How to use Siemens' WinCC V13 configuration software to enable direct communication between a delicate panel and the S120 drive? This example demonstrates communication between the TP1200 Comfort panel and the CU320-2DP.
The network setup is as follows:
**Profibus Network Addresses:**
- CU320-2DP: 1
- TP1200: 0
**Device Numbers for CU and Servo Axes:**
**WinCC V13 Configuration Steps:**
1. **Add HMI Station in TIA Portal:**
2. **After opening the project, create a new connection:**
3. **Create variables with proper addressing rules:**
**Variable Addressing Rules:**
- DB = Parameter Number
- DBX = 1024 × Device Number + Parameter Index (can be W or D, depending on data type).
**Examples of Reading and Writing Parameters:**
- Read/Write CU P2098.1: Variable address is DB2098.DBD1025, data type: DWORD.
- 1025 = 1024 × 1 (device number) + 1 (parameter index)
- Read/Write SERVO_02 P2900.0: Variable address is DB2900.DBD2048, data type: REAL.
- 2048 = 1024 × 2 (device number) + 0 (parameter index)
To set the speed reference P1155 of the drive, you can map it to P2900. Then, by changing the value of P2900, you can adjust the motor speed.
On the touch screen, create an I/O field and connect it to the variable:
This configuration ensures smooth and accurate communication between the HMI and the drive system, allowing real-time control and monitoring.
