Beckhoff PLC Connectivity
ProtoTwin Connect supports the ADS (Automation Device Specification) protocol for connection to Beckhoff Automation PLCs.
Server Configuration
Click the “Add Server” button in the “Servers” tab of the IO Browser and configure the server as follows:
- Protocol: Select “ADS” from the list.
- Name: Enter a (preferably) unique name, which will be used to identify the server.
- Host: Enter the AMS Net ID for the PLC.
- Port: Enter the port number (typically 851).
- Scan Rate: Enter the desired scan rate, which is the interval (in seconds) at which ProtoTwin Connect will read and write tag values.
Note that the scan rate is the desired interval at which tags are read and written. The actual rate will depend on the performance of the PLC and networking latency. You can set the scan rate to zero in order to read/write as fast as possible.
Save the configuration to add the server.
Importing Tags
Select the server and then click the “Import Tags” button to automatically import all the compatible tags from the PLC. Please note that ProtoTwin Connect does not currently support UDTs or Arrays. Please refer to the IO Browser documentation for the complete list of supported data types.
