1.Introduction
Thank you for purchasing the AD-8552EIP EtherNet/IP converter.
Please read this manual completely before using the AD-8552EIP.
1-1 Features
The AD-8552EIP converts the RS-232C communications of the weighing device into EtherNet/IP.
■The measurement value can be reset to zero (re-zero) by operation from the host (PLC or PC).
■When connected to an AD-4212C and AD-4212D, etc., it is possible to change the response speed, perform calibration
with an external weight, and supply power from the weighing device.
■The hooks on the back of the AD-8552EIP allow one-touch mounting on a DIN rail.

This unit Protective cover
1-2 Cautions
Before use, confirm the following articles for safe operation.
Grounding The Converter
Be sure to ground this converter.
Separate this earth ground line from others, like ground line of a motor, inverter or a power source. Unless the
converter is grounded, it may result in receiving an electric shock, cause operation error or catch fire.
Proper Power Source And Power Cable
Confirm the AC voltage, frequency and power tolerance of the power cable (refer to “4. Power Terminal”). If the
voltage range of the cable is lower than the power line voltage, it may cause leakage or catching fire. Use pole
compression terminals to connect the power cable to the terminals.
Splashing Water
The module is not water-resistant type.
Flammable Gas
Do not install the converter where flammable gas is present.
Heat Radiation Of The Module
Space out instruments to radiate heat sufficiently.
Do not use in an environment where the ambient temperature exceeds the operating temperature range [-10℃to
+50℃, 85% RH or less (no condensation)].
This unit is covered with a transparent plastic protective cover at the time of shipment.
After installing and connecting, be sure to remove the protective cover before turning on the power.
If it is used without removing the protective cover, this unit will overheat.
The protective cover is for preventing the entry of wire scraps and the like during installation and connecting.
Do not remove it until installation and connecting are complete.
②
Remove the two tabs on the lower
surface of the protective cover and
remove the protective cover.

4. Power Terminal
4-1 Power-supply voltage
Connect a constant voltage of external power supply (+ 10% -15%) within the range of 24 VDC to the DC power input terminal
of the AD-8552EIP.
●Do not use at a voltage exceeding the rated voltage range (24 VDC +10%-15%)
・Doing so may cause failure or heat generation.
・This unit may not operate normally.
●Ground the FG terminal of the switching power supply used for the power supply of this unit.
●The power line of this unit should be dedicated for this unit, and be separate from other drive devices.
・If strong noise is generated from the power line of another device, this unit may be damaged.
・This unit may not start normally due to the inrush current of other drive devices.
・Depending on the circuit configuration of this unit, other drive devices may not operate normally.
●Select a switching power supply capacity of approximately 9W per unit for the dedicated power supply line for this unit.
・If the power capacity is insufficient, this unit may not operate normally.

9. Communication in EtherNet/IP
・When an EtherNet/IP connection is established between the AD-8552EIP and the PLC, data is periodically
communicated by cyclic data. Cyclic data consists of "9-2 Output data" and "9-3 Input data".
・Weighing values can be read and zero reset (rezero) is possible.
・If you are using the following models, you can calibrate (Sensitivity adjustment) via EtherNet/IP.
When calibrating with a weighing device other than the following models, operate with the keys of the weighing device
while looking at the display of the measuring instrument.

*AD-8552EIP factory setting（normally, the factory setting of AD-4212C / AD-4212D is the same.）
2. Set the following setting items so that the host (PLC, PC, etc.) and AD-8552EIP are the same.
<Setting example>

[192.168.0.1]
[192.168.0.2]
*Make sure that IP addresses do not overlap in the connected network.
3. Refer to ”4-2 Connecting example”, “5-2 Connections”, “6-2 Connecting cable” for connecting.
・Normally, when using the AD-4212C/AD-4212D, power can be supplied from the RS-232C terminal, so connecting
to the power terminal of the AD-4212C/AD-4212D is not required.
・When connecting to the AD-4212D, connect to the AD-8552EIP using the AD-4212D display connector.
4. Turn on the device power.

■Details of the Output data
・Command output [CH1～4 Command] (CH1:byte 0,1、CH2:byte 2,3、CH3: byte 4,5、CH4: byte 6,7)
The following command is output to the weighing device connected to CH1-4.
※1．The AD-8552EIP outputs each command to the connected instrument when a "1" is written.
※2．The operation differs depending on the weighing device. For individual operation commands, refer to "3-2
Applicable model" or the instruction manual of the relevant weighing device.

※1．The flag does not change when operated with the keys of the weighing device.
※2．This flag can be used only when connected to the AD-4212C / D.
Caution: Be sure to read "Weighing value" and "Weighing value status information" at the same time. If they
are read separately, the correspondence between the "weighing value" and the "weighing value
status information" may differ depending on the update timing, so the weighing value status cannot
be determined accurately.
