3 Terminal configuration

Note

The terminal can be configured and parameterized by way of the internal
register structure. Each terminal channel is mapped in the bus coupler. The
terminal’s data is mapped differently in the bus coupler’s memory
depending on the type of the bus coupler and on the set mapping
configuration (e.g. Motorola/Intel format, word alignment etc.).

Contrary to the analog and output terminals, in the case of the KL1501 the
control and status byte is always also mapped, regardless of the field bus
system used.

Lightbus coupler BK2000

In the case of the Lightbus coupler BK2000, the control /status byte is
always mapped besides the data bytes. It is always in the low byte at the
offset address of the terminal channel.

Profibus coupler BK3000

When using the Profibus coupler BK3000, the KL1501 is automatically
mapped with 5 bytes of input data and 5 bytes of output data.
