1.1 Product Description
I. The interface module is used externally to convert FATEK HMI RS485’s communication port (Modbus RTU) to a RJ45 connector
II. The main controller is in charge of the management and dynamic configuration of I/O parameters and so on.
III. The power module and interface module are standard for remote I/Os and users can choose the model or brand they prefer.
FATEK HMI Connection Setup
This chapter explains how to use the FvDesigner program to connect FATEK HMI with .For detailed information, please refer to FATEK FvDesigner User Manual
2.1 FATEK HMI Hardware Connection
I. The connection port is at the bottom of the machine. Take P5070N for example. It uses COM3 (RS485 pin)
 |
|||
| PIN# | COM3 (RS-422) | COM3 (RS-485) | COM4 |
| 1 | DATA+ | ||
| 2 | DATA- | ||
| 3 | ISO_GND | ISO_GND | ISO_GND |
| 4 | RX+ | ||
| 5 | RX- | ||
| 6 | TX+ | DATA+ | |
| 7 | TX- | DATA- | |
II. Connect the COM (RS485 6/7) at the bottom of the machine to the interface module (1/2) to convert it into a RJ45 connector, which will be connected to the main controller.
2.2 FATEK HMI Connection Setup
I. Launch FvDesigner, open a new file, select the controller page and then click on “Add” 
II. Or you can click to open an existing file, select “Project Management” page and then click on “Connect” 
III. Connection method setup
Ⓐ From the “Communication Interface Type” drop-down menu, select ”Connect Directly (Serial Port)”
Ⓑ From the “Manufacturer” drop-down menu, select ”MODBUS IDA”
Ⓒ From the “Product Series” drop-down menu, select ”MODBUS RTU”
Ⓓ From the “Connection Port” drop-down menu, select ”COM3”
Ⓔ From the “Transmission Rate” drop-down menu, select “115200”
Ⓕ From the “Calibrate” drop-down menu, select “No”
Ⓖ From the “Data Bits” drop-down menu, select “8”
Ⓗ From the “Stop Bits” drop-down menu, select “1”
Ⓘ Set up based on the device
Notes:
※The demonstration in the Connection Operating Manual uses COM3.
For using 485 pin with COM3, please refer to 2.1FATEK HMI Hardware Connection.
※Regarding ’s parameter settings, please refer to Control Module Operating Manual.
IV. Set up the location for the tag register 
Ⓐ From the “Device” drop-down menu, select the device to be connected
Ⓑ From the “Type” drop-down menu, select “4x”
Ⓒ Set up according to the plan
Example:
| register address |
HMI’s corresponding address* | |
| R | 0x1000 | 4097 |
| R | 0x1001 | 4098 |
| R | 0x1000.0 | 4097 |
| W | 0x2000 | 8193 |
| W | 0x2001 | 8194 |
| W | 0x2000.0 | 8193 |
Note:
※HMI’s corresponding address: ’s first GFDI-RM01N has the register address at 1000(HEX) converted to 4096(DEC)+1
’s first GFDO-RM01N has the register address at 2000(HEX) converted to 8192(DEC)+1
※Regarding ’s register address and format, please refer to Control Module Operating Manual
