Delta DOP Series HMI Connection ManualDOP-A/AE/AS Series
Modbus nW (Master) | Back to Table |
A. HMI factory settings
Baud rate: 9600, 7, EVEN, 1. (ASCII)
9600, 8, EVEN, 1. (RTU)
Controller station number: 1.
Control area/status area: W40100 / W40200.
NOTE
1)This driver can read consecutive communication address on the screen via one Modbus command to improve the communication efficiency. For example, if there are 6 devices on the screen, and read the data of the addresses W40100, W40101, W40102, W40200, W40201, W40300. It will read three times. It will read W40100 3 Words at the first time, read W40200 2 Words at the second time and read W40300 1 Word at the third time.
2)Ensure to check the box next to “Optimize” (Optimization for reading) selection in “Communication” tab in the “Configuration” dialog box in “Options” menu (Options Æ Configuration Æ Communication). If “Optimize” selection is unchecked, do not select “Data Length Limit”.
