Documentation of the PLCLogo binding Bundle

Introduction

This binding provides native support of Siemens Logo! PLC devices. Communication with Logo is done via Moka7 library. Currently only two devices are supported: 0BA7 (Logo! 7) and 0BA8 (Logo! 8). Additionally multiple devices are supported. Different families of Logo! devices should work also, but was not tested now due to lack of hardware.
Binding works nicely at least 100ms polling rate.

This binding will be available from 1.9.0 onwards or is available from corresponding snapshot

Generic Item Binding Configuration

Follow blocks can be read from on both device types: I, Q, M, AI, AQ and AM. For Logo! 8 devices NI, NQ, NAI and NAQ are supported additionally. Contact items are used for digital inputs, Switch items for digital inputs/outputs and Number items for analog inputs/outputs.

Writing to the PLC can be done via VB (byte values) and VW (word values) for both device types. Use Switch items for writing of digital and Number of analog values.

The configuration pattern for Contact and Switch items is
plclogo=”<instancename>:<memorylocation>.<maskbit>”

Configuration pattern of Number items will be
plclogo=”<instancename>:<memorylocation>”

Some examples are listed below.

Binding Configuration in openhab.cfg
