BC7300 23
Assignment of the Bus Terminals
In the default setting, all the Bus Terminals are assigned to the Bus
Terminal Controller. This can be changed with the KS2000 software. The
assignment of the terminals is specified in Table 1 of the BC7300.
Hex Bin Description
0 00 The Bus Terminal is assigned to the MODBUS, and byte-
oriented Bus Terminals are given compact mapping (user
data only)
1 01 No function
2 10 The Bus Terminal is assigned to the BC, and byte-oriented
Bus Terminals are given compact mapping (user data only)
3 11 The Bus Terminal is assigned to the BC, and byte-oriented
Bus Terminals are given complex mapping (with control
and status)
Compact Compact evaluation of a byte-oriented Bus Terminal means that only the
user data is transmitted.
Example: a KL3xx2 has 2 input words, and a KL4xx2 has 2 output words.
Complex
Complex evaluation of a byte-oriented Bus Terminal means that the user
data and the control and status byte are transmitted.
Example: a KL3xx2 has 4 input words and 4 output words; the same
applies to a KL4xx2.
You will find further information in the documentation for the Bus
Terminals.

KS2000 example
As from Version 2.3.2, the KS2000 software permits the adaptation of the
Bus Terminals to be set via a dialogue. You can update your KS2000
software at www.Beckhoff.de.
