Address Setting
DIP switch
DIP switch
Address setting via PCS10 Product Configuration Software:
All DIP switches at position 0 address has to be set via configuration software
(factory setting: 45).
Example: Address is set via configuration software.
Modbus address setting via DIP switch:
Setting the DIP switch to any other address than 0 overwrites the address selected via
configuration software.
Example: Address set to 11 (=00001011 binary).

Modbus Protocol
The recommended settings for multiple devices in a Modbus RTU network are 9600, 8, Even, 1. The room sensor represents 1 unit
load in a Modbus network.
Device address, baud rate, parity and stop bits can be set via:
▪PCS10 Product Configuration Software and the the appropriate configuration cable HA011018.
The PCS10 can be downloaded free of charge from www.epluse.com/pcs10.
▪Modbus protocol in the register 1 (0x00) and 2 (0x01).
See Application Note Modbus AN0103 (available at the according product website).
The serial number in ASCII format is located in read-only register 1 - 8 (16 bits per register). The firmware version is located in
register 9 (bit 15...8 = major release; bit 7...0 = minor release). The sensor name is located in registers 10 - 17 (16 bits per register).
