Phone/tablet as BYOD (Bring Your Own Device) HMI/SCADA in a local network

HMI android wi-fi wifi plc phone tablet touch smartphone pad modbus/tcp rtu LAN BYOD Bring Your Own Device

Communication over Wi-Fi between a mobile device with HMI Droid and the PLC either directly (eg Modbus/TCP or Siemens S7 Communication) or through a serial port via a port server (eg COMLI or Modbus RTU).

Connection type should be set to TCP/IP, or UDP/IP when using SattBus COMLI.

HMI Droid can be used e.g. with WiFi PLCs from XLogic Sweden. (Select protocol Modbus/TCP class 1.)

Port server tested with HMI Droid and works well is MOXA NPort 5110.

Phone/tablet as BYOD (Bring Your Own Device) HMI/SCADA over mobile internet

HMI android wi-fi wifi plc phone tablet smartphone pad touch modbus/tcp rtu mobile internet BYOD Bring Your Own Device

Communication over mobile internet between a device with HMI Droid and the PLC either directly (eg Modbus/TCP or Siemens S7 Communication) or through a serial port via a port server (eg COMLI or Modbus RTU).

Connection type should be set to TCP/IP, or UDP/IP when using SattBus COMLI.

Router configured for "port forwarding".

If the IP address on the Internet is not fixed, you can use a dyn-dns service.

HMI Droid can be used e.g. with WiFi PLCs from XLogic Sweden. (Select protocol Modbus/TCP class 1.)

Port server tested with HMI Droid and works well is MOXA NPort 5110.

Using a VPN tunnel is recommended. Many routers and NAS devices have built-in VPN servers that are easy to setup.

Phone/tablet as BYOD (Bring Your Own Device) HMI/SCADA over Internet behind Carrier-grade NAT

Communication over Internet between a device with HMI Droid/Odrid HMI and a PLC behind Carrier-grade NAT either directly (eg Modbus/TCP or Siemens S7 Communication) or through a serial port via a port server (eg COMLI or Modbus RTU).

Connection type should be set to TCP/IP, or UDP/IP when using SattBus COMLI.

NOTE: Since there is no public IP-address to connect to, a service like e.g. ZeroTier is required.

HMI Droid can be used e.g. with WiFi PLCs from XLogic Sweden. (Select protocol Modbus/TCP class 1.)

Port server tested with HMI Droid and works well is MOXA NPort 5110.

Odrid HMI on a Mac in a local network

Requirements: macOS 10.15 or later.

Communication over Ethernet between a Mac and the PLC either directly (eg Modbus/TCP or Siemens S7 Communication) or through a serial port via a port server (eg COMLI or Modbus RTU).

Connection type should normally be set to Wi-Fi.

Odrid HMI can be used e.g. with WiFi PLCs from XLogic Sweden. (Select protocol Modbus/TCP class 1.)

Port server tested with Odrid HMI and works well is MOXA NPort 5110.

Panel-PC, ODROID or Raspberry Pi in a local network

Communication over ethernet between panel PC, ODROID or Raspberry Pi with HMI Droid and the PLC either directly (eg Modbus/TCP or Siemens S7 Communication) or through a serial port via a port server (eg COMLI or Modbus RTU).

Connection type should be set to TCP/IP, or UDP/IP when using SattBus COMLI.

HMI Droid can be used e.g. with WiFi PLCs from XLogic Sweden. (Select protocol Modbus/TCP class 1.)

Port server tested with HMI Droid and works well is MOXA NPort 5110.

Media player or PC with Android-x86 in a local network
