== OpenPLC runtime ==

The default Debian Flexbuild system image for SL-AIoT-BOX with SpaceSOM-8Mplus has OpenPLC runtime installed and enabled (https://autonomylogic.com/docs/openplc-overview/). After running the system, the OpenPLC webserver can be accessed using the network name or IP address with 8080 port:
* http://somlabs-aiot-box-8mplus:8080
* <IP address>:8080

The IP address can be checked after logging to the serial console as root (no password) and calling ''ip a'' command.

The default webserver login credentials are:
* username: openplc
* password: openplc

== Setting hardware ==

OpenPLC requires correct hardware driver to support hardware inputs and outputs. The driver for the SL-AIoT-BOX is called ''SoMLabs IoT Box'' and should be selected in ''Hardware'' window. After clicking ''Save changes'' the driver will be compiled.

SL-IoT-BOX has six binary outputs and four binary inputs configured for OpenPLC programs. They are mapped as follows:

== Demo application ==

OpenPLC runtime executes programs built using OpenPLC IDE (https://autonomylogic.com/). The example project and pre-compiled program can be downloaded here: [[Media:Openplc_6ull_demo.zip|Openplc_demo.zip]]

This example uses all four binary inputs to control binary outputs and two relays as shown on the project scheme.
