Janitza UMG-96 Modbus TCP

Installation

1. 1Mount the Janitza UMG-96 in the switchboard and wire the voltage and current inputs according to the manufacturer's installation manual.
2. 2Connect the UMG-96 to the local IP network using its Ethernet port and assign a static IP address via the meter's configuration menu.
3. 3Verify that Modbus TCP is enabled on the UMG-96 and note the configured TCP port (default is 502).
4. 4Connect the ModbusCloud gateway (MCG or MLP series) to the same IP network and ensure it can reach the meter's IP address.
5. 5Import the Janitza UMG-96 Modbus TCP template in the ModbusCloud platform and enter the meter's IP address and Modbus unit ID.
6. 6Confirm live data appears on the ModbusCloud dashboard by comparing displayed values with the meter's local display.

Things to watch for

01

What byte order does the UMG-96 use for float32 registers?

The UMG-96 uses big-endian (AB CD) byte order for its float32 registers. This is the default in the ModbusCloud template, so no manual byte-swap configuration should be needed.

02

Why do I see zero or incorrect values even though the connection is established?

Check that the register start address is set to 19000 and that each register is configured as a two-word float32 read. An off-by-one addressing error or wrong data type will produce zero or nonsensical values.

03

Can I connect multiple UMG-96 meters to a single ModbusCloud gateway?

Yes. Each meter needs its own IP address on the network. Add a separate device instance in ModbusCloud for each meter using the same template but with the corresponding IP address.

04

Does the UMG-96 require a specific firmware version for Modbus TCP support?

Modbus TCP is supported on standard UMG-96 firmware. However, if you experience connection issues, verify that the firmware is up to date using the Janitza GridVis software.
