1.2 MODBUS settings
The default settings is of the MODBUS/RTU module is:
-
Mode = Slave
-
Protocol = RTU
-
Card Id = 1
-
Baud-rate = Selectable (See the CN2 paragraph)
-
Stop-bit = 1
-
Parity = none
-
Responce-delay = 5 milliseconds
 | Accepted modbus requests | |
|---|---|---|
| Type request | Description | |
| 3 | Read Holding Register | |
| 6 | Write Single Holding Register | |
| 16 | Write Multiple Holding Register | |
1.3 HA548.04 setup data setting
Enter to the HA548.04 setup and to set the following parameters:
| Code | Description | Value |
|---|---|---|
| rS | RS 485 Enable | 1 |
| br | RS 485 Speed transmission | 9600 |
| db | Number of the data bits | 8 |
| Sb | Number of the stop bits | 1 |
| PA | Paruty bit | 0 |
| rc | Delay of the character transmission | 5 |
| CI | Address code | 1 |
1.4 Diagnostic
The 4 leds L1, L2, L3, L4 shows the diagnostic:
-
L1 = Transmission to HA548.04 in progress
-
L2 = Receive from the HA548.04 in progress
-
L3 = Modbus message in working
-
L4 = Configuration error
| For reset the communication errors, press the RESET button |
|---|
2. Testing with PC program
To test the modbus functionality on the PC, you must use a program “Modbus RTU Master”.
You can use the ModScan32 program of WinTech (www.win-tech.com)
 | Connect properly the USER port (CN2 pins 4A, 5A, 5B) to the serial port of the PC, and then set the dips SW2.1-5 OFF e SW2.6 ON. |
|---|
2.1 Setup ModScan32 program
Press to menù Connection → Connect:
-
Select the serial port on your PC (eample COM2)
-
then in the Configuration section, to set Modbus communication data (Baudrate can be selected as described under CN2)
-
then in Protocol Selection, to set the data as in the following picture
 | Length must not exceed the value of 32, otherwise it must be done a reboot of the instrument. |
