Functioning

The flow diagram describes how the individual work steps are executed in a write command from the Crestron controller to the TwinCAT PLC.

Functioning 1:

Work steps:

  1. The write command is initiated by a positive edge on Beckhoff Switch By Name.
  2. It is forwarded to the Beckhoff Communication module for further supplements to the command parameters.
  3. The expanded write command is passed to the TCP/IP client for sending.
  4. The data is sent via TCP/IP.
  5. The TwinCAT Crestron Server receives the write command, converts it to an ADS request telegram and sends the data to the TwinCAT PLC.
  6. The PLC replies with an ADS response, which is received by the TwinCAT Crestron Server in order to log any errors that may have occurred.

Functioning 2:

Work steps:

  1. The write command is initiated by a positive edge on FB_CrestronWriteInt.
  2. It is sent to the TwinCAT Crestron Server as an ADS request. This converts the data received into a TCP/IP telegram that is understandable to Crestron and sends it to the Crestron controller via TCP/IP.
  3. An ADS Response, which carries information on the progress of the transmission, is generated in reply to the ADS Request. This ensures an appropriate reaction to any errors that have occurred.
  4. The data is sent via TCP/IP.
  5. The Crestron TCP/IP Client receives the data and forwards it to the Beckhoff Communication module for processing.
  6. The Beckhoff Communication module reacts to the data from the TCP/IP client and filters the information in order to then write the addressed signal with the transferred value.
