Compatibility - W.E.ST. PID-131-U Technical Documentation Manual

2.1 Compatibility

As a result of further developments some smaller changes have to be taken in consideration.
Functionality:
1. Downward compatible to the older modules.
2. 100 % wiring compatible.
3. Baud rate: The default baud rate has changed from 9600 baud to 57600 baud. This is adaptable in
WPC-300: OPTIONS/SETTINGS/INTERFACE.
FIXBAUDRATE = 57600 and/or AUTO BAUDRATE DETECTION = 57600
4. Technical enhancements:
- Programmable analogue output: only one version (U instead A and I) is necessary
Parameterization:
1. Standardizing of parameter names
2. Simplified and intuitive parameterization of the analogue inputs and sensors
3. Compatibility mode of the input scaling (AINMODE), if necessary
4. Adaptation of the output signal (current or voltages) and the polarity with the command SIGNAL:U (the
POL commando is removed)
