BACnet protocol settings
PLEASE NOTE
The recommended settings for multiple devices in a BACnet MS/TP network are 38 400, 8, none, 1.
The HTS201 PICS (Product Implementation Conformance Statement) is available on the E+E website at
www.epluse.com/hts201.
BACnet address and baud rate can be set via:
▪
PCS10 Product Configuration Software and the USB configuration adapter HA011066.
The PCS10 can be downloaded free of charge from www.epluse.com/pcs10.
▪
BACnet protocol, see the PICS.

Modbus RTU protocol settings
PLEASE NOTE
The recommended settings for multiple devices in a Modbus RTU network are 9600, 8, even, 1.
Device address, baud rate, parity and stop bits can be set via:
▪
EE-PCS Product Configuration Software and the USB configuration adapter HA011066.
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 www.epluse.com/hts201).
The serial number as ASCII-code is located in read-only registers 1 - 8 (0x00 - 0x07, 16 bits per register).
The firmware version is located in register 9 (0x08) (bit 15...8 = major release; bit 7...0 = minor release). The
sensor name is located in registers 10 - 17 (16 bits per register).
NOTICE
When reading the serial number or the sensor name, it is always necessary to read all 8 registers, even if the
desired information requires less.
NOTICE
For obtaining the correct floating point values, both registers have to be read within the same reading
cycle. The measured value can change between two Modbus requests, exponent and mantissa may get
inconsistent then.
