules according to your requirements.

Also demonstrated the system with one module 3805 can be viewed at the following video:
