Promotic

Communication with meters and regulators by the Rawet company (Czechia)

The manufacturer of measurement converters (http://www.rawet.cz, Czechia) for measuring temperature, both AC and DC electrical values, displays and PID regulators. All converters produce the output signal as current coil, the converters signed PPL or PXL include the RS485 communication line able to communicate via proprietary ASCII protocol or by the Modbus RTU protocol.

For the purpose of the communication with the PROMOTIC system for example the following converters can be used:
PPL110/112 – single/dual temperature converter
PXL310/312 – single/dual programmable converter of DC signals


Communication by the Modbus protocol:
For this communication in the PROMOTIC system can be used:
- PmModbusMr - Driver for communication by the Modbus Master protocol.
For easy integration of this driver into the application it is handy to use:
- Preconfiguration "PmModbusMr - Communication set with data and panel for non-defined device"


Rawet ASCII communication:
The ASCII communication protocol description see: http://www.rawet.cz/cz/download/protokol_ascii.pdf.
For this communication in the PROMOTIC system can be used:
- PmChar - Driver for communication by user defined ASCII/BIN protocol.
