13.8.6.1 Communication interface
submenu
The communication interface is a serial
RS285 computer interface for the remote
control of the high-pressure nozzle system.
With this computer interface, all control oper-
ations which can be carried out on the screen
can also be carried out by the building tech-
nology control system, for example.
The MODBUS-RTU Protocol is used to trans-
mit the control commands (separate docu-
mentation on this is available from
HygroMatik).
