Drehstromzähler DTS353F-2

Installation

1. 1Wire the RS-485 A and B terminals of the YTL DTS353F-2 to the corresponding terminals on your ModbusCloud MCG or MLP series gateway.
2. 2Set the Modbus slave address on the DTS353F-2 using its front panel buttons, and note the address for gateway configuration.
3. 3Confirm that the meter is configured to 9600 baud and odd parity, which matches the default settings of this template.
4. 4Power on the gateway, connect it to your local network, and verify it appears online in the ModbusCloud platform.
5. 5Import the DTS353F-2 template from the ModbusCloud template library and assign it to the correct gateway and slave address.
6. 6Check the live data view in ModbusCloud to confirm that voltage, current, power, and energy values are updating correctly.

Things to watch for

01

I see zero or incorrect values for total active energy but other registers read fine. What is wrong?

Total active energy is located at register address 256, which is outside the main register block (14 to 34). Verify that your gateway polling range includes address 256. The template should handle this automatically, but a manual check can help.

02

What baud rate and parity settings does the DTS353F-2 require?

The default communication settings are 9600 baud with odd parity (1 stop bit). These must match on both the meter and the ModbusCloud gateway. A mismatch will result in communication timeouts.

03

How do I interpret the float32 registers correctly?

Each measurement occupies two consecutive 16-bit Modbus registers, forming a 32-bit IEEE 754 floating point value. The template preconfigures the correct byte order. If you see very large or very small nonsensical values, check that the word order (big-endian vs. little-endian) in the gateway matches the meter.

04

What is the register at address 258 used for?

Address 258 contains an analog sensor value, but the manufacturer does not specify a unit for it. The template includes this register for completeness. You can ignore it if it is not relevant to your project.
