# PLCLogo Binding
|
|
|
|
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.
|
|
|
|
# Binding Configuration
|
|
|
|
This binding can be configured in the file `services/plclogo.cfg`.
|
|
|
|
| Property | Default | Required | Description |
|
|
|----------|---------|:--------:|-------------|
|
|
| `<plcname>`.host | | Yes | IP address of the LOGO! PLC |
|
|
| `<plcname>`.remoteTSAP | | Yes | `TSAP` (in hex) of the **remote** LOGO! PLC, as configured by LogoSoft Comfort. Common used value is 0x0200. |
|
|
| `<plcname>`.localTSAP | | Yes | `TSAP` (in hex) to be used by the **local** instance. Common used value is 0x0300. |
|
|
| `refresh` | 5000 | No | polling interval, in milliseconds, to be used when querying the Logo! |
|
|
|
|
## Item 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 is:
|
|
|
|
```
|
|
plclogo=”<instancename>:<memorylocation>”
|
|
```
|
|
|
|
## Examples
|
|
|
|
```
|
|
Switch ReadOutputQ13 {plclogo="plc:Q13"}
|
|
```
|
|
|
|
read value of output block `Q13` from Logo! device named 'plc'
|
|
|
|
```
|
|
Switch ReadWriteBinaryValue {plclogo="plc:VB0.0"} }
|
|
```
|
|
|
|
read/write binary input block mapped to `VB` address 0, bit 0
|
|
|
|
```
|
|
Number ReadWriteAnalogValue {plclogo="plc:VW5"}
|
|
```
|
|
|
|
read/write analog input block mapped to `VW` address 5
