Standard Method 2
Task:
–
The input channels are to be operated in different configurations.
The channels are to be configured first (4x00
After configuration, the measured values are to be read (0x00
–
Configuration of the channels:
Parameter
Filtering by mean-
value generation:
Format:
Measuring range: 0 V to 50 V
Procedure:
1
Install the terminal.
2
Connect the voltage (power up).
3
Configure each individual channel in the terminal in turn (initialization phase; e.g., in the
initialization phase of the application program).
4
Read the measured value for each channel in turn.
Initialization phase:
The appearance of the process data output word OUT[0] is as follows for all channels:
