Communication with Lenze frequency converters
- The frequency converters of 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" license. With the freeware version PmFree, or when developing the application (with development environment for tersting purposes), this component is always functional.
protocol is relatively simple text protocol and thus the PmChar - Driver for communication by user defined ASCII/BIN protocol
can be used for communication with the PROMOTIC system as well.
