Schneider Electric RS485 Instruction Manual

23 March 2021

Easy UPS 3S 208 V UL RS485 Modbus Register
Map

The three pins for RS485 are shown below.

Notes:

1. Function codes 3 are supported

2. Modbus serial RTU and ASCII is supported.

3. Single-register reads of reserved or undefined registers will return an error. Block reads which begin
with a valid register will return zeros for undefined registers.

4. Strings are two characters per register, first character in high-order byte, second character in low-order
byte. Printable ASCII only.

5. Format column: "int "=signed 16-bit integer, " Unsigned int " = unsigned 16-bit integer.

6. Input three phase and output one phase series just have phase A, the registers of phase B and C be
reserved.

- Default speed : 9600 Baud

- Data format : ASCII

- Parity : None Parity

- Number of stop bit : 1 Stop Bit
