Bastl PLC, was: Převodník ethernet - rs485

[Jan Waclawek]

Ja viem ze to nesplna povodnu poziadavku ani v cene ani v pouzitelnosti, a
tiez ano, je to reklama, ale bolo tu nadskrtnute bastlenie v smere PLC a
dnes mi prisla tato reklama od ST, tak sa mi to v hlave spojilo:

You can now build a real PLC, compliant with the most stringent
requirements, that can be programmed using common ladder-logic from your
smartphone through Wi-Fi.

Just plug together:

    an industrial input/output expansion board (X-NUCLEO-PLC01A1) with 8
digital outputs and 8 digital inputs,

    an industrial digital output expansion board (X-NUCLEO-OUT01A1) for an
additional 8 digital outputs,

    a Wi-Fi expansion board (X-NUCLEO-IDW01M1) to add wireless connectivity,

    an STM32 Nucleo-64 development board with a Dynamic Efficiency™
STM32F401 MCU (NUCLEO-F401RE) with support for Arduino and ST morpho
connectivity,

    download the STM32 ODE function pack for building a PLC controlled via
Wi-Fi (FP-IND-PLCWIFI1) and install the ST-PLC app (available for Android
and iOS) on your smartphone,

… and you’re ready to go.
