Operating Guide
3.
Modify the PROFIBUS DP address. There are 2 ways to modify the address.
-
Modifying by software.
In configuration software SST-MP-CFG, select Custom for PROFIBUS address in the fieldbus.
Write the DP address and download the configuration to the PROFIBUS DP module.
-
Modifying by button.
To enter the PROFIBUS DP address setting state, double-click the button (LED high bit is blinking, and low bit is on).
To increase the digit by 1, click the button once.
Press the button for 2.5 s to switch to the setting state for the low bit of the address.
To increase the digit by 1, click the button once.
Press the button for 2.5 s to save and apply the new address.
4.
Configure the hardware in the PROFIBUS master modeling software.
-
a.
Install the GSD file.
-
b.
Drag the input/output module to the required slot. Compile and download.
-
c.

5.
Connect the PROFIBUS DP module with serial port devices through the RS485/RS422/RS232 terminals.
-
a.
Turn off the power.
-
b.
Correctly connect the terminals.
6.
Connect the PROFIBUS DP module with the PROFIBUS DP master station. Use thePROFIBUS DP terminal. See

4.5 Software Configuration
4.5.1 Fieldbus Configuration
To access fieldbus configuration, select Fieldbus in the device view. The configurable items include:
•
Input valid data length
-
Valid only when subnet protocol type is "User Config".
-
Open: The first byte of PROFIBUS input data is used to indicate the length of the serial port received data.
-
Close: There are no bytes of the PROFIBUS input data which indicate the length of the serial port received data.
•
PROFIBUS address
-
"Setting by Hardware": Modify the PROFIBUS DP slave address with the button on the PROFIBUS DP option.
-
"Customized": Input the DP address in the textbox of "PROFIBUS Address".
4.5.2 Subnet Configuration
The Subnet configuration depends on the selected protocol type.
Protocol type: Modbus Master
•
Modbus communication baud rate: 300, 600, 1200, 2400, 9600, 19200, 38400, 57600, or 115200 bps
•
Data bits: 8 bits
•
Parity check mode: None, odd, even, mark, or space
•
Stop bits: 1 or 2
•
Transmission mode: RTU or ASCII
•
Response timeout: When the Modbus master sends commands, the range of the time waiting for response from the slave is
300–60000 ms.
•
Delay between polls: After one Modbus command has been sent and has received correct response, or the response has timed
out, the range of the delay time before next command being sent is: 0–2500 ms.
•
Output mode: Modbus writing command (output command) has 3 output modes.
