| Terminal | Label | Default Setting (Manual Page 23) | | :--- | :--- | :--- | | 6 | AI1 | Universal Input (Default: 0-10V for pressure sensor) | | 7 | AI2 | Universal Input (Default: 4-20mA for temperature) | | 8 | GND | Analog Ground | Weierwei Vev-3288s Manual
For automation engineers, the inability to find the Weierwei Vev-3288s Manual often means losing the Modbus map. Here is the essential table for integrating this device into a PLC or SCADA system.
Default Communication Settings: 9600 Baud, 8 Data bits, 1 Stop bit, No Parity (8N1).
| Parameter | Modbus Address (Decimal) | Holding Register (Hex) | Data Type | Access | | :--- | :--- | :--- | :--- | :--- | | Process Value (PV) | 40001 | 0x0000 | 16-bit Integer (x10) | Read | | Setpoint (SV) | 40002 | 0x0001 | 16-bit Integer (x10) | Read/Write | | Output % (Heating) | 40003 | 0x0002 | 0-1000 (0.0% to 100.0%) | Read | | Alarm Status | 40010 | 0x0009 | Bitmap | Read | | Run/Stop Command | 40020 | 0x0013 | 0=Stop, 1=Run | Write | Understanding the menu map is crucial for advanced
Note: To write a setpoint of 75.5 degrees, send the integer 755 to address 40002.
If you are using a 4-20mA loop, you must set the internal DIP switch SW1 to the "Current" position. Failure to do so will result in a "Sensor Err" code on the display.
