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.

Address setting via EE-PCS Product Configuration Software
1
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
0
Setting the DIP switches to any other address than 0, overrules the
1
slave address set via configuration software (permitted values: 1...247).
Example: Slave address set to 11 (= 0000 1011 binary).
