Fieldbus Components

Transmission via PROFIBUS

TwinCAT offers a facility for transferring the application program to the BC/BX via the fieldbus. The BC/BX can be
selected as the target system in PLC Control, after saving in the registry and restarting the TwinCAT system. The
TwinCAT-level TwinCAT PLC is necessary.

Minimum requirements:

FC310x with firmware from 2.0

TwinCAT 2.9 build 945

Initializing the BC/BX

The coupler must first be made known to the system before it can be selected in PLC Control.
Enter the Bus Terminal Controller in the System Manager, specify type, quantity and size of the fieldbus variables
and link them with a task. For the subsequent program download via PROFIBUS, the ADS interface has to be
activated in the ADS tab of the BC/BX. Save your settings and activate the configuration. Then start the TwinCAT
system and the cyclic task.

TwinCAT System Manager

PLC Control
When TwinCAT PLC Control is restarted, TwinCAT asks for the target platform, i.e. the device on which the user
program is later to run. TwinCAT offers two target platforms for the controller, the PC or the Bus Terminal Controller.

Two routes are available to you for transmission to the Bus Terminal Controller:

AMS for BCxx00 (Bus Terminal Controller without online change, one task)

AMS for BCxx50 and BX (Bus Terminal Controller with online change, two tasks)

BC serial - serial cable for communication via the RS232 interface of the PC and the programming interface
of the Bus Terminal Controller
