Address Range Limit
The address range for device types 0x, 1x, and 0x_multi_coils can be configured. This option should be used when the controller’s bit register address range is not a multiple of 16. For example, if the range is 0x1 ~ 0x6 or 0x9 ~ 0x14, communication will not be possible. To ensure effective communication between the HMI and the controller, please follow the configuration instructions below.
0x-1~6
0x_1-9~14
Conversion
The 3x_Double and 4x_Double address types are added. If [ABCD ->CDAB] check box is selected, please select 3x_Double and 4x_Double address types.

1: MAX1W and 4X_32Bit read/write 1 word for each packet and display a 32-bit value, whereas MAX2W reads/writes 2 words for each packet.
Note2: Go the [System Parameter Settings] -> [Device Properties] and click [Conversion] to set the data format of device types 3x, 4x, 6x, 3x_double, 4x double.
Note3: Read/write a Bit at a time. Value 0 and 1 are used to represent ON or OFF status where 0 means set OFF and 1 means set ON.
Note4: The number of bits to read can be set in Macro; therefore, it is recommended to use 0x address type for functions such as GetData() and SetData(), in order to increase reading speed.
To read/write multiple 0x address tytypesn ma acro, use 0x_multi_coils to increase write speed.
Note5: Please assign all the addresses to Even addresses, or all to Odd addresses, in order to prevent communication failure.
Note 6: EBPro V6.03.02 or later supports 64-bit data type (cMT Series only), but please note that the address limit range is 48 bits in maximum..
NOTE:
Address type “5x” is mapped to Holding Register. The communication protocol of 5x is almost the same as “4x” except that “5x” swaps double word.
If 4x contains the following information:
| Address | 1 | 2 | 3 | 4 | 5 | 6 | … |
| Data in word | 0x1 | 0x2 | 0x3 | 0x4 | 0x5 | 0x6 | |
| Data | 0x0201 | 0x0403 | 0x0605 | ||||
For 5x, it will be:
| Address | 1 | 2 | 3 | 4 | 5 | 6 | … |
| Data in word | 0x1 | 0x2 | 0x3 | 0x4 | 0x5 | 0x6 | |
| Data | 0x0102 | 0x0304 | 0x0506 | ||||
Modbus RTU function code:
| Device type | Read | Write |
| 0x | 0x01 Read coil | 0x05 Write single coil |
| 0x_multi_coils | 0x01 Read coil | 0x0f write multiple coils |
| 1x | 0x02 Read discrete input | X |
| 3x / 3x_Bit | 0x04 Read input register | X |
| 4x / 4x_Bit | 0x03 Read holding register | 0x10 Write multiple registers |

Frequently Asked Questions
- Q: What is the purpose of the conversion in a PLC setting?
A: The conversion setting is used to manage the data format of specific device types such as 3x, 4x, and others. It allows for proper data interpretation and communication between the HMI and the controller. - Q: How does address type 5x differ from address type 4x?
A: Address type 5x is mapped to Holding Register and swaps double words compared to address type 4x. The communication protocol for both is similar, with the main distinction being the double word swapping in address type 5x. - Q: What are the options available for device properties conversion?
A: To set the data format of device types like 3x, 4x, and others, navigate to [System Parameter Settings] -> [Device Properties] and click on [Conversion]. This allows you to configure the data format based on your requirements.
