Cautions during Use
Follow instructions in 'Cautions during Use'. Otherwise, it may cause unexpected
accidents.
The power supply should be insulated and limited voltage/current or Class 2, SELV
power supply device.
Do not install where strong magnetic or electric field exist. Otherwise, the resolution
may be adversely affected.
Mutual optical interference between laser sensors and photoelectric sensors may result
in malfunction.
Mutual optical interference between laser sensors may result in malfunction.
When connecting DC relay or other inductive load to the output, remove surge by using
diode or varistor.
Wire as short as possible and keep away from high voltage lines or power lines, to
prevent surge and inductive noise. [ Amplifier unit]
For the optimized performance, it is recommended to measure after 30 minute from
supplying power. [Amplifier unit]
Since external disturbance light (sunlight, fluorescent lighting, etc.) can cause product
malfunction, use the product with a light shield or slit. [Sensor head]
When detecting with the maximum sensitivity, an error may occur depending on each
characteristic deviation.

Modbus
The Modbus industrial protocol was developed in 1979 to make communication possible
between automation devices. T he protocol has expanded to include implementations over
serial, TCP/IP, and the user datagram protocol (UDP). Today, it is a common protocol used
by countless devices for simple, reliable, and efficient communica tion across a variety of
modern networks.
Refer to the reference document of developer for the details
Communication of BD-C series is based on Modbus RTU.

Autonics Modbus Address System
Parameter address structure
The parameter address is written in form Reference number - Decimal address
(Hexadecimal address).
For example, if the parameter address is 301001(03E8), it means that 3 is Reference
number, 01001 is Decimal address (DEC), 03E8 is Hexadecimal address (HEX).
Reference number per each FUNC

FUNC 04[R]

FUNC 03[R], FUNC 06[W], FUNC 16[MW]
Correlation between decimal address and hexadecimal address
The parameter address can be somewhat different for each manufacturer because the
regulation for a starting number is not defined.
Autonics Modbus address is started at 1 for decimal (DEC) address, and at 0 for
hexadecimal (HEX). So, decimal (DEC) address values are +1 for Hex (HEX)
address values.
03E8(HEX) →1001(DEC) (1000 + 1)
07D0(HEX) →2001(DEC) (2000 + 1)
157C(HEX) →5501(DEC) (5500 + 1)

2Modbus Mapping Table
The meaning of HI/LO address
Some parameters of BD series divide the value into two addresses (HI/LO) because it
exceeds the maximum value (216, 16 bit) that can be sent from one address.
When inputting value greater than the maximum (216, 16 bit), convert it to hexadecimal
(HEX), enter up to 4 digits (low 16bit) into the LO address and over 5 digits (high 16 bit)
into the HI address.
For example, when inputting a value 99999 into Output hysteresis parameter, convert
'99999' into the hexadecimal value, 1869F. Input 1(0x0001) into HI address (OUT HYS
HI [Output hysteresis], 400065(0040)) and 869F(0x869F) into LO address (OUT HYS LO
[Output hysteresis], 400066(0041)), and send them.
If under the maximum (216, 16 bit) is needed to be set, input ‘0’(0x0000) into HI address
and the hexadecimal value (HEX) into LO address.
