5.2.2 Address Switch
Address Switch
Address Switch
Address setting via EE-PCS Product Configuration Software
All DIP switches at position 0 → address has to be set via
Product Configuration Software
Factory setting: 239 (permitted values: 1…247).
Example: Slave address is set via configuration software.
Address setting via DIP switch
Setting the DIP switches to any other address than 0, overrules the
slave address set via configuration software (permitted values: 1…247).
Example: Slave address set to 11 (= 0000 1011 binary).

Tab. 2 Data transmission
ID address, baud rate, parity and stop bits can be set via:
1. EE-PCS, Product Configuration Software and the appropriate configuration cable.
2. Modbus protocol in the register 60001 (0x00) and 60002 (0x01). See Application Note Modbus
AN0103 (available on www.epluse.com/EE211)
The measured values are saved as a 32 bit float value and as 16 Bit signed integer, see the Modbus
Register map below.
The serial number as ASCII-code is located at read register address 30001-30008 (16 bit per address).
The firmware version is located at register address 30009 (bit 15...8 = major release; bit 7...0 = minor
release).
The sensor name is located at register address 30010.
