LIST OF MODBUS REGISTERS
The list below includes all available addresses on the PyroMiniBus sensor.
R = Read, W = Write
Address Length (words) Description R/W
0x00 1 Sensor Type (17 for PyroMiniBus) R
0x01 1 Field of view 0 for 2:1; 1 for 20:1 R
0x02 2 Serial number R
0x04 1 Modbus slave ID (slave address) R/W
0x05 1 Reflected Energy Compensation 0 for Off; 1 for On R/W
0x06 1 Reflected Temperature R/W
0x07 1 Emissivity Setting (1 LSB = 0.0001)
Minimum 0.2000, Maximum 1.0000 R/W
0x08 1 Hold Mode 0 for Off; 1 for Peak; 2 for Valley R/W
0x09 1 Hold Period (1 LSB = 0.1 seconds)
Minimum 0.1 seconds, Maximum 1200.0 seconds R/W
0x0A 1 Average Period (1 LSB = 0.1 seconds)
Minimum 0.1 seconds, Maximum 60.0 seconds R/W
0x0B 1 Average Temperature R
0x0C 1 Minimum Temperature R
0x0D 1 Maximum Temperature R
0x0E 1 Filtered Temperature R
0x0F 1 Unfiltered Temperature R
0x10 1 Sensor Temperature R
0x11 1 Status (bits active high)
Bit 0: Measurement error
Bit 1: Sensor temperature low
Bit 2: Sensor temperature high
Bit 3: Object temperature low
Bit 4: Object temperature high R
0x16 1 Reflected Temperature (not saved to non-volatile
memory)
R/W
0x17 1 Emissivity Setting (not saved to non-volatile
memory)
R/W
Notes:
1 All temperature are in tenths of degrees C
2 With the exception of addresses 0x16 and 0x17, all write operations are saved to non-
volatile memory
3 For further information please refer to http://www.modbus.org/specs.php
4 Use address 255 to communicate with any connected sensor (only one sensor
connected)
5 Use address 0 to broadcast to all connected sensors (no response expected)
