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.

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 theconverter 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 thevoltage 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 [0℃ 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.

⋆１．If the weighing device does not have an auto power-on function 1．If the weighing device does not have an auto power-on function or auto-start function, it is necessary to turn on the display or each weighing device by key operation after turning on the power.
⋆２．The AD4212D has two types of RS-232C connectors. Connect the display connector and the RS-232C connector of AD-8552EIP. (Do not use the PLC connector.)⋆３．Some functions (Adjustment error flag) cannot be used.
⋆４．Some functions (duiring rezero flag, sensitivity adjustment flag) cannot be used.
⋆５．The following models cannot use the during rezero flag. (EJ120B/EJ200B/EJ300B/EJ410B/EJ610B/EJ1500B/EJ2000B/EJ3000B/EJ4100B/EJ6100B)⋆６．Although the weighing device does not have an auto power-on function or an auto start function, it automatically shifts to the weighing display after the power is turned on, so no key operation is required.

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 terminalof the AD-8552EIP.

Caution●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 periodicallycommunicated 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.

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.

The data transferred from PLC etc. to the AD-8552EIP is called Output data.
Output data is used when outputting a command to the measuring instrument.

・The WEB interface is a function that allows to confirm the operation of the weighing device from a PC browser. The
WEB interface can be used to check the operation when starting up the production line or when troubleshooting.
Caution・Establishing communication between the WEB interface and EtherNet/IP at the same time is not recommended.
（It may conflict with EtherNet/IP communication.）・Communication may become unstable depending on the environment, so using for continuous connection andmonitoring are recommended.
・The browsers that have been confirmed to work are Microsoft Edge, Google Chrome, Mozilla Firefox, and Safari.

Confirmation and countermeasures

Make sure that power is properly supplied to the power supply terminal of the AD8552EIP.
・Is the voltage correct?（DC 24V）
・Is the cable connected correctly?
The connection with the scanner (PLC) has not been established.
・Is the IP address set so that it does not overlap?
・Is the signal output from the scanner?
The connection with the scanner (PLC) has timed out.
・Is the EtherNet/IP communication cable broken?
・Is the scanner turned on?
Turn the power of the AD-8552EIP off and then on again. When the power is turned
on, the changes made to the switch and WEB interface are read and reflected in theoperation.
Check the setting of the weighing device.
・Check the RS-232C communication settings of the corresponding channel.
・Is the output format of the weighing device set to the A&D standard format?

Turn the AD-8552EIP off and then on again. When the power is turned on, theswitch status is read and reflected in the operation.
