As most PLCs and data sources use proprietary communication protocols, these protocols are implemented in a so-called communication driver.
| • | Thecommunication driver has an ID consisting of a few characters. |
| • | A connection to a data source or PLC is designated as a communication channel. |
| • | Connections to several and different data sources can be defined at the same time. |
| • | The communication channels are defined in the Hosts tables. |
The following drivers are currently available:
