1. Introduction
The AD-4411 is a weighing indicator that converts signals from strain gauge load cells and connects them toan Industrial Ethernet network. It contributes to an efficient system by connecting weighing instruments toindustrial control systems in plants and factories.
- Two communication ports enable daisy-chain connection without a switching hub.
- 7-segment green LED display with a character height of 10 mm and display resolution of ±999999.
- High-speed AD conversion of 1200 times/second and a digital filter enable high speed and accurate weighing.
- DIN96x48 panel mount type with IP65 protection on the front panel.
- Settings can be updated with a PC via a USB port.

1.1. Safety precautions
If the equipment is used in a manner not specified by the manufacturer, the protection provided by theequipment may be impaired.
Please read the following precautions carefully before using this product.
WARNING・ Provide an external safety circuit for the indicator so that the safety of the whole system can be
secured even if errors occur in the external power supply or the indicator.
・ This indicator must be used indoors. Do not use the indicator in the following environments:- where the temperature and the humidity exceed the specifications- where there are corrosive or flammable gases- where the indicator could be subjected to oil, chemicals, or water
Please note that securing the indicator to the control panel provides IP65 protection to the outside of
the control panel.
・ Turn off all external power supplies when installing or removing the indicator.
・ Turn off all external power supplies when wiring the indicator.
・ Be sure to ground the indicator.

CAUTION・ Do not clamp control wires or communication cables with power lines, and do not position them close
to power lines.
・ Position the load cell cable a sufficient distance away from high frequency circuits such as high voltage
power lines or inverter load circuits.
・ When the front cover have dirt, wipe them with wet soft cloth. Do not use organic solvent such likebenzine, thinner and alcohol. Doing so may result in deformation or discoloration of the unit.
・ Suitable for use at pollution degree of 2 or less.
・ Use within an altitude of 0 to 2000m.
・ To an external connection port connect the circuit separated from a dangerous voltage by adouble/reinforced insulation.

9.4.2.2. Read command
Refer to "15 Function setting lists" for commands for read setting values.
The following are commands for reading measured values.

Command

Description

1001

Read displayed value

1003

Read gross value

1005

Read net value

1007

Read tare value

1095

Read load cell input voltage (1nV/V)

The decimal point position is ignored when the setting value / measured value is read.
For example, the displayed value "123.4" is read as "1234".

Use the following procedure to read a setting value.
1.

Set the command "0" in the "Command" area on PLC.

2.

When AD-4411 accepts the command "0", it echoes back "0" in the "Response" area and waits for acommand from PLC.

3.

Set a valid read command in the "Command" area on PLC.

4.

If AD-4411 successfully reads the data, it echoes back the command in the "Response" area and updates
the read data in the "Response value" area. If it fails, the "Response" area is updated to 65535: Error.

The following is an example of reading FncF10 and setting value "35".

9.4.2.3. Write command
Refer to "15 Function setting lists" for commands for writing setting values.
The decimal point position is ignored when writing setting values.
For example, the value to be written is "12" when the value set is "1.2".

Use the following procedure to write a setting value.
1.

Set the command "0" in the "Command" area on the PLC.

2.

When AD-4411 accepts the command "0", it echoes back "0" in the "Response" area and waits for acommand from PLC.

3.

Set valid write data in the "Command value" area on PLC.

4.

Set a valid write command in the "Command" area on PLC.

5.

If AD-4411 successfully writes the data, it echoes back the command in the "Response" area and the write
data in the "Response Value". If it fails, the "Response" area is updated to 65535: Error.

The following is an example of writing FncF10 and setting value "35".

10. USB
A PC can be used to read measured values and write setting values via USB (virtual COM port).
AD-4411 can be operated via USB bus power, but the USB circuit is not isolated, so noisy environments may
affect measurement performance. For normal operation, use the 24 V power supply port.

10.1. Communication specification
USB function is available in measurement mode.
