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 of the PmaOpcDaClient object requires purchase of the "PmOPC" licence. With the freeware version PmFree, or when developing the application (with development environment for testing purposes), 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.
