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
, i.e. by the PmaOpcClient
object, the PROMOTIC will be connected to the OPC server and thus communicate with the devices.
Usage of the PROMOTIC OPC client component requires purchase of the PmOpcClient 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.
