5. Next steps

The libraries' own documentation

Each library has its own guide, with a getting-started page, a reference for
every block and pin, worked examples and troubleshooting.

Library	Start with
ModBee Node UIO	node-uio docs: analog inputs and outputs, calibration, retained variables, pulse counting, sleep
ModBee Node UIO Web UI	node-webUI docs
BeeBus	modbee-beebus docs
Modbus	modbee-modbus docs
MQTT and Sparkplug B	modbee-mqtt docs
GSM	modbee-gsm docs
OTA	modbee-ota docs
ModBee Utilities	modbee-utilities docs
ModBee Devices	modbee-devices docs

Every block also explains itself in the editor: select it in the Library
panel and its description appears in the box below the library tree.

The Node UIO hardware

Wiring, terminals, power, the analog inputs' voltage or current setting
(a solder bridge on the board), and HATs are in the
modbee-node-uio repository.

The OpenPLC Editor

The ModBee editor works like the OpenPLC Editor, so OpenPLC's own
documentation applies: the languages, the editor's screens and debugging.
See the OpenPLC Editor documentation.
Remember that ModBee boards and libraries need the
ModBee editor.

Things to try next

Read an analog sensor: add an ANALOG_IN block after DIGITAL_IN, and
see node-uio analog.
Keep a value through a power cut: declare it RETAIN. See
retained variables.
Run a pump properly: the modbee-utilities pump blocks add run
feedback, faults, alarms, run hours and HMI messages.
Talk to other devices: a Modbus sensor on RS485 with modbee-modbus,
or report to SCADA with modbee-mqtt.
