Modbus-TCP is always active on TCP Port 502.
Point-to-Point or Bus communication is not possible with Ethernet connection. Ethernet can be used
only with Modbus communication.
5.10.5.3. MODBUS
If one or more HYDROCAL1005 devices shall be integrated into a SCADA System for online moni-
toring, the MODBUS communication setup might be applicable. MODBUS is currently not supported
by HydroSoft, but the setup is shown here for completeness
Activate MODBUS using the RS 485 and the desired mode (RTU/ASCII)
Set a unique MODBUS address for
each device (1 … 247). Note: Communication with HYDRO-
CAL1005 can be made right now with up to 32 units
Setup "Answer Delay" if required (i.e. if communication problems occur)
Set "Baudrate", "Data Bits", "Parity" and "Stop bits"
