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 Ether Net/IP.
- The measurement value can be reset to zero (re-zero) by operation from the host (PLC or PC).
- hen 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 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

Communication in Ether Net/IP
- When an Ether Net/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 Ether Net/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.
| Applicable model | Sensitivity adjustment method | Outline of procedure |
| AD-4212C | External weight ⋆１ | While monitoring the balance status with the Input data(Instance100), it is necessary to instruct data acquisition by Output data(Instance150) and to load and unload the weight on the weighing instrument. |
| AD-4212D | External weight ⋆１ | |
| Built-in weight | After instruction by Output data(Instance150), the Input data (Instance100) monitors until calibration is completed. |
⋆１．When changing the weight value to be used, refer to the instruction manual of the individual weighing device.

The initial value is “0xFFFFFFFF”. When you return to the weighing mode, it will return to the initial value.
Example of Adjustment weighing value for weighing device (CH1)
| Weight value | Byte | Name | Contents | Data | Remarks |
| 100g | 14 to 17 | CH1 Adjustment weight value | Adjustment weight value | 0x00000064 | ⇒ 100 |
9-6 Operating example（When connected to the AD-4212C/AD-4212D）
This is the procedure for performing basic operations on the weighing device via EtherNet/IP communication.
（Describes the case where a weighing device is connected to CH1. When using CH2, 3, 4, make the data layout correspond to the relevant CH (channel).）
■ How to read the weighing value (Weighing device CH1))
| Steps | Items | Contents | Input data layout (Instance150, Attribute3) | Output data layout (Instance100 ,Attribute3) | Status confirmation contents | |
| AD-4212C | AD-4212D | |||||
| 1 | Confirmation of decimal point position | Refer to the corresponding data layout. | Byte 6,7 [CH1 Decimal point position] | Confirm the decimal point position eg) 0x0003 → Decimal point 3 digits | ||
| 2 | Confirmation of weighing unit | Refer to the corresponding data layout. | Byte 8,9 [CH1 Weighing unit] | Confirm the corresponding unit of weighing value eg) 0x0000 → Unit：g | ||
| 3 | Confirmation of weighing value※１ | Refer to the corresponding data layout. | Byte 0-3 [CH1 Weighing value] | Confirm the weighing value eg) 0x00BC614E → 12345678 | ||
| Byte 4,5 [CH1 Status information] | Confirm the status information eg) 0x0000 → Stable weighing value | |||||
| 4 | Determines the measured value by steps 1 to 3 | eg) 12345.678 g (stable) | ||||
| 5 | Repeat steps 3 to 4.※2 | |||||
※１．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.
※２．If you change the decimal point position or unit, or if you want to use the smart range function, perform steps 1 and 2 as necessary.
■ Execution example of rezero (zero reset) (Weighing device CH1)
| Steps | Items | Contents | Input data layout (Instance150, Attribute3) | Output data layout (Instance100 ,Attribute3) | Status confirmation contents | |
| AD-4212C | AD-4212D | |||||
| 1 | Instructs to start rezero | Sets “1” to the corresponding data layout | Byte 0,1 [CH1 Command] Bit 3 (“R” command) | |||
| 2 | Confirms to start of rezero | Refer to the corresponding data layout. | Byte 4,5 [CH1 Status information] bit3 | Waits until bit3 changes from 0 to 1※３ | ||
| 3 | Confirms during rezero | Refer to the corresponding data layout. | Byte 4,5 [CH1 Status information] bit3 | Waits until bit3 changes from 1 to 0 | ||
| 4 | Confirms the completion of rezero | Refer to the corresponding data layout. | Byte 0 to 3 [CH1 Weighing value] | Confirms to become 0x00000000※４ | ||
| 5 | Command clear | Sets “0” to the corresponding data layout | Byte 0,1 [CH1 Command] Bit 3 (“R” command) | |||
※ 3．Normally, changes immediately after setting “1” to the corresponding data layout in the previous step.
When the weighing value is stable, rezeroing is completed instantly and bit3 returns to “0”, so the “1” state may not be read depending on the reading timing.
※ 4．If weighing value is unstable, re-zero cannot be executed. Be sure to confirm completion of re-zero by confirming that the weighing value is “0x00000000”.
■Example of calibration (sensitivity adjustment) with external weight（Possible only with AD-4212C／AD-4212D）
