Sentiotec SentiotecThis function block connects a sentiotec sauna controller via the serial interface. Sauna, evaporator, light, fan, auxiliary output, preset time, user programs and heating time limit can be switched or set; the states and measured values of the sauna controller (heater, bench and foil temperature, humidity) are polled continuously and provided at the outputs.
The connection runs at 57600 baud, 8 data bits, 1 stop bit, no parity. The states are polled in turn about every 100 ms; commands are sent with priority.
Important: The inputs are only evaluated if they are linked to the variables created for this block with Create variables (Ctrl+G) (main group 2316). A command is sent whenever one of these variables is written - even if the value does not change. Other addresses at the inputs do not trigger a command.
If the block is disabled or the backup controller is in standby, the interface is not occupied and no commands are sent.

Parameters |
||
| Commport | Serial interface: Onboard (RS485 of the controller), USB (adapter on the USB port) or Manual. | |
| Commport manual | Only with commport "Manual": name of the interface, e.g. /dev/ttyUSB1. | |
| Protocol | Line ending of the commands: V1 (command+semicolon+LF) or V2 (command+CRLF). Which variant is required depends on the software of the sauna controller. | |
| Debug | Writes all sent and received lines to the diagnostics messages. Only enable for troubleshooting. | |
