5.10.5.2.  Modbus-TCP 

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" 

 

Data  in  the  tree 

are  changed  after  modification  of  sensor  settings  and  validation  with 

. The star indicates that modifications have been made; these must be transferred to the 

HYDROCAL1005 unit for activation. This means, the settings indicated are not identical to those of 
HYDROCAL1005.  With  next  connection,  it  is  requested  whether  the  settings  on  HYDROCAL1005 
unit shall be updated (see chapter 

Error! Reference source not found.

). 

 

 

5.11 

Data transmission from / to the HYDROCAL1005 unit 

For transmission of data, the respective transformer menu must be selected in the root. In the lower 
part of the window, there are three selection buttons available for communication.
