====== 1.2 Principle of operation and functions ======

===== Principle of Operation =====

**IOL Connect Manager **software is a middle ware that connects IOL HAT to Node-RED and offers a web interface with to configure and test IO-Link devices. If also features an interface to a A SQLite database. Alternatively the **IOL Connect Manager **provides the IO-Link data via the Ethernet interface using JSON.

===== Functions =====

The core functions of the IOL Connect Manager are the same as for the interface of the Pinebox. Please refer to the Pinebox manual: [[pinebox:start|Pinebox Manual]]

The following sections also cover the functions of the IOL Connect Manager:

  * [[pinebox:01_manual:4_configuration:4-1_configuration-update|4.1 Device configuration and update]]
    * Note: The network, Wifi and LTE stick settings are not available in the IOL connect manager
  * [[pinebox:01_manual:4_configuration:4-2_port-configuration|4.2 Port configuration and control]]
  * [[pinebox:01_manual:5_node-red:5-1_process-data|5.1 Node-RED – Exchange Process Data]]
  * [[pinebox:01_manual:5_node-red:5-2_parameter-read|5.2 Node-RED – Reading Parameters]]
  * [[pinebox:01_manual:5_node-red:5-3_parameter-write|5.3 Node-RED – Writing Parameters]]
  * [[pinebox:01_manual:7_sqlite:7-1_create-delete-export|7.1 SQLite Database – Create, delete and export tables]]
    * Note: The database for export needs to be in the path relative to the IOL Connect Manager at sqlite/database.db
  * [[pinebox:01_manual:7_sqlite:7-3_sqlite-node-red|7.3 SQLite Database – Node-RED database node]]
    * Note: For database export, the database location and name is relative to the IOL Connect Manager at /home/zid/sqlite/database.db

The LED patterns on the IOL HAT per port are as in the section "Device Port Indicators": [[pinebox:01_manual:3_connections-web-interface:3-2-ui-and-ports]]

Please note:

  * Node-RED needs to be installed separately on the Raspberry Pi
  * For SQLite functions in Node-RED (read and write of data), the SQLite nodes need to be installed in Node-RED with the Palette Manager. The SQLite database is located in relative to the IOL Connect manager in sqlite/database.db
  * There is no SQLite viewer included with the IOL Connect Manager. An SQL viewer needs to be installed separately by the user if required.
