Communication with frequency converters by the Lenze company
- 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.
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.
