Function blocks and faceplates for evaluation of the diagnostic interface "COM" and visualization of the device data
The diagnostic interface "COM" of the PSU6200 provides a signal that transmits the following device data as a Manchester code:
- Voltage and current values
- Nominal data
- Device information
- Temperature and operating hours
The following library provides function blocks for SIMATIC S7-1200/S7-1500 and faceplates for SIMATIC Comfort Panels. The function blocks enable you to read in and evaluate the signal of the diagnostic interface "COM" via a digital input at the S7-CPU. You can use the faceplates to clearly display the device data on an HMI control panel.
The library blocks for SIMATIC S7-1500 can also be used in an ET 200SP CPU and ET 200pro CPU.
The following image shows the graphic representation of the solution.
