How to communicate energy meter (conserv make Em6400,rs 485 communication)with Elipse scada
@Kannan_Suresh, good afternoon.
According to the manufacturer’s manual, the factory settings are (see page 40):
"7.3. Factory Settings
- Communication Protocol: Modbus – RTU
Baud Rate: 9600 bps
Data bits: 8
Stop bits: 1
Parity: Even
- Data type: 32-bit Float (Real) for all parameters unless otherwise specified.
Except for parameter:
- INTR (Number of interruptions (Outages) in RMS parameter blocks) – unsigned 32-
bit integer data type. - RunSec (Run Seconds in Integrated block) – unsigned 32-bit integer data type.
-
Data Format: Direct reading from the meter, no scaling is required.
-
Modbus Function code: 03 (Read)"
In this case , you should use the Modbus Master driver. Download Link.
In “Modbus” tab , configure Modbus RTU .
In the “Setup” tab , set the physical layer as Serial .
In the “Serial” tab , choose the same parameters configured on the meter.
To configure the IO tags, use the meter address map available here and the driver documentation provided with the DLL.

I hope it helps.
Hi…as per my knowledge you need a Modbus RTU/Modbus TCP gateway such as Moxa MB3180 or a HMS Anybus gateway to convert between the two protocols. Then you just have to add a Modbus Channel to WinCC, configure it to the gateway IP address and slave number and add the tags you want to read.
