Control functions
Softcontrol Data/F offers the possibility of a TCP / IP connection for communication with ex-
ternal control systems such as a PLC or similar. To control Softcontrol Data/F and to receive
measurement data, a defined data packet must be sent to the parameterized port (factory setting:
port = 2000). Softcontrol Data/F responds within the same TCP / IP transport channel.
Note:
The cycle time for sending data to Softcontrol Data/F must not be shorter than 1 second!
The data packet to be sent to Softcontrol Data/F must be structured according to the following
scheme:
Packet length - 8 bytes

Note:
After a "calibration" a sensor quality check has been triggered, it can take up to 15
minutes to complete a new sensor quality.
A data packet with all measured values and status information is sent back for every data packet
sent. This data package is structured as follows:
