Unofficial TwinCAT function for S7 Communication
This software is an (unofficial) opensource implementation of [TF6610 | TC3 S5/S7 Communication](https://www.beckhoff.com.ph/default.asp?twincat/tf6760.htm) similar to my other project [BeckhoffHttpClient](https://github.com/fbarresi/BeckhoffHttpClient).
## Main features
Your surely gonna love this software, but if you still need a couple of information for starring this project...
- **FREE! (for commercial use as well)**
- Resilient: doesn't matter what you do with the beckhoff (Start, Stop, Config-Mode, Run-Mode, etc.)
- Modern: build with the newest TwinCAT Version and .Net Core 3.1
- Clever: don't need to specify any datatype or bit numbering
## Requirements
- TwinCAT 3.1.4024.7+
## How to use this software
### Install and setup connections
- [Download](https://github.com/fbarresi/BeckhoffS7Client/releases/latest) the setup and install it on your beckhoff.
- Ajdust the settings file `TFU002.settings.json` located `C:\TwinCAT\Functions\Unofficial\BeckhoffS7Client` putting your connection parameters for all your S7 PLC in the settings file.
```json
{
"BeckhoffSettings": {
"AmsNetId": "",
"Port": 851
},
"ExtenalPlcSettings": [
{
"Name": "s7-300",
"IpAddress": "10.30.10.50",
"Port": 102,
"Rack": 0,
"Slot": 2
}
]
}
```
### Use The S7 Attribute
Use the S7 attribute in your project for connect your primitive variables (like an input or output) to a S7.
```reStructuredText
VAR_GLOBAL
{attribute 'S7.Out'}
{attribute 'S7.Address' := 'db2.dbx0.0'}
imAlive : BOOL;
{attribute 'S7.In'}
{attribute 'S7.Address' := 'db2.dbx1.0'}
{attribute 'S7.Plc' := 's7-300'} // you have to select a plc by name only if you have more then one
otherSystemAlive :BOOL;
END_VAR
```
### Supported TwinCAT Datatypes
- BOOL
- BYTE und BYTE[]
- INT / UINT
- DINT / UDINT
- LINT / ULINT
- REAL
### S7 Addressing rules
every address has the form (case unsenible) `DB..`
i.e.: `DB42.DBX0.7` => (means) Datablock 42, Bit (DBX), Start: 0, Position: 7 .
Following types are supported:
- `DBX` => Bit (BOOL)
- `DBB` => BYTE or BYTE[]
- `INT`
- `DINT`
- `DUL` => LINT
- `D` => REAL
### Logfiles
Logfiles are saved into `C:\TwinCAT\Functions\Unofficial\BeckhoffS7Client\Service.log`.
You can use [TailBlazer](https://github.com/RolandPheasant/TailBlazer) for a live view.
