Firmware version of the Bus Couplers

Required firmware A particular firmware version may be required for operating the KL6201/KL6211 AS-i master terminals on the Bus Coupler / Bus Terminal Controller (see table below).

In delivery state the KL6201/KL6211 is set to a process image of 12 bytes. Most Bus Couplers and Bus Terminal Controllers listed in the table support the 6-byte and 12-byte process images.
Bus Couplers / Bus Terminal Controllers that are not listed

• require a terminal firmware version from B7 for operating the 6-byte or 12-byte process image on the KL6201/KL6211;
• are not yet prepared for operating the 22-byte or 38-byte process image.

The delivered firmware version is shown on the back of the Bus Coupler (see example below for CANopen).

If required, the firmware can be updated via the serial interface (KS2000 cable required) or - depending on the bus system - via the fieldbus. The current firmware versions and the program for the firmware update can be found on our home page at http://www.beckhoff.de.

Support of the different process images by the firmware versions of the Bus Couplers / Bus Terminals Controllers

*) only if the Bus Coupler is set to complete mapping of the Bus Terminals (e.g. via the KS2000 configuration software). On delivery, these Bus Couplers are set to compact mapping of the Bus Terminals.
