BECKHOFF BK3000 - Manual (Page 14)

Basic information
14 BK3xxx/LC3100
Electrical data
The Profibus couplers differ by virtue of their capacity levels and maximum
baud rates. The BK30xx variants are capable of supporting up to 1.5
MBaud and the LC3100 and BK31xx series support up to 12 Mbaud. The
electrical data specific to the fieldbus is given in this chapter. The following
data distinguishes between a standard and an economy variant (BK3x00
and BK3x10) and an low cost variant (LC3100). Compatability with the
Profibus is guaranteed in any case. Contrary to the standard bus coupler,
the economy variant is limited of the number of I/O´s. Thus, there is no
possibility of connecting inputs and outputs other than digital ones. The
following table lists an overview of all data:
