Communication via ADS

The following describes how to establish communication via ADS with a Beckhoff device of the BK, BC, BX, and CX series. This requires the AmsServerNetId and IP address of the target system.

ADS router required The TwinCAT ADS router is also required for ADS communication. It is included in: TC1000, TwinCAT 3 ADS TX1100, TwinCAT I/O

Step 1: Select or manually enter a device.

Selection of a registered device

Click on the Name (1) combo box and select a registered device from the name list.

• If you select a registered device from the name list, the AmsServerNetId (2) and AdsPort (3) are automatically adopted.
• Here you can change the settings for the AdsPort. This is essential when communicating with a Beckhoff device, as they have different AdsPorts:
• The BK, BC, and BX series bus couplers and bus terminal controllers communicate via ADS port 100 (default value).
• The CX1xxx and CX9xxx series embedded PCs communicate via ADS port 28928.

Entering a device manually

If you want to enter a device manually, select User Defined in the name list.

• If you select User Defined from the Name (1) combo box in the name list, you must enter AmsServerNetId (2) and AdsPort (3) manually.

Step 2: Click on the Test (4) button to check the connection settings.

Possible causes for the following error message are:

• The terminals do not have sufficient power
• There is no connection
• The AmsServerNetId is invalid or an incorrect connection has been selected

The test was successful if the following dialog box appears.

Step 3: Click on the OK button to accept the set values.

Step 4: See chapter Login.
