Communication with frequency converters by the Lenze company

Basic information:
- The frequency converters by the Lenze company support the Lecom-A/B communication protocol.
- The OPC server serves for the communication with this protocol.

Then the PROMOTIC application will communicate as a client by the OPC interface.
The usage OPC (the PmOpcUaClient communication driver or PmaOpcDaClient object) requires purchase of the "PmOPC" licence. When developing the application in the freeware mode PmFree, or with development environment and while testing it in runtime, this component is always functional.

The Lecom protocol is relatively simple text protocol and therefore the PmChar - Driver for communication by user defined ASCII/BIN protocol can be used for communication with the PROMOTIC system as well.
