Program transfer via PROFIBUS

TwinCAT offers a facility for transferring the user program to the Bus Terminal Controller over 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 2.55
• TwinCAT 2.9 Build 1025
Initializing the Bus Terminal Controller
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 the PROFIBUS, the ADS
interface must be enabled for the Bus Terminal Controller in the ADS tab. Save your settings and activate
the configuration. Then start the TwinCAT system and the cyclic task.

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 as controller, the PC or the Bus Terminal
Controller.
Two options 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 – the serial cable for communication via the RS232 interface [} 73]of the PC and the
programming interface of the Bus Terminal Controller
